Re: 2.5" CIM Motor stops when climbing
To sort of cut through what has been posted -- a single CIM has PLENTY of power to execute a robot climb in a very few seconds. The key factors are -- did you gear down enough so that you can wind up on your drum diameter? How much will your effective drum diameter increase as your rope wraps on top of itself? As a reference point, 3946 is planning to wind some 3/8" line on a 1/2" shaft with a 12.75:1 reduction. Our biggest problem appears to be keeping the rope centered on the robot. Larger diameters will require more aggressive gearing, but will be less susceptible to a wrap or two of line.
