This is the kit that teaches children about robotics and mechanics by building a robot that can jump. The colorful creature has clawlike hands and an otherworldly blue helmet, and most importantly a central spring and two snail-shaped cams inside each arm. When the robot is turned on, the cams rotate and compress the spring; when the spring releases, the ’bot bounces off the ground, delighting kids while illustrating the concepts of potential and kinetic energy. The engaging kit’s 98 pieces also form seven other motorized masterpieces, including a carousel and a kicking machine. The illustrated manual gives clear, step-by-step instructions and explains the scientific principles at work. Requires two AAA batteries. Ages 8 and up. 14 1/2" H x 11 1/2" W x 3" D. (1 3/4 lbs.)
