Re: WHich motor to lift and for arm

I would suggest that you look in the White Papers technical section for the papers on motor selection. Ken Leung has done a nice job of compiling info from Joe Johnson and others that will let you select a motor and gear ratios to keep from smoking motors. The key is determinig the Power you need first and then adjusting the motors to get the required torque.

The examples can be used as 'recipes' for lifting balls and robots. We used these notes this past year to select dual Fisher Price gearboxes to lift twice the weight of our robot straight up in under 10 seconds. We have not tested the twice the weight yet but it gives us a good safety factor.
