This is the advanced robot with an acrobatic repertoire of 75 moves that include somersaults, backflips, and playing an air guitar solo. 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. Each action is accompanied by sound effect from its 1-watt speaker. Operates for up to 40 minutes from a three-hour charge of its built-in battery using the included AC adapter. A lightweight, precision-machined aluminum composite frame and injection-molded plastic covering provides a strong frame and exoskeleton. Includes software that works with Windows 7, XP, and 2000 for programming additional actions using the included USB cable. Ages 12 and up. 13" H x 6" W x 2 1/2" D. (3 lbs.)
