Engineers at Japan’s Saitama University have devised a wheelchair capable of following a caretaker accompanying the patient, eliminating the need for manually carting the wheelchair.

The person accompanying the wheelchair wears a radio beacon that transmits a continuous pulse of signals that are detected by motion sensors on the wheelchair. Using these sensors, the wheelchair follows behind or besides the person guiding it.

Applications are abundant in highly congested healthcare installments where caretakers are required to handle more than one wheelchair simultaneously. The technology can be used to program multiple wheelchairs that can follow a single person guiding them with ease.
