3883 ball grabber prototype
 

Hey guys first time on chiefdelhi, thought I would start out and show you guys our ball grabbing prototype. It actually works really well! Rolling the ball to the roller simulated the robot driving to ball. Tell me what you guys think!

Why did you choose to use surgical rubber fingers? What does that add to the roller?

Re: 3883 ball grabber prototype
 

We did something similar back in 09 but with pneumatic tubing instead of surgical tubing.

It starts to grab the ball before it gets to the roller. The roller is only pvc tube and that wont grab the ball as well. When our robot goes for a ball we want it to be ours.

Why not use tread on the roller to grip the ball?

Re: 3883 ball grabber prototype
 

Its what we had and its seems to be easy on the balls. Why fix something thats not broken?

Re: 3883 ball grabber prototype
 

The fingers also help if you approach the ball rather quickly. Instead of having a solid bar ramming into the ball trying to get a grip, you have things that will be pushing it down and toward the collector.

Interesting idea!!! Keep on working on it!

Thanks for the comments! Hope to show more when we start shooting!

Looking good across town guys! Can't wait to see more!

Looks like I beat SuperNerd So

WELCOME TO CHIEF DELPHI!!!!!!! :)

I like it btw

Re: 3883 ball grabber prototype
 

Like our collector in Breakaway.
If you find the tubing wrapping around the cylinder and causing problems, a few pieces of pneumatic tubing in addition to the latex will help a lot.

Re: 3883 ball grabber prototype
 

may i suggest a paddle wheel kind of thing with the paddles made out of pneumatic hose

Re: 3883 ball grabber prototype
 

Thanks guys for the comments. Any help is welcome. This is why it is a prototype can still try out different variations of tubes, paddles, and any other things. I think we will try some of the ideas on here. Thanks for all the input again!

Interesting mechanism I must say. We are working on something just as that and the added fingers makes this an even better way to pick balls.

We figured that something like this might help us get two or even three balls at a time (depending on their length).
