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 used them in our six motor drive train (http://www.chiefdelphi.com/forums/showthread.php?t=35266)

we do too! 461's six motor drive train (http://www.chiefdelphi.com/forums/showthread.php?t=35199&highlight=461)

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. (http://www.chiefdelphi.com/forums/showthread.php?threadid=35622)

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!

[Validius]

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. :D

[Tom Bottiglieri]

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!

[Jay H 237]

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 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.

[Lil' Lavery]

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?)

[C.Roberts 1089]

1089 didn't use any FP motors.

[crazykid234]

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

[Brandon Holley]

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

[David Guzman]

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

[CyberWolf_22]

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

They power our arm.

[Alex Golec]

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.

[meaubry]

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

[Biff]

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.

[Doug G]

We used two FP's to power our 5 foot arm to pick up tetras. We made a custom gearbox to give 270:1 reduction and then a 9 tooth sprocket to a 60 tooth sprocket to gives a total reduction of 1800:1. It works very well so far, even with limiting in programming to 9.6 Volts. We'll replace them with the 12 V motors at competition in a few days - and be very well set.

Here's a pic of them ... (http://www.chiefdelphi.com/forums/attachment.php?attachmentid=2907)
