How did you guys use your 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 used a Fisher Price to control our second arm joint.
We use our FP’s to extend and retract on our 11.5 foot arm. Both FP’s and their gearboxes turn a spindle that winds and unwinds spectra cable. We can get the arm all the way out in about …4-5 sec.

Here is a good pick of the arm and its FP’s.

Team 716 used used one FP motor to drive the joint of our secondary arm.

We combined the FP gearbox and the kit gearbox together to create the proper reductions needed to lift the tetras. So far it works wonderfully. The FP barely even gets warm each time we run it. While I wouldn’t say it is the most compact arm joint out there, it does the job well, especially for the first time our team has ever attempted to build a complex arm (well, more complex than anything we have done in the past).
Come check it out at UTC, New Jersey, or nats.

edit: I found some pictures of our arm setup; one is a picture of the KOP gearbox with the drum from the FP gearbox attached, the other is a picture of the FP and its gearbox. The two are put together and…voila!
yea, one of the mentors found some couplers that used to be on an old barbie jeep and we used them for the bot.
How did 1293 use the FP motors?
We used it to add to the mass of our box of motors. 
We used 2 of those babies to power our main arm. Both are coupled into a shared shaft, which has a small sprocket attached. That sprocket then sits on a fixed chain “roller” system. While it may add a little weight, it saves us the frustration of chain tensioners. It also makes for easy swap on/swap off of motors and sprockets.

I dont care what anyone says, the FP motor is one of the best in the kit!
We didn’t use them. As a matter of fact we gave them to Tom^ since we have no plans for them.
We only used the FP one year, 2000, to drive a belt and that was it.
We used the Fisher Price motors to freshen our shop with a plasticy fresh scent and warm our hands when it was cold outside.
haha
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.
