This thesis mainly investigates the construction and control of a robot arm, powered by several AI-1001 servomotors, in order to mimic a human arm's motion. The robot arm is controlled via Borland C++ Builder codes, which are transmitted by RS232 to each AI motor. In order for the robot arm to have the vision capability, like a human pitcher, a CCD webcam is added to capture target image. After image processing and analysis, controller can compute and then issue the motion commands to the robot arm. The vision system helps promote system's intelligence and improves pitching precision. Furthermore, placing the robot arm onto an autonomous vehicle increases its mobility. Two experiments are performed to demonstrate its ability. The static target is 9 prearranged rectangles. The dynamic target is an air-floating ball, which is kept in midair using a blower. The blower is fixed on a remote-controlled car, consisting of AT89S51 and RF, and can control the ball trajectory.
