AI From the Sky: Stealth Entrepreneur’s Drone Platform Sees into Mines

Christian Sanz isn’t above trying disguises to sneak into places. He once put on a hard hat, vest and steel-toed boots to get onto the construction site of the San Francisco 49ers football stadium to explore applications for his drone startup.

That bold move scored his first deal.

For the entrepreneur who popularized drones in hackathons in 2012 as founder of the Drone Games matches, starting Skycatch in 2013 was a logical next step.

“We decided to look for more industrial uses, so I went and bought construction gear and was able to blend in, and in many cases people didn’t know I wasn’t working for them as I was collecting data,” Sanz said.

Skycatch has since grown up: In recent years the San Francisco-based company has been providing some of the world’s largest mining and construction companies its AI-enabled automated drone surveying and analytics platform. The startup, which has landed $47 million in funding, promises customers automated visibility over operations.

At the heart of the platform is the NVIDIA Jetson TX2-driven Edge1 edge computer and base station. It can create 2D maps and 3D point clouds in real-time, as well as pinpoint features  to within five-centimeter accuracy. Also, it runs AI models to do split-second inference in the field to detect objects.

Today, Skycatch announced its new Discover1 device. The Discover1 connects to industrial machines, enabling customers to plug in a multitude of sensors that can expand the data gathering of Skycatch.

The Discover1 sports a Jetson Nano inside to facilitate the collection of data from sensors and enable computer vision and machine learning on the edge. The device has LTE and WiFi connectivity to stream data to the cloud.

Changing-Tracking AI

Skycatch can capture 3D images of job sites for merging against blueprints to monitor changes.

Such monitoring for one large construction site showed that electrical conduit pipes were installed in the wrong spot. Concrete would be poured next, cementing them in place. Catching the mistake early helped avoid a much costlier revision later.

Skycatch says that customers using its services can expect to compress the timelines on their projects as well as reduce costs by catching errors before they become bigger problems.

Surveying with Speed

Japan’s Komatsu, one of the world’s leading makers of bulldozers, excavators and other industrial machines, is an early customer of Skycatch.

With Japan facing a labor shortage, the equipment maker was looking for ways to help automate its products. One bottleneck was surveying a location, which could take days, before unleashing the machines.

Skycatch automated the process with its drone platform. The result for Komatsu is that less-skilled workers can generate a 3D map of a job site within 30 minutes, enabling operators to get started sooner with the land-moving beasts.

Jetson for AI

As Skycatch was generating massive sums of data, the company’s founder realized they needed more computing capability to handle it. Also, given the environment in which they were operating, the computing had to be done on the edge while consuming minimal power.

They turned to the Jetson TX2, which provides server-level AI performance using the CUDA-enabled NVIDIA Pascal GPU in a small form factor and taps as little as 7.5 watts of power. It’s high memory bandwidth and wide range of hardware interfaces in a rugged form factor are ideal for the industrial environments Skycatch operates in.

Sanz says that “indexing the physical world” is demanding because of all the unstructured data of photos and videos, which require feature extraction to “make sense of it all.”

“When the Jetson TX2 came out, we were super excited. Since 2017, we’ve rewritten our photogrammetry engine to use the CUDA language framework so that we can achieve much faster speed and processing,” Sanz said.

Remote Bulldozers

The Discover1 can collect data right from the shovel of a bulldozer. Inertial measurement unit, or IMU, sensors can be attached to the Discover1 on construction machines to track movements from the bulldozer’s point of view.

One of the largest mining companies in the world uses the Discover1 in pilot tests to help remotely steer its massive mining machines in situations too dangerous for operators.

“Now you can actually enable 3D viewing of the machine to someone who is driving it remotely, which is much more affordable,” Sanz said.


Skycatch is a member of NVIDIA Inception, a virtual accelerator program that helps startups in AI and data science get to market faster.

Office Ready? Jetson-Driven ‘Double Robot’ Supports Remote Working

Apple’s iPad 2 launch in 2011 ignited a touch tablet craze, but when David Cann and Marc DeVidts got their hands on one they saw something different: They rigged it to a remote-controlled golf caddy and posted a video of it in action on YouTube.

Next came phone calls from those interested in buying such a telepresence robot.

Hacks like this were second nature for the friends who met in 2002 while working on the set of the BattleBots TV series, featuring team-built robots battling before live audiences.

That’s how Double Robotics began in 2012. The startup went on to attend YCombinator’s accelerator, and it has sold more than 12,000 units. That cash flow has allowed the small team with just $1.8 million in seed funding to carry on without raising capital, a rarity in hardware.

Much has changed since they began. Double Robotics, based in Burlingame, Calif., today launched its third-generation model, the Double 3, sporting an NVIDIA Jetson TX2 for AI workloads.

“We did a bunch of custom CUDA code to be able to process all of the depth data in real time, so it’s much faster than before, and it’s highly tailored to the Jetson TX2 now,” said Cann.

Remote Worker Presence

The Double helped engineers inspect Selene while it was under construction.

