Re: Fisher Price Gear Box Problem
We're using a banebots 26:1 planetary gearbox running off an FP to a 2" diameter roller with roughtop tread on it. It might be just a touch slow... we're going to work with it on our practice robot to try and optimize it.

When the ball is in "full backspin", we draw about 3-4 amps on the FP... which doesn't drop all that much when there is no ball in the system, so I'd have to say that the force requirements to put backspin on the ball (at least in our stationary testing application) are fairly minimal relative to the gearing and frictional losses.

I hope that provides some useful comparison data. Good luck getting it up and running smoothly. Hooray for the witholding limit!
