NeveRest 60 in FRC

With the widening of the servo rules you could get a similarly powerful servo and not have to purchase another motor controller.

We may be biased here at AndyMark, but we think it has been a net positive for FIRST Tech Challenge teams.

I think this post is a lot of words saying "My name is Billfred and I approve MiniBots 2017"

They saw very little usage. I saw a couple used for infeeds for shooters, a couple other folks tried to gear to do shifting because they were more powerful than the servos allowed at the time if I recall correctly.....

Us and 33 used them for shooter angle adjustment.

I was more going off of that minibots were made of FTC parts in general, although, I guess the definition of "FTC parts" has expanded quite a bit since 2011.

Cothron... 3481 Bronc Botz in 2012 designed our shooter hood to adjust angles with VEX 393's driving VEX lead screws but then FIRST ruled that adding the optional VEX 393 integrated encoder constituted a motor modification (was a completely baffling decision) and we had to scrap that approach and go with a fixed hood and variable speed on the flywheel shooter.

Not a insurmountable problem but the 5V bus current limits you regardless of the rules. As a personal thing I try not to put motor loads on a controls power bus anyway.

Isn't that closer to a gearbox modification though? Did they also ban the Turbo gear set?

Oooops.... We ran them all year.

Same speed and similar power to a window motor, with an encoder - yes, we've had an application most years where this would have done the trick. At least twice we've had parts which we needed to deploy outside of the frame perimeter at startup, but that were then held in place with a latch or gravity, and several internal feeders and game piece controllers for which this would be a great fit. At $28 or 20 FC points each, they're also a fairly inexpensive encoder, even if you don't use the motor. And hey, they already have power poles installed if you do!

I don't have test data on this motor, yet. As the one who published data on the 2011 Minibot motors (aka smoke generators), I believe that the new motor is a significant improvement; this is based on a visual inspection of an early sample motor at Andy's desk during a visit to AM a few months ago, and on review of the data furnished by the motor manufacturer. I expect the Andymark engineers will be publishing their own test results soon. We should all suspend judgement about the NeveRest 60 for a while -- AM data will go a long way toward building my understanding of its real capability, and of course a season of in-situ performance will go even further.

All that said, there is data already available on the AM site. And that data supports what Billfred said above.

I'm pretty sure I've seen some turrets driven by a 393 motor in 2012.

Motions that didn't require much power. I think I remember 11 using it to push frisbees into their shooter.

All the NeveRest 60 discussion in the FIRST Choice thread is now part of this thread, in the name of good thread hygiene as suggested by a user.