The Double device, as it’s known, was designed for remote workers to visit offices in the form of the robot so they could see their co-workers in meetings. Video-over-internet call connections allow people to see and hear their remote colleague on the device’s tablet screen.

The Double has been a popular ticket at tech companies on the East and West Coasts in the five years prior to the pandemic, and interest remains strong but in different use cases, according to the company. It has also proven useful in rural communities across the country, where people travel long distances to get anywhere, the company said.

NVIDIA purchased a telepresence robot from Double Robotics so that non-essential designers sheltering at home could maintain daily contact with work on Selene, the world’s seventh-fastest computer.

Some customers who use it say it breaks down communication barriers for remote workers, with the physical presence of the robot able to interact better than using video conferencing platforms.

Also, COVID-19 has spurred interest for contact-free work using the Double. Pharmaceutical companies have contacted Double Robotics asking how the robot might aid in international development efforts, according to Cann. The biggest use case amid the pandemic is for using the Double robots in place of international business travel, he said. Instead of flying in to visit a company office, the office destination could offer a Double to would-be travelers.


Double 3 Jetson Advances

Now shipping, the Double 3 features wide-angle and zoom cameras and can support night vision. It also uses two stereovision sensors for depth vision, five ultrasonic range finders, two wheel encoders and an inertial measurement unit sensor.

Double Robotics will sell the head of the new Double 3 — which includes the Jetson TX2 — to existing customers seeking to upgrade its brains for access to increasing levels of autonomy.

To enable the autonomous capabilities, Double Robotics relied on the NVIDIA Jetson TX2 to process all of the camera and sensor data in realtime, utilizing the CUDA-enabled GPUs and the accelerated multimedia and image processors.

The company is working on autonomous features for improved self-navigation and safety features for obstacle avoidance as well as other capabilities, such as improved auto docking for recharging and auto pilot all the way into offices.

Right now the Double can do automated assisted driving to help people avoid hitting walls. The company next aims for full office autonomy and ways to help it get through closed doors.

“One of the reasons we chose the NVIDIA Jetson TX2 is that it comes with the Jetpack SDK that makes it easy to get started and there’s a lot that’s already done for you — it’s certainly a huge help to us,” said Cann.

Startup’s AI Platform Allows Contact-Free Hospital Interactions

Hands-free phone calls and touchless soap dispensers have been the norm for years. Next up, contact-free hospitals.

San Francisco-based startup Ouva has created a hospital intelligence platform that monitors patient safety, acts as a patient assistant and provides a sensory experience in waiting areas — without the need for anyone to touch anything.

The platform uses the NVIDIA Clara Guardian application framework so its optical sensors can take in, analyze and provide healthcare professionals with useful information, like whether a patient with high fall-risk is out of bed. The platform is optimized on NVIDIA GPUs and its edge deployments use the NVIDIA Jetson TX1 module.

Ouva is a member of NVIDIA Inception, a program that provides AI startups go-to-market support, expertise and technology. Inception partners also have access to NVIDIA’s technical team.

Dogan Demir, founder and CEO of Ouva, said, “The Inception program informs us of hardware capabilities that we didn’t even know about, which really speeds up our work.”

Patient Care Automation 

The Ouva platform automates patient monitoring, which is critical during the pandemic.

“To prevent the spread of COVID-19, we need to minimize contact between staff and patients,” said Demir. “With our solution, you don’t need to be in the same room as a patient to make sure that they’re okay.”

More and more hospitals use video monitoring to ensure patient safety, he said, but without intelligent video analytics, this can entail a single nurse trying to keep an eye on up to 100 video feeds at once to catch an issue in a patient’s room.

By detecting changes in patient movement and alerting workers of them in real time, the Ouva platform allows nurses to pay attention to the right patient at the right time.

The Ouva platform alerts nurses to changes in patient movement.

“The platform minimizes the time that nurses may be in the dark about how a patient is doing,” said Demir. “This in turn reduces the need for patients to be transferred to the ICU due to situations that could’ve been prevented, like a fall or brain injury digression due to a seizure.”

According to Ouva’s research, the average hospitalization cost for a fall injury is $35,000, with an additional $43,000 estimated per person with a pressure injury like an ulcer from the hospital bed. This means that by preventing falls and monitoring a patient’s position changes, Ouva could help save $4 million per year for a 100-bed facility.

Ouva’s system also performs personal protective equipment checks and skin temperature screenings, as well as flags contaminated areas for cleaning, which can reduce a nurse’s hours and contact with patients.

Radboud University Medical Center in the Netherlands recently integrated Ouva’s platform for 10 of its neurology wards.

“Similar solutions typically require contact with the patient’s body, which creates an infection and maintenance risk,” said Dr. Harry van Goor from the facility. “The Ouva solution centrally monitors patient safety, room hygiene and bed turnover in real time while preserving patients’ privacy.”

Patient Assistant and Sensory Experience

The platform can also guide patients through a complex hospital facility by providing answers to voice-activated questions about building directions. Medical City Hospital in Dallas was the first to pick up this voice assistant solution for their Heart and Spine facilities at the start of COVID-19.

