One good reason is because they already have four CIMs on their drivetrain. However, a Fisher-Price with an AM planetary could do almost as well.

What kinds of speeds does the FP motor do. They said above that the Van Door takes 10-12 seconds to raise or lower. We wanted to know if the FP or RS550 are faster? Does anyone have any specs on these?
How fast would the Fisher Price with AM planetary be?

I'm not sure for this system, but on 330's cable lifts, as much as five seconds for a similar height, after running them through a stock FP gearbox. It would be a good idea to "gang" two FPs to aid in power. Unfortunately, I am not sure where the specs for them are...

I saw "2 CIMs through KoP gearbox" and figured one per side, cause why go for extra drive power in a non-pushing game?

Anyways, FP through an andymark planetary in this application is a recipe for disaster unless you run it through a dewalt as well. I think they pretty obviously need the anti-backdrive ability. If you're running it through a dewalt anyways, go straight into the dewalt, I think. Also, you'd be wise to be careful with the FPs as they can be overheated and smoked.

We have 4 cims already on the drive train. We do need the anti-backdrive ability and are quite confused by the different opinions of the other motor options. How are we suppose to choose?

Nice,
I was wondering how you did your drive ststem and how fst your bot can do a lap?

Re: 816's Robot as of 2/2/08
 
Lol I sleep for one night and come back to find a bunch of replies. The reason we didn't use a Cim was because we already are using all 4 on our drive train, And the van door motor works great for our application. Lapwise we should be able to do one in about 10-15 seconds without the ball, but that's just an estimate because I didn't really have any space to open up the robot because right now we only have one piece of carpet down.

Very nice! :P I was wondering does it fold in via programming or do you have to fold it in manually?

Re: 816's Robot as of 2/2/08
 
how much strain are the motors put under just lifting the ball?:confused: i know with previous experiance, that even a little bit of wieght away from the base can make it very hard to lift.

Re: 816's Robot as of 2/2/08
 
We can control everything via the Operator Interface there's really no complex programming to do just a few limit switches. Lifting the ball for us it not a problem we have plenty of power to spare. If we wanted to we could make it lift a little faster but we probably won't

I like those tennis balls but does this bot shoot?

Nah we pick it up and put it over. =)

I agree that this bot looks sexy but I have a fealling you might have a problem with the chain we ran into that problem with a telescoping front arm like that

if you dont have problem thats good

We have been driving it for almost two weeks now. At first we had some chain problems but we managed to fix them. And ever since works like smooth.
