Its 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 its sound sensor hears your command, it reacts; clap your hands or make any other loud sound to control it.

Comet can react to your sounds either by following a sequence of commands (forward, stop, clockwise spin, and stop), or by randomly choosing its next action. Drop a pen in Comet’s pen holder and make it draw!

This robot kit is designed for beginners (recommended age 14 and up) and requires no prior robot-building experience. Only basic hand tools are needed for assembly: diagonal cutter, small hammer, screwdriver, long nose plier, and pen knife.
