Check out this is acrobatic robot! The robot has a repertoire of 75 moves that include somersaults, backflips, and a variety of comical moves.
From the Advanced Acrobatic Robot description:
With a 60 MHz microcontroller, the robot has 17 servos that work in unison with an included gyro sensor and accelerometer to maintain balance and stability while providing lightning-quick movements that suggest humanoid sentience, commanded by an included wireless gamepad remote control. The points of articulation in its neck, arms, hands, legs, and feet are so precise that the robot can be commanded to pick up and hold objects with its hands, feign a soccer kick, or punch the air as if it were performing a martial arts kata-it can even bow to its audience after a performance.
The robot comes with software that works on Windows 7, XP, and 2000 allowing you to program additional actions via an included USB cable.