In waiting areas, patients can participate in Ouva’s touch-free sensory experience by gesturing at 60-foot video screens that wrap around walls, featuring images of gardens, beaches and other interactive locations.

The goal of the sensory experience, made possible by NVIDIA GPUs, is to reduce waiting room anxiety and improve patient health outcomes, according to Demir.

“The amount of pain that a patient feels during treatment can be based on their perception of the care environment,” said Demir. “We work with physical and occupational therapists to design interactive gestures that allow people to move their bodies in ways that both improve their health and their perception of the hospital environment.”

Pixel Perfect: V7 Labs Automates Image Annotation for Deep Learning Models

Cells under a microscope, grapes on a vine and species in a forest are just a few of the things that AI can identify using the image annotation platform created by startup V7 Labs.

Whether a user wants AI to detect and label images showing equipment in an operating room or livestock on a farm, the London-based company offers V7 Darwin, an AI-powered web platform with a trained model that already knows what almost any object looks like, according to Alberto Rizzoli, co-founder of V7 Labs.

It’s a boon for small businesses and other users that are new to AI or want to reduce the costs of training deep learning models with custom data. Users can load their data onto the platform, which then segments objects and annotates them. It also allows for training and deploying models.

V7 Darwin is trained on several million images and optimized on NVIDIA GPUs. The startup is also exploring the use of NVIDIA Clara Guardian, which includes NVIDIA DeepStream SDK intelligent video analytics framework on edge AI embedded systems. So far, it’s piloted laboratory perception, quality inspection, and livestock monitoring projects, using the NVIDIA Jetson AGX Xavier and Jetson TX2 modules for the edge deployment of trained models.

V7 Labs is a member of NVIDIA Inception, a program that provides AI startups with go-to-market support, expertise and technology assistance.

Pixel-Perfect Object Classification

“For AI to learn to see something, you need to give it examples,” said Rizzoli. “And to have it accurately identify an object based on an image, you need to make sure the training sample captures 100 percent of the object’s pixels.”

Annotating and labeling an object based on such a level of “pixel-perfect” granular detail takes just two-and-a-half seconds for V7 Darwin — up to 50x faster than a human, depending on the complexity of the image, said Rizzoli.

Saving time and costs around image annotation is especially important in the context of healthcare, he said. Healthcare professionals must look at hundreds of thousands of X-ray or CT scans and annotate abnormalities, Rizzoli said, but this can be automated.

For example, during the COVID-19 pandemic, V7 Labs worked with the U.K.’s National Health Service and Italy’s San Matteo Hospital to develop a model that detects the severity of pneumonia in a chest X-ray and predicts whether a patient will need to enter an intensive care unit.

The company also published an open dataset with over 6,500 X-ray images showing pneumonia, 500 cases of which were caused by COVID-19.

V7 Darwin can be used in a laboratory setting, helping to detect protocol errors and automatically log experiments.

Application Across Industries

Companies in a wide variety of industries beyond healthcare can benefit from V7’s technology.

“Our goal is to capture all of computer vision and make it remarkably easy to use” said Rizzoli. “We believe that if we can identify a cell under a microscope, we can also identify, say, a house from a satellite. And if we can identify a doctor performing an operation or a lab technician performing an experiment, we can also identify a sculptor or a person preparing a cake.”

Global uses of the platform include assessing the damage of natural disasters, observing the growth of human and animal embryos, detecting caries in dental X-rays, creating autonomous machines to evaluate safety protocols in manufacturing, and allowing farming robots to count their harvests.

More Than a Wheeling: Boston Band of Roboticists Aim to Rock Sidewalks With Personal Bots

With Lime and Bird scooters covering just about every major U.S. city, you’d think all bets were off for walking. Think again.

Piaggio Fast Forward is staking its future on the idea that people will skip e-scooters or ride-hailing once they take a stroll with its gita robot. A Boston-based subsidiary of the iconic Vespa scooter maker, the company says the recent focus on getting fresh air and walking during the COVID-19 pandemic bodes well for its new robotics concept.

The fashionable gita robot — looking like a curvaceous vintage scooter — can carry up to 40 pounds and automatically keeps stride so you don’t have to lug groceries, picnic goodies or other items on walks. Another mark in gita’s favor: you can exercise in the fashion of those in Milan and Paris, walking sidewalks to meals and stores. “Gita” means short trip in Italian.

The robot may turn some heads on the street. That’s because Piaggio Fast Forward parent Piaggio Group, which also makes Moto Guzzi motorcycles, expects sleek, flashy designs under its brand.

The first idea from Piaggio Fast Forward was to automate something like a scooter to autonomously deliver pizzas. “The investors and leadership came from Italy, and we pitched this idea, and they were just horrified,” quipped CEO and founder Greg Lynn.

If the company gets it right, walking could even become fashionable in the U.S. Early adopters have been picking up gita robots since the November debut. The stylish personal gita robot, enabled by the NVIDIA Jetson TX2 supercomputer on a module, comes in signal red, twilight blue or thunder gray.

Gita as Companion

The robot was designed to follow a person. That means the company didn’t have to create a completely autonomous robot that uses simultaneous localization and mapping, or SLAM, to get around fully on its own, said Lynn. And it doesn’t use GPS.

