Re: 816's Robot as of 2/2/08
nice and simple, can you guys knock off the ball?
|
Re: 816's Robot as of 2/2/08
yeah we actually can either knock it off with the forks on the elevator or we drive under the overpass and put the elevator up and just push the ball off the top.

I like the tennis balls! We need some sort of plugs for the end of our picker-upper, and this thought never occured to me.
Looks like a nice reliable design. How quickly can you move the ball over the overpass? |
Re: 816's Robot as of 2/2/08
I like the tennis balls too, A mentor on our team ordered some orange and blue balls from a school supplier. It takes about 10-12 seconds to move the ball up and about 20-30 seconds for a full hurdle. I might get some video up in the coming week maybe late monday or tuesday.

Re: 816's Robot as of 2/2/08
Very nice gripper and elevator. I get this weird feeling, though, that an abrupt stop or a bump from behind when you're in the configuration in the first picture would send you over... does it feel tippy at all? Also, what's your distance from left tennis ball to rear right corner right now?

How are you hoisting your uprights? Are you using chain? If so, how are you doing it? Any pics available? We are having difficulties with ours and we can sure use some help. Yours sure looks wonderful.:) We have looked at webbing, cable, chain. We are not sure how to proceed.:confused:

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. |

Re: 816's Robot as of 2/2/08
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.

Re: 816's Robot as of 2/2/08
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

Re: 816's Robot as of 2/2/08
I like those tennis balls but does this bot shoot?
|
Re: 816's Robot as of 2/2/08
Nah we pick it up and put it over. =)
|
Re: 816's Robot as of 2/2/08
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 |
Re: 816's Robot as of 2/2/08
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.
