Re: Accelerometer vs Gear Tooth Sensors
This is my rookie year, and I already got delegated to figuring out how to use the camera, gear counters, and the accelo-thingie.

Counting the gear teeth is probably the only logical thing to do with the counters (duh), unless you felt like gearing a manipulator that couldn't be brute-forced safely.

As for the accel., I guess the best use for it is to detect side-to-side movement during the auto period. Just because your bot moved to the side does not mean that the gears turned, especially with this year's gearboxes. So, the accel. may (or may not) cover this angle.

Once I find the code, I'm going to try to combine the two to create a point-to-point system. The only trouble is that the accel. seems like it would be a bit twitchy, and figuring out how far it was bumped using g-forces seems like it would be hard. Also, figuring out how to code the auto period so that any recovery manuevers aren't counted as going to the given point is going to take a while.

Oh well. I might post some code up later, since the meeting is tonight.