Instead, a gita user taps a button and the robot’s cameras and sensors immediately capture images that pair it with its leader to follow the person.

Using neural networks and the Jetson’s GPU to perform complex image processing tasks, the gita can avoid collisions with people by understanding how people move  in sidewalk traffic, according to the company. “We have a pretty deep library of what we call ‘pedestrian etiquette,’ which we use to make decisions about how we navigate,” said Lynn.

Pose-estimation networks with 3D point cloud processing allow it to see the gestures of people to anticipate movements, for example. The company recorded thousands of hours of walking data to study human behavior and tune gita’s networks. It used simulation training much the way the auto industry does, using virtual environments. Piaggio Fast Forward also created environments in its labs for training with actual gitas.

“So we know that if a person’s shoulders rotate at a certain degree relative to their pelvis, they are going to make a turn,” Lynn said. “We also know how close to get to people and how close to follow.”

‘Impossible’ Without Jetson 

The robot has a stereo depth camera to understand the speed and distance of moving people, and it has three other cameras for seeing pedestrians for help in path planning. The ability to do split-second inference to make sidewalk navigation decisions was important.

“We switched over and started to take advantage of CUDA for all the parallel processing we could do on the Jetson TX2,” said Lynn.

Piaggio Fast Forward used lidar on its early design prototype robots, which were tethered to a bulky desktop computer, in all costing tens of thousands of dollars. It needed to find a compact, energy-efficient and affordable embedded AI processor to sell its robot at a reasonable price.

“We have hundreds of machines out in the world, and nobody is joy-sticking them out of trouble. It would have been impossible to produce a robot for $3,250 if we didn’t rely on the Jetson platform,” he said.

Enterprise Gita Rollouts

Gita robots have been off to a good start in U.S. sales with early technology adopters, according to the company, which declined to disclose unit sales. They have also begun to roll out in enterprise customer pilot tests, said Lynn.   

Cincinnati-Northern Kentucky International Airport is running gita pilots for delivery of merchandise purchased in airports as well as food and beverage orders from mobile devices at the gates.

Piaggio Fast Forward is also working with some retailers who are experimenting with the gita robots for handling curbside deliveries, which have grown in popularity for avoiding the insides of stores.

The company is also in discussions with residential communities exploring usage of gita robots for the replacement of golf carts to encourage walking in new developments.

Piaggio Fast Forward plans to launch several variations in the gita line of robots by next year.

“Rather than do autonomous vehicles to move people around, we started to think about a way to unlock the walkability of people’s neighborhoods and of businesses,” said Lynn.

Meet the Maker: YouTuber Insists It’s Easier Than You Think to Make Something Super Using AI

Alex Schepelmann went from being a teacher’s assistant for an Intro to Programming class to educating 40,000 YouTube subscribers by championing the mantra: anyone can make something super using AI and machine learning.

His YouTube channel, Super Make Something, posts two types of videos. “Basics” videos provide in-depth explanations of technologies and their methods, using fun, understandable lingo. “Project” videos let viewers follow along with instructions for creating a product.

About the Maker

Schepelmann got a B.S. and M.S. in mechanical engineering from Case Western Reserve University and a Ph.D. in robotics from Carnegie Mellon University. His master’s thesis focused on employing computer vision to identify grass and obstacles in a camera stream, and he was part of a team that created an award-winning autonomous lawnmower.

Now, he’s a technical fellow for an engineering consulting firm and an aerospace contractor supporting various robotics projects in partnership with NASA. In his free time, he creates content for his channel, based out of his home in Cleveland.

His Inspiration

In his undergrad years, Schepelmann saw how classmates found the introductory programming class hard because the assignments didn’t relate to their everyday lives. So, when he got to teach the class as a grad student, he implemented fun projects, like coding a Tamagotchi digital pet.

His aim was to help students realize that choosing topics they’re interested in can make learning easy and enjoyable. Schepelmann later heard from one of his students, an art history major, that his class had inspired her to add a computer science minor to her degree.

“Since then, I’ve thought it was great to introduce these topics to people who might never have considered them or felt that they were too hard,” he said. “I want to show people that AI can be really fun and easy to learn. With YouTube, it’s now possible to reach an audience of any background or age range on a large scale.”

Schepelmann’s YouTube channel started as a hobby during his years at Carnegie Mellon. It’s grown to reach 2.1 million total views on videos explaining 3D printing, robotics and machine learning, including how to use the NVIDIA Jetson platform to train AI models.

His Favorite Jetson Projects

“It’s super, super easy to use the NVIDIA Jetson products,” said Schepelmann. “It’s a great machine learning platform and an inexpensive way for people to learn AI and experiment with computationally intensive applications.”

To show viewers exactly how, he’s created two Jetson-based tutorials:

Machine Learning 101: Intro to Neural Networks – Schepelmann dives into what neural networks are and walks through how to set up the NVIDIA Jetson Nano developer kit to train a neural network model from scratch.

