Machine vision is to make the machine was part of eye and brain function, the geometry can be measured automatically, the printing quality of the appearance of defects and product identification, such as the quality of the work of identification. Machine vision systems are generally used in fully automated, reliable and efficient mass production of non-contact detection in the process of identification. Common vision systems typically include: light source, lens, CCD camera, frame grabbers, image processing software, monitors, communication / input and output units, such as. Linear motion modules from the multi-axis motion system called the Cartesian coordinate robots, various sports-axis Cartesian coordinate system usually corresponds to the X axis, Y axis . Cartesian coordinate robot mainly by a number of linear motion units, drive motor, control system and the end of the composition operator. As a result of the community on the visual detection and rectangular coordinates the increasing demand for robots, it is necessary to the design of visual inspection with XY Cartesian coordinate robot. The design includes two important parts. First, the small rectangular coo
