i don't know if anyone's seen these http://www.andymark.biz/am-0619.html

its what my team uses and other teams are starting to use and no complaints

Re: Ball Magnets
 

Mind telling me exactly how that works? It appears as if the arms would just push the ball away...

Re: Ball Magnets
 

here's a picture of our teams bot just for visual aid. http://www.chiefdelphi.com/media/photos/35174

they way we use it is use those rollers to grab the ball then once its grabs the ball it keeps the ball spinning on a igus shaft. works great.

Re: Ball Magnets
 

i guess i misunderstood what you said we just have a roller no pinching systems :/ sorry for the misunderstanding

Re: Ball Magnets
 

Do you have any other pictures of this setup?
Do you press fit them on the igus shft, or do you glue them on?

I bought some of those recently and explained in my earlier post I wish to copy the design.

Re: Ball Magnets
 

Oh... so they are flexible enough that they have a low enough friction coefficient that the ball follows the bar instead of bouncing away?

Re: Ball Magnets
 

They are mounted on a square shaft. The igus is the idler roller.

Re: Ball Magnets
 

actually the " entrappion" stars themselves are on a a tight fit on a 1/2 in square shaft.

if u look at the photo closely we used a 3/4 in igus shaft that is used to not only to keep the ball from going too far in but also to keep the ball spinning on the shaft to have better ball control.
