I am working on an exoskeleton project to make artificial legs to help physically challenged people walk. I have got DC geared motors at the hip to lift the leg. To control the angle of rotation, I require a sensor. And I also need a code for controlling the motion of this motor with the input from this angle sensor using arduino. Can anybody help me out with this?
I suggest you study up on current biped robots (from simple to complex) to get an idea of the mechanics and programming involved. Your exoskeleton is in effect going to be a biped bot which somebody is strapped to.
