How did you use the FP motors?

I drew up a quick CAD diagram of how we did. We were so busy with the bot that we didnt have time to take pictures. Green is the FP motors, red is the winch spindle and blue is the cable. We used a 20" nested ladder.

Tell me what u guys think?

We have a similar configuration.

We used the Fisher Price motors to freshen our shop with a plasticy fresh scent and warm our hands when it was cold outside.

We actually didnt use them this year. We only needed 5 motors, 4 CIMs to drive, window motor for our pulley to raise our arm.

How did we use the FP motors you ask?

Actually, those were toasted and later replaced with 12V's. Our arm runs on dual FP's with gearboxes and a ~16:1 sprocket reduction for extremely high torque. (~400 ft.-lbs. at max efficiency?)

1089 didn't use any FP motors.

234 used ours to lift our arm.
we also had to use the 12V motors.

We used 2 of them to winch up our arm. We can fully extend it in about 3-4 seconds (15 ft).

We didn't need them, we thought of using them but we went with a window motor instead.

We used an FP motor for the first time this year, to power our ball screw extension.

They power our arm.

469 decided to use their Fisher-Prices to power the winch- a critical element for raising and lowering our arm. They are coupled on opposite ends of a single shaft that carries a worm. It's speed is then reduced through a worm gear reduction (1:30) which rotates a drum to collect or release cable. I do not have pictures of it, but you can see it in action at Great Lakes, Detroit, and Atlanta.

FP's are being used to rotate our bumper/secondary drive system and to drive the wheels on the secondary drive system.

To power the bottom two joints in our arm. The lowest is fp on DeWalt 15:1 driving a 20:1 worm driving a 19 to 92 tooth #35 chain 92 tooth drives the arm. Total ratio is 1452:1. Next is fp on DeWalt 15:1 to (20:1 worm has to be assembled at buckeye) then 30 to 135 in #25 arm walks around the sprocket. Total is 1300:1. Tried to use fp at 47:1 and 11 tooth to 135, (567:1) too aggressive and has issues with anti-back drive pins, may have let some smoke out of the motor, good thing we are coming with spares. At least there is less work to be done this year compared to last. We are limiting the fp's to 9 volts RMS in software. Last joint is jidico and globe directly linked on a 19 tooth driving a 135 in #25 chain. (987:1 if you start with the globe). Crossing our fingers and hoping our scale was off by at least 5 lbs.
