What teams used wheel encoders this year?
Team 122

Quote:
How did you build it or did you buy a shaft encoder?
We bought an optical sensor; we built the encoder ourselves from aluminum and attached it to our jack shaft.

Quote:
What was its resolution?
I think we calculated ours to be +- 3 in.

Quote:
Did you use them only for autonomous or for the whole match?
Just autonomous mode.

Quote:
How did they work for you?
They were adequate for our purposes. They did give us some trouble at the beginning, though. One major obstacle we encountered was the resolution of the stamp itself -- about 25 ms if I remember correctly. You might consider using a custom circuit to get better results.

Quote:
Do you plan to use it next year?
Well, I suppose it depends on the game. But if we do then probably get a custom circuit.