Machine Learning 101: Naive Bayes Classifier – Schepelmann explains how the probabilistic classifier can be used for image processing and speech recognition applications, using the NVIDIA Jetson Xavier NX developer kit to demonstrate.

The creator has released the full code used in both tutorials on his GitHub site for anyone to explore.

How Abyss Solutions Helps Keep Offshore Rig Operators Afloat

As its evocative name suggests, Abyss Solutions is a company taking AI to places where humans can’t — or shouldn’t — go.

The brainchild of four University of Sydney scientists and engineers, six years ago the startup set out to improve the maintenance and observation of industrial equipment.

It began by developing advanced technology to inspect the most difficult to reach assets of urban water infrastructure systems, such as dams, reservoirs, canals, bridges and ship hulls. Later, it zeroed in on an industry that often operates literally in the dark: offshore oil and gas platforms.

Abyss Solutions Lantern Eye output

A few years ago, Abyss CEO Nasir Ahsan and CTO Suchet Bargoti were demonstrating to a Houston-based platform operator the insights they could generate from the image data collected by its underwater Lantern Eye 3D camera. The camera’s sub-millimeter accuracy provides a “way to inspect objects as if you’re taking them out of water,” said Bargoti.

An employee of the operator interrupted the meeting to describe an ongoing problem the company was having with their topside equipment that was decaying and couldn’t be repaired sufficiently. Once it was clear that Abyss could provide detailed insight into the problem and how to solve it, no more selling was needed.

“Every one of these companies is dreading the next Deepwater Horizon,” said Bargoti, referencing the 2010 incident in which BP spilled nearly 5 million barrels of oil into the Gulf of Mexico, killing 11 people and countless wildlife, and costing the company $65 billion in cleanup costs and fines. “What they wanted to know is, ‘Will your data analytics help us understand what to fix and when to fix it?’”

Today, Abyss’s combination of NVIDIA GPU-powered deep learning algorithms, unmanned vehicles and innovative underwater cameras is enabling platform operators to spot faults and anomalies such as corrosion on equipment above and below the water and address it before it fails, potentially saving millions of dollars and even a few human lives.

During the COVID-19 pandemic, the stakes have risen. Offshore rigs have emerged as hotbeds for the spread of the virus, forcing them to adopt strict quarantine procedures that limit the number of people onsite in order to reduce the disease’s spread and minimize interruptions.

Essentially, this has sped up the industry’s digital transformation push and fueled the urgency of Abyss’ work, said Bargoti. “They can’t afford to have these things happening,” he said.

Better Than Human Performance

Historically, inspection and maintenance of offshore platforms and equipment has been a costly, time-consuming and labor-intensive task for oil and gas companies. It often yields subjective findings that can result in missed needed repairs and unplanned shutdowns.

An independent audit found that Abyss’ semantic segmentation models are able to detect general corrosion with greater than 90 percent accuracy, while severe corrosion is identified with greater than 97 percent accuracy. Both are significant improvements over human efforts, and also have outcompeted other AI companies in the audit.

What’s more, Abyss says that its oil and gas platform clients report reductions in operating costs by as much as 25 percent thanks to its technology.

Training of Abyss’s models, which rely on many terabytes of data (each platform generates about 1TB a day), occurs on AWS instances running NVIDIA T4 Tensor Core GPUs. The company also uses the latest versions of CUDA and cuDNN in conjunction with TensorFlow to power deep learning applications such as image and video segmentation and classification, and object detection.

Bargoti said the company also is working with the NVIDIA Jetson TX2 module and TensorRT software to condense its models so they can run on their unmanned vehicles in real time.

Most of the data can be processed in the cloud because of the slowness of the corrosion process, but there are times when real-time AI is needed onsite, such as when a robotic vehicle needs to make decisions on where to go next.

Taking Full Advantage of Inception

As a member of NVIDIA Inception, a program to help startups working in AI and data science get to market faster, Abyss has benefited from a try-before-you-buy approach to NVIDIA tech. That’s allowed it to experiment with technologies before making big investments.

It’s also getting valuable advice on what’s coming down the pipe and how to time its work with the release of new GPUs. Bargoti said NVIDIA’s regularly advancing technology is helping Abyss squeeze more data into each compute cycle, pushing it closer to its long-term vision.

“We want to be the intel in these unmanned systems that makes smart decisions and pushes the frontier of exploration,” said Bargoti. “It’s all leading to this better development of perception systems, better development of decision-making systems and better development of robotics systems.”

Abyss is taking a deep look at a number of additional markets it believes its technology can help. The team is taking on growth capital and rapidly expanding globally.

“Continuous investment in R&D and innovation plays a critical role in ensuring Abyss can provide game-changing solutions to the industry,” he said.

AI Goes Uptown: A Tour of Smart Cities Around the Globe 

There are as many ways to define a smart city as there are cities on the road to being smart.

From London and Singapore to Seat Pleasant, Maryland, they vary widely. Most share some common characteristics.

Every city wants to be smart about being a great place to live. So, many embrace broad initiatives for connecting their citizens to the latest 5G and fiber optic networks, expanding digital literacy and services.

