Working Model Factory Made With Lego Robots

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!"

    1. Re:neat by peragrin · · Score: 1

      definitely neat. what I found most interesting is that he programmed the color sensors in fixed locations. each arm always goes to the exact same physical spot for a block pick up, it then moves tot a different bin based on color, goes to the reset spot and picks up the next block that enters it's pickup spot.

      Since each arm only picks up blocks in a certain location you would have gaps on density of blocks. However 4 arms provides something like 80% pick up ability so all he needs is a 5th arm so he never loses a block off the end(based on current belt speeds)

      Still it is impressive if not very quiet.
