【正文】 n robot applications has been opened with the development of “intelligent robots”. An intelligent robot is bascally one that must be capable of sensing its surrounding and possess intelligence enough to respond to a changing environment in much the same way as we do. Such ability requires the direct application of sensory perception and artificial intelligence. Much of reseach in robotics has been and is still concerned with how to equip robots with visual sensorseyes and tactile sensorsthe”fingers”. Artificial intelligence will enable the robot to changes in its task and in its environment, and to reason and make decisions in reactiong to those changes. Visional Sensory Much effort has been made to simulate similar human sensory abilities for inelligent robots. Among them ,vision is the most important sense as it is estimated that up to 80% of sensory information is received by vision. Vision can be bestowed on robotic systems by using imaging sensors in various ways. For improving accuracy of performance, it can help precisely adjust the robot hand by means of optical feedback control using visual sensors. Determining the location, orientation, and recognition of the parts to be picked up is another important application. Among the vision system, one of the key ponents is imagery sensor. The imagery sensor of a robot system is defined as an electrooptical device that converts an optical image to a video signal. The image sensor is usually either a TVcamera or a solid state sensory device, for exanple, changecouple devices(CCD). The latter device offers greater sensitivity, long endurance and lightweight, and is thus wele when pared with the TVcamera. The camera system contains not only the camera detector but also, and very importantly, alens system. The lens determines the field of view, the depth of focous, ans other optical factors that directly affect the quality of the image detected by the camera. Either TVcamera or CCDs produce an image by generating an analogue value on every pixel, proportional to its light intensity. To enable a digital puter to work with this signal, an analonguetodigital(A/D) converter is needed to transfer analogue into digital data, then stored in random
