Here's a fun video of a group of robots performing The Beatles classic song Come Together. They really bring their own sound to the tune.
An explanation from the YouTube description:
Four of Drexel's HUBO robots perform the Beatles' "Come Together" in a demonstration that combines cutting-edge engineering technology and research with creative expression, produced by the Music & Entertainment Technology Laboratory (MET-lab). The HUBOs are operating autonomously (not human-controlled). Their movements are directed by student-developed software to perform the gestures necessary to produce the appropriate notes and beats as dictated by a musical score. Every sound in the video was performed by the robots.
Here's where you can learn more about the robotics at Drexel Univerisity.
