SDR-4X humanoid robots / dance demonstration / Tokyo, Japan / photographic timeline
SDR-4X can carry on simple conversations with its 60,000-word vocabulary, recognize color, dodge obstacles in its path and even sing once programmed with music and lyrics.
The robot, by Sony, also can be programmed to recognize 10 people through their faces, stored as digital images shot with its camera, and their voices, picked up through seven microphones. It also will remember their names.
In a demonstration, the robot sang in harmony, shaking its hips and waving its arms in tempo. It also balanced itself on a surfboard tilting at various angles.
