kkleiner writes "In his continuing obsession with all things Lego, robotic, and awesome, Chris Shepherd recently constructed the Lego Quad Delta Robot System, a full working model of an industrial robotics line in a factory. The Lego Quad Delta Robot System has four flexing arms that can move in three dimensions, each equipped with a pneumatically driven gripper. Those arms pick up blocks moving on two conveyor belts marked with special light sensors that detect the block's position and color. The system can move 48 of these blocks per minute. Oh, and the whole darn thing, including the impressive support frame, is made out of Lego!"
