ska@hercules.acpub.duke.edu writes: : Each motor has a built-in "AB quadrature output and zero index channel" : type optical encoder. These encoders output voltages in the range 0.5 to : 6 V DC via 4 leads - A, B, I, and ground. : : Now, how can I use the voltages from the encoders to compute joint positions ? Get the Monolithic Memories "PAL/PLE Device Programmable Logic Array Handbook." There are three shaft encoder designs that will explain quadrature decoding to you (if you can decipher the PALASM code). -- Jon R.
