It's snail-like design may give a lethargic impression but, contrary to first impression, COMET is quick to respond and scurries speedily on command. A condenser microphone and a printed circuit board control this OWIKIT. Each time it's sound sensor hears your command it reacts. COMET possesses three radical features: sequential command, random control, and drawing capabilities. The two-wheeled mechanical marvel can be controlled in its sequential mode. Clap your hands or make any other loud sound to control it. For each sound COMET will begin a new action. The sequences of commands are: forward, stop, clockwise spin, and stop. Random control allows COMET to make it 's own movement decisions. Drop in 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!
