This little robot is tough! Run using a single motor, he walks with a decidedly "angry" pace and if he falls over, he picks himself up again! An awesome design with an amazing gear mechanism, he will not quit! A big hit at the International Robot Exhibition. An easy build to boot. Features: Easy to build in less than 1 hour - Complex motions from a single motor and 3 modes: Fall and get up mode - dance mode - somersault mode - High impact plastic construction. Requires 2 AA batteries (not included). For ages 8 and up.
