Quad Track: IR-Ball Seeking Crane    Send article as PDF   
This is my LEGO Mindstorms NXT Quad Caterpillar Track Crane, which uses my ‘Ultimate Grab‘ to pick-up and retrieve a Hitechnic Infra-Red Electronic Ball. The Chassis houses 2x NXT Motors to drive the Left and Right pairs of Tracks. A third NXT Motor is used to raise and lower the crane arm. A Small PowerFunctions Motor is used to open and close my Ultimate Crane Claw attachment. The Small PowerFunctions Motor is controlled via a Mindsensors Multiplexer for NXT Motors (NXTMMX-v2). The NXTMMX allows the NXT to control two additional NXT or other LEGO Motors.
