Re: Fisher Price Motors

If you use a PID loop to control the arm, it will be able to dynamically control the motor to hold the arm steady.

Look up PID in the whitepapers section or google it.

Re: Fisher Price Motors

Additionally, you can set the "brake" jumper on the victor speed control, which will slow the rate of descent of your arm a little bit. However, if true non-backdrivability is what you want, a traditional way of achieving that is with a worm gear, like this. The Fisher Price motor (by itself) is a very high RPM motor though, and you'd probably want an additional stage of gearing in there somewhere. Also check out the FIRST mechanism library
