If it makes you feel any better robots get old too.

Just like humans their joints begin to fail, and certain abilities fade or become less reliable over time. The difference (besides complaining about it) is humans naturally adjust or adapt their movement to compensate for decline.

Robots aren’t quite there yet, but research made possible by support from the National Research Council (NRC) is helping University of Waterloo researchers learn how the human brain processes decay over time, what adjustments it makes, and how that can help robots manage fading sensors and overworked joints as they wear down.

“Figuring out how our brains process declining movement involves an incredible amount of computer simulations,” says, Terry Stewart an NRC Associate Research Officer at Waterloo. “These simulations have helped us create a biological representation of how the human brain might manage decline and given us a pathway to apply that to intelligent machines.”

Stewart and his team hope that this knowledge, combined with machine learning, can provide Canadian manufacturing with tremendous benefits and efficiencies.

“Let’s say a robot in a manufacturing plant performs the same function many thousands of times a day. Regular wear and tear can lead to that machine making mistakes. Even if it’s just a millimetre or two off, that can compromise its work.” says Stewart. “But if it can understand and predict that decomposition as it’s happening it can modify its motion.”

That project is just one of a host of NRC-sponsored projects underway at Waterloo making breakthroughs in artificial intelligence, the internet of things and cybersecurity.

Those projects include:

Automated Material Synthesis using Deep Reinforcement Learning

This second round of funding was reaffirmed by NRC President Iain Stewart as NRC and Waterloo come together on the development of five new upcoming projects, with Waterloo supplying matching funds bringing the total dollar amount to $900k. Those new projects will be decided on and announced March 31st.

The NRC and Waterloo Collaboration will help position Canada as a global leader in these future-relevant areas and aid the NRC is its mandate to increase its collaboration with regional ecosystems like the one that exists in the Region of Waterloo and universities like Waterloo.

“The work being done thanks to the generosity of NRC is going to keep Canada at the top of the pile of universities on the cutting edge of technological research,” says Terry Stewart. “Advancements being made in our labs today will hopefully soon be deployed in Canadian Plants, homes and infrastructure to make our society more innovative and resilient.
