Here's the problem. Magnus will be mostly remote controlled as far as driving him around, making his arms move, waist rotation, neck rotation and such. However, certain features would be helpful if they were automated. Two such items are the neck and waist. If, for example, I rotate the waist via R/C to the right or left and then want to center it straight ahead again I want it to do this automatically. This would be more simple if I could use servos. But, I am having to use gear-motors due to his large size. I need some kind of feedback circuit or whatever....
I was thinking of maybe using an EZ-B and some type of slotted IR sensors placed at certain locations in the ARC of the waist or neck travel zone.
Any ideas for circuits, parts or mechanical stuff out there in forum land?
All ideas welcome!
