Let's Make Robots!

belt track friction

I have bought the treads and wheels from MUTR,  the same ones as used in Fritsl's first robot. I have assembled a robot base using the treads and wheels, and two MFA multiratio gearboxes. the robot goes fine in a straight line, but the tracks have too much grip when it needs to turn. I have tried tape, but it makes the tracks too tight. coating the treads with correction fluid gives some improvement, but still not good enough to turn smoothly.

does anyone else have ideas that have/might work?
