[ROB at RAGE]

File Cards were avialble from Small Parts, the had great grip on the carpet. Team 71, who we picked to go alll the way with at the nationals, had them attached to a walking mechism that had two feet which inched the machine foward with one foot and then the other.

We expermented with them to use as an ankers, they had a coefient of friction of like 1.6 to 2, but came to relization that you needed a very low center gravity machine or you were at a big risk of being tiped over. To be honest the only reason that we didn't add them was the added weight and time run out.
