Sep 7 '15 at 3:53 comment added user8373 Maybe my question wasn't clear... on some expensive servos that I've worked with you can assign the servo and absolute position or tell it to move relatively. I was imagining that with a cheap absolute position encoder, like this, you could send absolute positions, and convert relative movements to absolute positions in code. No one seems to sell these for cheap, maybe the encoders are too expensive?
Sep 4 '15 at 23:56 comment added Octopus So you want to position something absolutely, and somewhere between infinity and negative infinity?
Sep 4 '15 at 17:57 comment added user8373 I see where you are coming from, but most of the students that I work with have never done any programming or robotics before, so I want them to focus on simple concepts instead of getting into making their own feedback systems. I could pre-assemble my own motors, but then it would be hard for other educators to replicate what I've done.

Sep 3 '15 at 15:23 comment added Bending Unit 22 Then why bother using servos? Pick actuator and sensor independently and appropriate for your needs instead of being stuck with what the servo manufacturer put together. You'd want to explain what a servo is anyway, so why not circumvent the problem by building one yourself? What control algorithm should be used? What parameters? What if there's load on the motor? I think knowing how to control a motor is essential for robotics and a valuable thing to learn for a beginner.
