Drum Machine Robot

This unique little robot roams around looking for objects. When it finds one, it drums on it, samples the sound, then breaks into a pretty catchy rhythm using that new sound. The robot can also detect foot stomping or hand clapping and adjust its tempo to match it. According to the website, the materials cost about $120 and it took 5 hours to create. The builder made very clever use of commonly available items, even the wood from a cheese container! Powered by just four AA batteries, the robot remarkably uses no servo motors, and reportedly runs a very long time. Very clever! And as you'll see on the video, it can be quite addictive!
