Researchers at the Human-Robot Interaction Center of Saitama University in Japan have developed a wheelchair that tracks and follows ambulatory companions. Sensors gauge the distance and direction of a walking person's shoulders and moves the chair so that it keeps close. When sensors detect a crowded area, it moves behind the walking companion to avoid blocking the paths of other pedestrians. It's hoped that this design will help ease the workload of people providing care for wheelchair users.
