View of the interface that animates Roboy, a humanoid robot developed at the Artificial Intelligence Laboratory of the University of Zurich, at the 2014 CeBIT technology trade fair on March 9, 2014 in Hanover, central Germany. Standing at 1.2 m (3.9 ft), Roboy is designed to have the appearance of a child and to one day be used as a helper robot for the sick and elderly. Unlike more traditional robots, which have motors in their joints, Roboy is a tendon-driven robot, allowing for more fluent, human-like movements.
