i am almost positive that that has more than 4 motors
because at the 20sec mark, you can see that there is 4 cims at the corners of the tranny, and therefore those additional tensioners on the top and bottom of the motor pic must hold FP motors.
at nationals i heard them talking about a CVT tranny
i hope this is the case
cus that would be amazing.
BTW, your robot is incredible.
