Re: ARM GEARING ON ROBOT
I'm not sure on the torque calculations for our arm (I'm on the drive train team) but for the lower joint of our arm we used two FP motors locked to a common shaft with a 16T sprocket on it. This sprocket "walks" along the OD of a semi circular, .500" thick piece of lexan with #25 chain around the OD seated in a groove. As for the upper joint we have a van-door motor fed through a modified KOP gearbox with a 4 foot (pneumatically telescopes to 5 feet) arm on the output shaft.
