Tang et al. 2003 : With the development of robot vision technology, robot dynamic vision is more and more concerned. Therefore dynamic vision control becomes a new subject. Compared with robot static vision that is usually called as robot vision, robot dynamic vision is on the situation when both target and environment are moving. We are setting out to design a modular reconfigurable robotics system. It is helpful for the modular reconfigurable robotics system that we are designing to meet the demands of different tasks in different working environments. Robot dynamic vision can help it decide routes and avoid obstacles for the accomplishment of the tasks by itself. This article will analyse and research robot dynamic vision system, then provide three approaches to designing vision control system. This system is being at the detecting and experimental stage. There are many things to do to put it usable.