Most agree that a big part of being smart means using technology to make their cities more self-aware, automated and efficient.

That’s why a smart city is typically a kind of municipal Internet of Things — a network of cameras and sensors that can see, hear and even smell. These sensors, especially video cameras, generate massive amounts of data that can serve many civic purposes like helping traffic flow smoothly.

Cities around the globe are turning to AI to sift through that data in real time for actionable insights. And, increasingly, smart cities build realistic 3D simulations of themselves, digital twins to test out ideas of what they might look like in the future.

“We define a smart city as a place applying advanced technology to improve the quality of life for people who live in it,” said Sokwoo Rhee, who’s worked on more than 200 smart city projects in 25 countries as an associate director for cyber-physical systems innovation in the U.S. National Institute of Standards and Technology.

U.S., London Issue Smart Cities Guidebooks

At NIST, Rhee oversees work on a guide for building smart cities. Eventually it will include reports on issues and case studies in more than two dozen areas from public safety to water management systems.

Across the pond, London describes its smart city efforts in a 60-page document that details many ambitious goals. Like smart cities from Dubai to San Jose in Silicon Valley, it’s a metro-sized work in progress.

An image from the Smart London guide.

“We are far from the ideal at the moment with a multitude of systems and a multitude of vendors making the smart city still somewhat complex and fragmented,” said Andrew Hudson-Smith, who is chair of digital urban systems at The Centre for Advanced Spatial Analysis at University College London and sits on a board that oversees London’s smart city efforts.

Living Labs for AI

In a way, smart cities are both kitchen sinks and living labs of technology.

They host everything from air-quality monitoring systems to repositories of data cleared for use in shared AI projects. The London Datastore, for example, already contains more than 700 publicly available datasets.

One market researcher tracks a basket of 13 broad areas that define a smart city from smart streetlights to connected garbage cans. A smart-parking vendor in Stockholm took into account 24 factors — including the number of Wi-Fi hotspots and electric-vehicle charging stations — in its 2019 ranking of the world’s 100 smartest cities. (Its top five were all in Scandinavia.)

“It’s hard to pin it down to a limited set of technologies because everything finds its way into smart cities,” said Dominique Bonte, a managing director at market watcher ABI Research. Among popular use cases, he called out demand-response systems as “a huge application for AI because handling fluctuating demand for electricity and other services is a complex problem.”

smart city factors from EasyPark
Sweden’s EasyPark lists 24 factors that define a smart city.

Because it’s broad, it’s also big. Market watchers at Navigant Research expect the global market for smart-city gear to grow from $97.4 billion in annual revenue in 2019 to $265.4 billion by 2028 at a compound annual growth rate of 11.8 percent.

It’s still early days. In a January 2019 survey of nearly 40 U.S. local and state government managers, more than 80 percent thought a municipal Internet of Things will have significant impact for their operations, but most were still in a planning phase and less than 10 percent had active projects.

smart city survey by NIST
Most smart cities are still under construction, according to a NIST survey.

“Smart cities mean many things to many people,” said Saurabh Jain, product manager of Metropolis, NVIDIA’s GPU software stack for vertical markets such as smart cities.

“Our focus is on building what we call the AI City with the real jobs that can be done today with deep learning, tapping into the massive video and sensor datasets cities generate,” he said.

For example, Verizon deployed on existing streetlights in Boston and Sacramento video nodes using the NVIDIA Jetson TX1 to analyze and improve traffic flow, enhance pedestrian safety and optimize parking.

“Rollout is happening fast across the globe and cities are expanding their lighting infrastructure to become a smart-city platform … helping to create efficiency savings and a new variety of citizen services,” said David Tucker, head of product management in the Smart Communities Group at Verizon in a 2018 article.

Smart Streetlights for Smart Cities

Streetlights will be an important part of the furniture of tomorrow’s smart city.

So far, only a few hundred are outfitted with various mixes of sensors and Wi-Fi and cellular base stations. The big wave is yet to come as the estimated 360 million posts around the world slowly upgrade to energy-saving LED lights.

smart streetlight EU
A European take on a smart streetlight.

In a related effort, the city of Bellevue, Washington, tested a computer vision system from Microsoft Research to improve traffic safety and reduce congestion. Researchers at the University of Wollongong recently described similar work using NVIDIA Jetson TX2 modules to track the flow of vehicles and pedestrians in Liverpool, Australia.

Airports, retail stores and warehouses are already using smart cameras and AI to run operations more efficiently. They are defining a new class of edge computing networks that smart cities can leverage.

For example, Seattle-Tacoma International Airport (SEA) will roll out an AI system from startup Assaia that uses NVIDIA GPUs to speed the time to turn around flights.

“Video analytics is crucial in providing full visibility over turnaround activities as well as improving safety,” said an SEA manager in a May report.

Nashville, Zurich Explore the Simulated City

Some smart cities are building digital twins, 3D simulations that serve many purposes.

For example, both Zurich and Nashville will someday let citizens and city officials don goggles at virtual town halls to see simulated impacts of proposed developments.

