Re: Climber help: thermal breakers.

On the 1.25in roller we are playing to use that ends up giving us a solid climb speed of about 7.5 seconds. CAD suggest that our worst case would be a 100lb robot. Across each breaker that would be 40.48amps assuming a gearbox efficiency of 90%.
Your ratios are what concern me. You should be able to make a sub-5s climb with a single 775Pro, a fully weighted robot, and more aggressive reduction. Have you used the JVN calculator to determine your speeds?
