GE Crashs

I’m trying to make a simulation of a new robot that I’m designing. Obviously I need physics of my shape, and not box, sphere, cylinder, or other else. But when I put bounds to be Triangle Mesh, Blender seems crash, specially, when I try to move the robot using the sensors. I tried to make various convex hull, make one child of other, and make a compound bound, but crashs again. Somebody can help me? I gonna attach my .blend, if you find some error or how to fix the problem. say me please. IT’S VERY IMPORTANT, CUZ IT’S A PROJECT FOR UNNIVERSITY. THANKS

I forgot attachments, so there is here
