Re: Designing with sensors
We used PVC tubing for a U-shaped pickup mechanism in 2014, chosen for its flexibility, so that the arms could spread around the 2' diameter game pieces. The problem was that because it flexed, the encoder magnet at one end of the shaft did not stay in perfect alignment with the encoder.
We solved it by using a gates belt off the pickup shaft to drive a steel shaft for the encoder.
