Finally you can give your drummer his walking papers. Let's be honest, he was the weak link in the band, right? From now on, all your percussive duties can be carried out by this ingenious bot, whose only duty in artificial-life is to roll around, find objects to bang on, and create funky little loops. Basically, the Yellow Drum Machine uses two microphones / sound sensors on its "head" to search out surfaces suitable for rocking, then uses two sticks to play a beat, record it, and accompany the playback. The end result is a surprisingly human -- and wiggle-inducing -- rhythm. Check the video after the break to see just how nasty this robot gets.
