Abstract:In order to solve the problem of picking up pingpongs in table tennis filed, a kind of robot using ARM9 as the main controller was designed, and hoped that it can be applied to table tennis training fields to automatically pick up balls. This control system was selectively designed for the whole hardware structure by using S3C2440 as the main controller, OV9650 camera as visual input, and had the function of vision, image processing and mechanical control. Test shows that the robot operates reliably, which study can offer a reference to design of other similar visual robots.
