Re: Banebot Transmission Issues

One think I should have mentioned in my "DON'T PANIC" message above is that if you designed the gear ratio of your arm/mechanism right in the first place, you are probably never going to see any problems.

I have recommended that teams design the ratio such that the highest "normal" load the arm is expected to put on the motor would be 1/5 to 1/4 of the stall torque. This is good practice for a lot of reasons, but to my usual reasons I can now add one more: The Banebot Transmission will not see anything like the stall torque of the motor (assuming your don't run your arm into end stops or the ground or whatever).

For what it's worth.
