Details: As seen in Zwolle recently, there is a new LEGO Mindstorms NXT-based version of Wall-E. This version tries to be strictly purist and true to the NXT system - not only does this not use any third-party robotics components, but this doesn't even use Power Functions motors (unlike the first great Wall-E we covered)! 8 NXT motors and 3 NXT programmable bricks were crammed in here to get this realistic and surprisingly expressive range of motion. While it doesn't transform, it seems to have every other Wall-E behavior down. Color sensors were even used to allow his eyes to light up in different colors. Don't miss the second link above, which has some photos of the internal mechanisms.
