Like so many software developers, Elias Sorensen has been studying AI. Now he and his 10-member team are teaching it to robots.
When the AI specialists at Mobile Industrial Robots, based in Odense, Denmark, are done, the first graduating class of autonomous machines will be on their way to factories and warehouses, powered by NVIDIA Jetson Xavier NX GPUs.
“The ultimate goal is to make the robots behave in ways humans understand, so it’s easier for humans to work alongside them. And Xavier NX is at the bleeding edge of what we are doing,” said Sorensen, who will provide an online talk about MiR’s work at GTC Digital.
MiR’s low-slung robots carry pallets weighing as much as 2,200 pounds. They sport lidar and proximity sensors, as well as multiple cameras the team is now linking to Jetson Xavier GPUs.
Inferencing Their Way Forward
The new digital brains will act as pilots. They’ll fuse sensor data to let the bots navigate around people, forklifts and other objects, dynamically re-mapping safety zones and changing speeds as needed.
MiR chose Xavier for its combination of high performance at low power and price, as well as its wealth of software.
“Lowering the cost and power consumption for AI processing was really important for us,” said Sorensen. “We make small, battery-powered robots and our price is a major selling point for us.” He noted that MiR has deployed more than 3,000 robots to date to users such as Ford, Honeywell and Toyota.
The new autonomous models are working prototypes. The team is training their object-detection models in preparation for first pilot tests.
Jetson Nano Powers Remote Vision
It’s MiR’s first big AI product, but not its first ever. Since November, the company has shipped smart, standalone cameras powered by Jetson Nano GPUs.
The Nano-based cameras process video at 15 frames per second to detect objects. They’re networked with each other and other robots to enhance the robots’ vision and help them navigate.
Both the Nano cameras and Xavier-powered robots process all camera data locally, only sending navigation decisions over the network. “That’s a major benefit for such a small, but powerful module because many of our customers are very privacy minded,” Sorensen said.
MiR developed a tool its customers use to train the camera by simply showing it pictures of objects such as robots and forklifts. The ease of customizing the cameras is a big measure of the product’s success, he added.
AI Training with Simulations
The company hopes its smart robots will be equally easy to train for non-technical staff at customer sites.
But here the challenge is greater. Public roads have standard traffic signs, but every factory and warehouse is unique with different floor layouts, signs and types of pallets.
MiR’s AI team aims to create a simulation tool that places robots in a virtual work area that users can customize. Such a simulation could let users who are not AI specialists train their smart robots like they train their smart cameras today.
The company is currently investigating NVIDIA’s Isaac platform, which supports training through simulations.
The journey into the era of autonomous machines is just starting for MiR. It’s parent company, Teradyne, announced in February it is investing $36 million to create a hub for developing collaborative robots, aka co-bots, in Odense as part of a partnership with MiR’s sister company, Universal Robotics.
Market watchers at ABI Research predict the co-bot market could expand to $12 billion by 2030. In 2018, Danish companies including MiR and Universal captured $995 million of that emerging market, according to Damvad, a Danish analyst firm.
With such potential and strong ingredients from companies like NVIDIA, “it’s a great time in the robotics industry,” Sorensen said.
