Re: Modifications to FIRST Gray Wheels for Better Consistency
Team 3322 uses 2 2010 8" Rubber treaded FIRST wheels with 1.5" of compression. We tested compression up to 2.5", which did not work well at all. Our shooter is in the style of an "S," so we have a larger period of contact between the ball and the shooter wheel. We also feed balls with a 4" foam wheel coupled to a window motor. The slow speed of the window motor gives time for the RPM of the shooter wheel to reapproach the assigned speed (with PID).
Mechanically, our feed wheel is attached to a spike. Within our code, the feed wheel will not run unless the speed of the shooter is at the set value.
