The PROBLEM:    During meet 1, we found that the shooter accuracy was very inconsistent. This made it hard to score rings in both Autonomous and Driver-Controlled portions of the meet. During the Driver-Controlled portion, the team could compensate somewhat if they saw they were shooting too high or too low, but we usually wasted a couple of rings determining how far off we were.  The DIAGNOSIS:    Shooter accuracy appears to have been affected by at least two different factors.   1) The mechanism for feeding rings into the shooter wheel did did not consistently deliver the rings the same way every time. Sometimes rings would be tipped at a slight angle when hitting the wheel or hit the wheel at a different speed.   2) The speed that the motor itself is spinning seemed highly dependent on the battery power. During one match, we used a battery that seemed overcharged and had a higher voltage than the previous ma...
