This is a Lego Mindstorms NXT robot I build from the “Tilted Twister” instructions. All the pieces are from Mindstorms NXT 1.0 and I bought a extra color sensor from Hitechnic. Me and my dad needed to edit the program a bit so it would recognize the new sensor and we tried several different cubes before we finally got it to work. The model was designed by Hans Anderson and instructions are at http://tiltedtwister.com/download/tiltedtwister/instructions.html
Hope you like it!
