Abstract
We propose a linear approximation method of the inverser kinematics of a manipulator by using a binocular visual space. When we use a hand-eye system which has a similar structure as a human being, we can approximate the transformation from a binocular visual space to a joint space of the manipulator as a linear function. We show that the most suitable structure of a stereo camera and a manipulator for linear approximation of the inverser kinematics is similar to human being.
