NewScientistTech has an article on Keepon, the robot that can dance (for real!).
This squishy, yellow robot picks out the beat in a piece of music and moves along in time. It can also visually detect motion of a person or object and dance in the same rhythm.
Cycling ’74 Max/MSP is used for beat detecting, enabling the robot to dance perfectly to the beat!
Keepon’s ability to pick out the beat in a piece of music makes it fundamentally different to the dancing Qrios, which are entirely pre-programmed. “The important thing is that Keepon is capable of detecting rhythm,” says Fumihide Tanaka, who heads the Qrio Project at Sony Corporation in Tokyo, Japan.
