I have been looking into various control systems for a robot arm. One of the methods I have been looking into is color tracking. I thought this could be done by using a glove with a color on one finger and two cameras to get 3D. One of the cameras could capture X and Y axis, and the second camera could capture Z axis. I know this could be done with one camera, by decrease and increasing size of the colored area, but I would like to keep it simple. Has anyone else done something similar, or any better ideas for robot arm control systems?
PS the area the arm need to operate is around 70 X 70 X 70 cm.
