Researchers at Japan's Saitama University Human-Robot Interaction Center have invented a robotic wheelchair that will follow your companion or caregiver as you sit back and enjoy the ride.
Using a standard wheelchair, modified with a special camera and laser distance sensor, the chair is able to follow a companion from either the rear or the side, and has the ability to navigate narrow corridors. The wheelchair is currently being tested in various care facilities with hopes to make the invention commercial in the near future.
