Ball Magnet

We tried our idea for a "ball magnet" basically a way to POSSESS the ball.

Re: Ball Magnet

How does the robot do that??? According to the Youtube post, it has something to do with the wood, but it sounds like there is a vacum behind it.

Re: Ball Magnet

I think its that the conveyor belt is running, which pushes the ball into the block of wood.

It appears to me that something that is not spinning when they do the close up starts spinning when they pull the camera away. :D

Nice Work!

Re: Ball Magnet

That's quite impressive. I'm assuming you don't break the 3" rule from the front of the roller to the piece of wood. I ask because it looks pretty deep in the video (not that I can tell much from that angle).

Re: Ball Magnet

This is set up to demonstrate the principle, and use the old robot with no modifications other than screwing in a piece of wood. When implementing this on the new robot, we will take all the rules into account.

Re: Ball Magnet

I guess that Robocup robots come standard with "Ball Magnets" too...

Re: Ball Magnet

This is close to something we are considering implementing.

Your robot still looks intimidating.

Re: Ball Magnet

how exactly does this not break the rules, you are controling the direction and position of the bal???

Re: Ball Magnet

You are POSSESSING the ball, which you are allowed to do. <G43>.

This is how.

Quote:

POSSESSION: Controlling the position and movement of a BALL. A BALL shall be considered in POSSESSION if, as the ROBOT moves or changes orientation (e.g. backs up or spins in place), the BALL remains in approximately the same position relative to the ROBOT.

Quote:

<G43> ROBOT BALL POSSESSION - ROBOTS may POSSESS only one BALL at a time. Violation: PENALTY.

Please read your rules.

Re: Ball Magnet

It's ridiculous how many people I have heard point out the fact that some new design POSESSES the ball. Thank you for pointing out something that is legal people! lol :rolleyes:
