Re: Effectiveness of Quadrature Encoders
 

I would agree with using a potentiometer for "elevation" tracking of an arm. Personally I think they are easier to program because utilizing the voltage (based on analog input) works just find to track its current "elevation". They also use just one analog input instead of the two digital inputs if that matters at all. And from my experience, have very little interference and usually never have to be reset. From our past robots, I would encourage the potentiometer based on its performance for us so far. The only year we had trouble with it was 2011 on our telescoping arm.... Many of you may have noticed due to the terrible sound it made when rotating at the state championship...
