This robot was inspired by a robot that was granted tons of attention, called the Yellow Drum Machine, I will link to it later when I can find it. This robot uses tank treads to roam around, it uses its ultrasonic sonar to find impediments, It will determine the hardness/softness/echo of an object with sonar. Once it finds an object worth playing on, it will snake into place, then, using motorized drumsticks, make a short 20-60 sec. beat. Using an external recording/playback module, it will record 20sec of the beat, and play it back in sync with the continuously playing beat (with the robot still playing). Upon completion of this minute long jam session, it will roam away, and attempt to find another, in an endless loop. Very fun to watch/listen!
