Re: Ball posession: Roller (ball magnet) or vacuum?
I dont know what the perfect placement would be, but we have two bars that are parallel. The bottom bar is free spinning and there for the purpose of keeping the ball from being sucked under the robot by the top roller. The top roller (we have a fisher-price powering ours) is powered and has some kind of friction producing material on it. I saw many robots at the NASA/VCU with modified pool noodles, while we use friction tape... the same stuff on stairways.
The combination of the two almost pinches the ball, while the free-spinning bottom roller keeps it from picking the ball up. |
