Self-driving wheelchair rolls out at University of Toronto
Working under the direction of Professor Jonathan Kelly, Xinyi is helping to extend leading-edge technology that makes it possible for the wheelchair to navigate and drive itself.
The WiFi-enabled wheelchair is unique because it incorporates low-cost visual sensors instead of expensive laser scanners, making it a much more feasible, near-term solution than similar proposed designs. It operates on the same principles as a self-driving car: an onboard computer provides a geometric map of a user’s surroundings and then the user issues simple commands to travel from point A to point B. The powerchair relies on computer vision technology to avoid obstacles, travel through doorways, and manoeuvre into safe positions. It is currently controlled via a tablet or smartphone.
“Part of the impetus for this project was the fact that we’re seeing so many companies get involved in self-driving cars,” says Professor Kelly, who is the director of the U of T Space and Terrestrial Autonomous Robotics Systems (STARS) Lab. “Certainly a self-driving wheelchair — which moves at much slower speeds — should be a slightly easier problem to solve.”
During her time in Canada, Xinyi is working to determine the best way for users with severe upper-body mobility limitations to command the chair simply and efficiently, using existing sip-and-puff switches or eye gaze technology.
For Xinyi, the experience of coming to Canada is an opportunity to explore a new academic atmosphere and gain the skills she will need to apply for either a master’s or PhD in the future.
“I haven’t decided about a specific career path yet, so my main goal is to perform my best and finish my internship with a scholarship to further my studies,” says Xinyi.
