Very nice.
Your "ball magnet" looks like it works well - how does it work?

Two wheels mounted at 45 degrees from the frame. We are using 20:1 555 motors with Blue BaneBots wheels. The BaneBots wheels are slightly beveled to increase rubber contact with the balls.
The drivers had trouble controlling balls with our back turned. I'm curious to see how other teams handle this problem. We currently only have the camera for ball detection but we are considering adding a sonar. Any other ideas ?

I think Texas seems to be representing itself pretty well so far this year... Should make for some great texas shoot out matches!

With a good grip on the ball and fast enough speed, you should be able to go full reverse and hold onto the ball.

We have beveled the surface of the wheel to get more contact.
We are going to put the fisher price motors on if speed turns out to be the solution.
John,
For our kicker, we have 5 different power shots that work decently from most places on the field. The DiscoBots would love to challenge the Robowranglers to a game of robot golf !
