Visual servoing utilizing zoom mechanism [PDF]
Proceedings of 1995 IEEE International Conference on Robotics and Automation, 1998 A camera, which is used as an artificial vision in visual servoing control, often has a zoom mechanism. A zoom mechanism cannot realize fast motion while an arm mechanism can, and it has only one degree of freedom. On the other hand the arm mechanism cannot cover wide range of change of images while the zoom mechanism can.
