World's Smallest Robot With Gripper (http://www.youtube.com/watch?v=uFh9SrXJ1EA&feature=player_embedded#lq-lq2-hq)
This tiny robot uses an 18x Picaxe microcontroller from Sparkfun, a micro serial servo controller, 2 high torque servos and 2 standard servos from Polulu and 2- 1/8? x 1/16? and 1- 1?x1?x1? neodymium magnets (a detailed parts list is available in the link). The case of the robot is built from 3 metal cases made of .oo5? thick phosphor bronze sheet metal and the volume of the robot measures less than 1/20 of a cubic inch. The robot only uses non-magnetic materials in its construction, including the glass bead wheels which are attached to brass pins on the bottom of the robot.
