The NERDS made a ball magnet to possess the balls in the FIRST Robotics Competition Breakaway game. It's just a piece of wood, but it seems to hold the ball just fine. We will work on adjusting the location, speed, and width of the roller to optimize it.

  • the rules state that the ball has to be released when you back up, no?

  • Not that we know of. It says that if the ball moves with the robot when the robot drives backwards, then it is considered possession. But possessing one ball is legal, possessing two is not legal. So we are making ours so it can only possess one ball at a time (narrowing the ball magnet)

  • What is the roller material? Are you within the 3 inch rule with that configuration?

  • The roller is ABS pipe with spray rubber on it. The front of the roller is just over 3" forward of the wood that blocks the ball, so it would be able to fit in the 3 inch rule if the roller were a bit smaller diameter, and mounted at the outer edge of the robot, just inside the frame.

    You have to use your imagination to see how it would work on a 2010 robot, because the concept prototype was done on a 2009 robot which is designed to play a different game.

    Does that help, Frank? :)

  • possesion isn't banned- carrying is banned

    possesion is when the robot moves the ball stays in the same position relative to the robot. thats fine

    carrying is when the ball is in possesion but it isn't touching the ground

    thats not legal

  • Ball can go three inches into the frame perimeter. Kicker can extend to bumper perimeter for up to two seconds, then has to stay retracted for two seconds. But this robot in the video is from 2009 so don't worry that it does not meet the rules!

  • LOL! Nice usage of your '09 robot!

  • guys if thats for the 2010 comp thats illeagle you can not carry balls

    team 3207 is going to atlanta!!!

  • Good luck teams for tommorow

  • gotta love loopholes, really nice design. haha

  • @sswan1 its all right if its only one ball, and as long as it stays in contact with the ground, it is legal

  • "optimize" possibly the most overused word in the engineering world.
