Self-Propelled Drum Machine
This awesome robot comes equipped with drumsticks, and uses ultrasonic sensors to navigate around obstacles and seek out an object to beat on. The bot even records the audio of its performance and samples this into future performances.
Built by a guy named fritsl, the bot cost $120 to build and runs a long time on four AAs -- "I just know that it runs for hours, more than my wife can stand to listen to," fritsl said. There is a thorough write-up on letsmakerobots.com.
