Funneling Balls

How is everyone thinking of funneling their balls into the small space we are allotted in front?

Re: Funneling Balls

Which small space? The alley? The key? What?

Re: Funneling Balls

I think he means the front of the robot, by deploying a 14" funnel appendage. It is definitely an interesting idea, and something we could put in our withholding allowance if we had any extra weight.

Re: Funneling Balls

Our bridge tipper doubles as a collecter. There's an angled plate on each of the arms (connected so it's one) and they funnel in balls. It'll help during hybrid mode when we go to tip the bridge for the extra balls.

Re: Funneling Balls

Yeah, I meant the front of the robot. Our front is 27" wide, and subtracting the 8" of bumper on both sides, that leaves us 11" to collect balls. Could people post pictures of what their design is, whether it be a rough sketch, CAD model, or actual picture? We need some ideas. Much appreciated!

Re: Funneling Balls

How do you plan on grabbing balls from the wall with that design? And how will you power it?
EDIT: And what is the rail for on the right side?

Re: Funneling Balls

It's powered by a pneumatic cylynder that rotates the arm. It's just a funnel that will help to align the balls with our induction system, so it won't actually be picking up balls, just funneling and tipping the bridge. We're picking up balls with a conveyor belt system.

Re: Funneling Balls

So it will be folded up into your robot when the game starts?

Re: Funneling Balls

Yes. It's an arm that will rotate down to flip the bridge and funnel balls if we need to.

Re: Funneling Balls

From the small length of the funneling panels, it looks like the <=12", but I'm not sure.

Re: Funneling Balls

In my experience, passive funneling devices do not work well for balls on the floor. Active grippy rollers and/or whips are a better way to go.

Re: Funneling Balls

Yeah, we're going with an active BAD* with 'whips' to pull the ball into the elevator. Very similar to Breakaway.
