Scuttling mechanical robotic bug that reacts to touch and sound - from Hexbug.
This fun 6cm micro robotic creature crawls around on his six legs sensing objects in its path. The beetle will travel in a straight line until it bumps into an object with its sensor feelers. Upon contact, the bug reverses in a half circle, then moves forward again in a new direction. Reacts to sound too, just clap your hands to make the Beetle change direction and watch as it scurries away. Fun.
