Build your own two-wheeled mechanical marvel. Comet is quick to respond and scurries speedily on command. With a condenser microphone and a printed circuit board, Comet's sound sensor hears your command and reacts. Clap your hands or make any other loud sound and Comet will begin a new action. Random control allows Comet to make its own movement decisions. Drop a marking pen in Comet's pen-holder, and command it to draw! Building, controlling, and drawing make Comet a great hands-on learning experience! Suitable for children ages 14 and above.
