Introducing, Hexbugs,  the colorful little robots that react to sound and have their own object sensors. They run on a tiny battery and can respond to handclaps and steers clear of objects all by itself. They are intelligent little insects.  When the bug bumps or touches something or hears a voice or sound, it stops or reverses direction. Besides being cute, the robotic insects were recipients of iParenting Media's Best Products of 2009.
