Re: Mechanism to Possess Soccer Balls
 

Slow is definitely better, we tried last-years robot with a piece of plywood at three inches from the roller, and it kept it in perfectly. We then tried our shooter from 2006 just as a test, and well the ball has a nice 1/8" deep grind mark in it from the shooter :p

Soccer balls do NOT compress like Orbit balls! We're looking at designing a pivoting support for the roller to keep relatively constant pressure on the ball.

vacuum may work too good

our roller works pretty well, and right now we're testing different types of roller material, to test the best friction force. How do you think i could make the roller that had a spring on the two sides so the roller would compress up and capture the ball better and when the ball wasn't underneath it, it would release the tension in the spring and it would go back down to its original position?
