Invite Rocks and Robots to your child’s next birthday party and make it a Robot-Sumo party. No previous experience with robots is necessary; and they can accommodate a multitude of skills. Children will learn basic computer programming skills and use light, touch, and sound sensors to make their robot react to its environment. Children are encouraged to prepare their own robot and compete in a Robo-Sumo championship. Lego Mindstorms Nxt: This robot is perfect to introduce little ones to the ever-growing world of robots.
