I've built a rudimentary motion control system with Mindstorms, but
as the motors are not really steppers, I found I had some precision
issues. Pulsing and timing never really got close enough for a
repeatable move. You can use rotation sensors as well, and since your
doing stop motion, I'm assuming speed is not of the essence. You may be
able to get close enough to what you need to do by moving very slowly
and feeding back a lot of information. If you're not really a purist and
don't ming adding some non Lego stepper motors, then you'll have an
easier time.

| Hi all, I'm a lurker/newbie. I'm wanting to build a controlled platform that can move and rotate (sort of like a turtle using LOGO). I'd like this platform to carry my E-10 camera (weighs 37 oz./1048 grams). Can anything using the RCX/mindstorms (...) (21 years ago, 12-Nov-03, to lugnet.robotics)
