Shooter motors?
 

What motors did you use on your shooter? I was surprised to see many teams using the minbike and normal CIMS up at the top of their robots. We used the FPs, with a BaneBots 1:5 gearbox to get the power we needed for a lot less weight. We avoided the minibike CIMS at all costs, since they weigh ~5 pounds apiece :eek: (If I remember correctly).

Re: Shooter motors?
 

We did the same. I'm very satisfied with the performance of the BaneBots 5:1 gearbox -- thanks again to Joe Johnson for sharing this great find with the CD community.

We wanted to use our FP's for our pickup rollers, so we went with the smaller CIM's with good results.

Re: Shooter motors?
 

Team 1640 did the same...although our results were not as good as we expected (but it was due to things other than the motors). However, we did manage to cease up one of the CIM's we used on our shooter :rolleyes: .

Re: Shooter motors?
 

Wow, how did you cease them? Was your chain too tight, or bad bearings on one of the rotating components?

Re: Shooter motors?
 

Who knows...the motors directly drove the Skyway wheels we used to launch the ball. Here are some pics:

Sweet guards! What did those colanders cost you, about $1.69 each?

Re: Shooter motors?
 

I believe they were $0.88 each...cheap, light, and simple! We always check Wal-Mart when looking for ideas for robot parts.

We used both minibike motors on Chomp's shooter. Shot fine for us (and we shot relatively low, which kept us from tipping most of the time).

Re: Shooter motors?
 

The 2 minibike CIMS combined with a closed velocity loop on the wheel keeps the cycle time very low, and the CG very high.

Re: Shooter motors?
 

One FP motor with a custom gearbox and a chain. Works rather well, and it weighs practically nothing. We originally used the minibike motor to drive our conveyor belt, but the thing weighs more than 5 pounds, so we geared down a FP for that too. Even with the gearbox it weighs several pounds less, and works just as well.

We used the 2 minibike motors on Magnum's Shooter.

Re: Shooter motors?
 

we used 2 small CIM's, mainly because it lets us shoot a continuous stream of balls without the wheel slowing down enough to matter between shots.

Re: Shooter motors?
 

We used one bike CIM because... well, to be honest I had next to nothing to do with our launcher, I spent my time on the drivetrain and such. Part of the reason is because I used 4 CIMs in the drive, and still almost nobody believes me when I tell them how strong the FP is. (And they're worried it'll burn out)

Re: Shooter motors?
 

we used a small cim direct coulpled to and probably 5 pound shooter wheel so we it go up to speed it wouldn't noticably slow down and we have a high rate of fire

Re: Shooter motors?
 

Same here.

Re: Shooter motors?
 

We used both of our CIM minibike motors because our 14" urethane wheel was extremely heavy. >.>

Re: Shooter motors?
 

2 small cims here also. I am surprised that so many teams used the mini bike motors for their shooters. Is this because the "kit" transmissions use the smaller cims?

Re: Shooter motors?
 

We used the minibike motor, mainly because we had already used the cims and no gearing down was required. It was quite simple actually. It worked extremely well for us.
