To all the teams out there please just state your team number, what drive system your team uses this year, and what sensor it is and where you purchased it. Just a quick survey am taking. Thank You.

We use the West Coast Drive.
For this year and the last several years we use optical encoders. This year we used the BaneBot encoders (on the AM gearboxes). In the past we’ve used the Grayhill encoders, or other encoders (I think we’ve used different encoders each of the last 4 years – they all seem to work about the same). We also use a gyro.
We also use lots of other sensors on our robot, but that’s all for the drive.
Team: 703
Drive system: 14 Wheel, Tank Style Drive (custom wheels), with custom 2 speed Pnumatic Shifter.
Sensors: 2 Optical Encoders with custom made Digital-to-Analog converters (to simplify programming and wiring; don’t ask me how it works, I have no idea).
