Motorized LEGO tank looks menacing

LEGO is such a wonderful toy for you to play around with, tickling your imagination in the process. Martijn “Dino_Martino” Hellemans of NXT STEP Mindstorms blog fame has been hard at work on a new motorized LEGO tank that is sophisticated beyond your regular Mindstorms creations, where a MTRMX-Nx multiplexer is used to control both NXT servos and Technic motors. Not only that, the entire thingamajic will roll around on tank treads, while there is a LEGO guns-style “high velocity brick cannon” that aims using a laser. This is clearly a labor of love, and we do hope to see more creative LEGO creations come out in the future. What’s the most creative thing you’ve done with your set of LEGO to date?