“The more immersive and fun an experience, the more you increase engagement,” said Dominik Tarolli, director of smart cities at Esri, which is supplying simulation software that runs on NVIDIA GPUs for both cities.

Cities as far apart in geography and population as Singapore and Rennes, France, built digital twins using a service from Dassault Systèmes.

“We recently signed a partnership with Hong Kong and presented examples for a walkability study that required a 3D simulation of the city,” said Simon Huffeteau, a vice president working on smart cities for Dassault.

Europe Keeps an AI on Traffic

Many smart cities get started with traffic control. London uses digital signs to post speed limits that change to optimize traffic flow. It also uses license-plate recognition to charge tolls for entering a low-emission zone in the city center.

Cities in Belgium and France are considering similar systems.

“We think in the future cities will ban the most polluting vehicles to encourage people to use public transportation or buy electric vehicles,” said Bonte of ABI Research. “Singapore is testing autonomous shuttles on a 5.7-mile stretch of its streets,” he added.

Nearby, Jakarta uses a traffic-monitoring system from Nodeflux, a member of NVIDIA’s Inception program that nurtures AI startups. The software taps AI and the nearly 8,000 cameras already in place around Jakarta to recognize license plates of vehicles with unpaid taxes.

The system is one of more than 100 third-party applications that run on Metropolis, NVIDIA’s application framework for the Internet of Things.

Unsnarling Traffic in Israel and Kansas City

Traffic was the seminal app for a smart-city effort in Kansas City that started in 2015 with a $15 million smart streetcar. Today, residents can call up digital dashboards detailing current traffic conditions around town.

And in Israel, the city of Ashdod deployed AI software from viisights. It helps understand patterns in a traffic monitoring system powered by NVIDIA Metropolis to ensure safety for citizens.

NVIDIA created the AI City Challenge to advance work on deep learning as a tool to unsnarl traffic. Now in its fourth year, it draws nearly 1,000 researchers competing in more than 300 teams that include members from multiple city and state traffic agencies.

The event spawned CityFlow, one of the world’s largest datasets for applying AI to traffic management. It consists of more than three hours of synchronized high-definition videos from 40 cameras at 10 intersections, creating 200,000 annotated bounding boxes around vehicles captured from different angles under various conditions.

Drones to the Rescue in Maryland

You don’t have to be a big city with lots of money to be smart. Seat Pleasant, Maryland, a Washington, D.C., suburb of less than 5,000 people, launched a digital hub for city services in August 2017.

Since then it installed intelligent lighting, connected waste cans, home health monitors and video analytics to save money, improve traffic safety and reduce crime. It’s also become the first U.S. city to use drones for public safety, including plans for life-saving delivery of emergency medicines.

The idea got its start when Mayor Eugene Grant, searching for ways to recover from the 2008 economic downturn, attended an event on innovation villages.

“Seat Pleasant would like to be a voice for small cities in America where 80 percent have less than 10,000 residents,” said Grant. “Look at these cities as test beds of innovation … living labs,” he added.

Mayor Grant of Seat Pleasant aims to set an example of how small towns can become smart cities.

Rhee of NIST agrees. “I’m seeing a lot of projects embracing a broadening set of emerging technologies, making smart cities like incubation programs for new businesses like air taxis and autonomous vehicles that can benefit citizens,” he said, noting that even rural communities will get into the act.

Simulating a New Generation of Smart Cities

When the work is done, go to the movies. Hollywood might provide a picture of the next horizon in the same way it sparked some of the current work.

Simulated smart city
Esri’s tools are used to simulate cities for movies as well as the real world.

Flicks including Blade Runner 2049, Cars, Guardians of the Galaxy and Zootopia used a program called City Engine from startup Procedural that enables a rule-based approach to constructing simulated cities.

Their work caught the eye of Esri, which acquired the company and bundled its program with its ArcGIS Urban planning tool, now a staple for hundreds of real cities worldwide.

“Games and movies make people expect more immersive experiences, and that requires more computing,” said Tarolli, a co-founder of Procedural and now Esri’s point person on smart cities.

Teen’s Gambit: 15-Year-Old Chess Master Puts Blundering Laptop in Check with Jetson Platform

Only 846 people in the world hold the title of Woman International Master of chess. Evelyn Zhu, age 15, is one of them.

A rising high school junior in Long Island, outside New York City, Zhu began playing chess competitively at the age of seven and has worked her way up to being one of the top players of her age.

Before COVID-19 limited in-person gatherings, Zhu typically spent two to three hours a day practicing online for an upcoming tournament — if only her laptop could keep up.

Chess engines like Leela Chess Zero — Zhu’s go-to practice partner, which recently beat all others at the 17th season of the Top Chess Engine Championship — use artificial neural network algorithms to mimic the human brain and make moves.

It takes a lot of processing power to take full advantage of such algorithms, so Zhu’s two-year-old laptop would often crash from overheating.

Zhu turned to the NVIDIA Jetson Xavier NX module to solve the issue. She connected the module to her laptop with a MicroUSB-to-USB cable and launched the engine on it. The engine ran smoothly. She also noted that doing the same with the NVIDIA Jetson AGX Xavier module doubled the speed at which the engine analyzed chess positions.

