The Terapio is an omnidirectional robot, developed by researchers at Toyohashi University of Technology, that is designed to replace the medical carts you see being trucked around by doctors and nurses in hospitals.
The robot is equipped with a special tracking mode that allows it to visually track the person that it is designed to assist. This allows it to autonomously follow them whilst also avoiding obstacles. For more precise positioning, the person can manually control the robot via its Power Assist mode. To do this, they simply push a ring-shaped handle. The robot responds by moving itself in the desired reaction.
The Terapio is likely to be seen following doctors and nurses in hospitals in Japan and possibly elsewhere in the years to come.
