This monster Lego sorting robot, built by Kenneth and Lasse of BrickIt, organizes bricks by size as well as color. It uses 28 motors, 7 NXT microcontroller bricks, 7 muxes, 22 sensors, and 37,500 Lego elements total. The NXT bricks communicate with each other via bluetooth and are programmed in leJOS, a Java-based firmware replacement for NXT-G, the noob-friendly but less powerful environment NXT ordinarily ships with. (The model was created as a promotion for a company called Dynaway, hence the name-dropping in the video.) [via the NXT Step]