This solution is game-changing, said Zhu, as running Leela Chess Zero on her laptop allows her to improve her skills even while on the go.

AI-based chess engines allow players like Zhu to perform opening preparation, the process of figuring out new lines of moves to be made during the beginning stage of the game. Engines also help with game analysis, as they point out subtle mistakes that a player makes during gameplay.

Opening New Moves Between Chess and Computer Science

“My favorite thing about chess is the peace that comes from being deep in your thoughts when playing or studying a game,” said Zhu. “And getting to meet friends at various tournaments.”

One of her favorite memories is from the 2020 U.S. Team East Tournament, the last she competed at before the COVID-19 outbreak. Instead of the usual competition where one wins or loses as an individual, this was a tournament where players scored points for their teams by winning individual matches.

Zhu’s squad, comprising three other girls around her age, placed second out of 318 teams of all ages.

“Nobody expected that, especially because we were a young all-girls team,” she said. “It was so memorable.”

Besides chess, Zhu has a passion for computer science and hopes to study it in college.

“What excites me most about CS is that it’s so futuristic,” she said. “It seems like we’re making progress in AI on a daily basis, and I really think that it’s the route to advancing society.”

Working with the Jetson platform has opened up a pathway for Zhu to combine her passions for chess and AI. After she posted online instructions on how she supercharged her crashing laptop with NVIDIA technology, Zhu heard from people all around the world.

Her post even sparked discussion of chess in the context of AI, she said, showing her that there’s a global community interested in the topic.

It’s Not Pocket Science: Undergrads at Hackathon Create App to Evaluate At-Home Physical Therapy Exercises

The four undergrads met for the first at the Stanford TreeHacks hackathon, became close friends, and developed an AI-powered app to help physical therapy patients ensure correct posture for their at-home exercises — all within 36 hours.

Back in February, just before the lockdown, Shachi Champaneri, Lilliana de Souza, Riley Howk and Deepa Marti happened to sit across from each other at the event’s introductory session and almost immediately decided to form a team for the competition.

Together, they created PocketPT, an app that lets users know whether they’re completing a physical therapy exercise with the correct posture and form. It captured two prizes against a crowded field, and inspired them to continue using AI to help others.

The app’s AI model uses the NVIDIA Jetson Nano developer kit to detect a user doing the tree pose, a position known to increase shoulder muscle strength and improve balance. The Jetson Nano performs image classification so the model can tell whether the pose is being done correctly based on 100+ images it was trained on, which the team took of themselves. Then, it provides feedback to the user, letting them know if they should adjust their form.

“It can be taxing for patients to go to the physical therapist often, both financially and physically,” said Howk.

Continuing exercises at home is a crucial part of recovery for physical therapy patients, but doing them incorrectly can actually hinder progress, she explained.

Bringing the Idea to Life

In the months leading up to the hackathon, Howk, a rising senior at the University of Alabama, was interning in Los Angeles, where a yoga studio is virtually on every corner. She’d arrived at the competition with the idea to create some kind of yoga app, but it wasn’t until the team came across the NVIDIA table at the hackathon’s sponsor fair that they realized the idea’s potential to expand and help those in need.

“A demo of the Jetson Nano displayed how the system can track bodily movement down to the joint,” said Marti, a rising sophomore at UC Davis. “That’s what sparked the possibility of making a physical therapy app, rather than limiting it to yoga.”

None of the team members had prior experience working with deep learning and computer vision, so they faced the challenge of learning how to implement the model in such a short period of time.

“The NVIDIA mentors were really helpful,” said Champaneri, a rising senior at UC Davis. “They put together a tutorial guide on how to use the Nano that gave us the right footing and outline to follow and implement the idea.”

Over the first night of the hackathon, the team took NVIDIA’s Deep Learning Institute course on getting started with AI on the Jetson Nano. They’d grasped the basics of deep learning. The next morning, they began hacking and training the model with images of themselves displaying correct versus incorrect exercise poses.

In just 36 hours since the idea first emerged, PocketPT was born.

Winning More Than Just Awards

The most exciting part of the weekend was finding out the team had made it to final pitches, according to Howk. They presented their project in front of a crowd of 500 and later found out that it had won the two prizes.

The hackathon attracted 197 projects. Competing against 65 other projects in the Medical Access category — many of which used cloud or other platforms — their project took home the category’s grand prize. It was also chosen as the “Best Use of Jetson Hack,” among 11 other groups that borrowed a Jetson for their projects.

But the quartet is looking to do more with their app than win awards.

Because of the fast-paced nature of the hackathon, PocketPT was only able to fully implement one pose, with others still in the works. However, the team is committed to expanding the product and promoting their overall mission of making physical therapy easily accessible to all.

While the hackathon took place just before the COVID outbreak in the U.S., the team highlighted how their project seems to be all the more relevant now.

“We didn’t even realize we were developing something that would become the future, which is telemedicine,” said de Souza, a rising senior at Northwestern University. “We were creating an at-home version of PT, which is very much needed right now. It’s definitely worth our time to continue working on this project.”
