The purpose of this paper is to upgrade the traditional robotic arm system, which can only follow the instruction to work, cannot determine by system itself to complete the tasks. Therefore, we integrate image recognition into system in order to make the system recognize the target object then catch it and place it into box; in addition, the system can automatically troubleshoot the malfunction. As for the communication of the system, the image recognition definitely take time to process, we choose therefore the EtherCAT protocol to reach the goal of operating smoothly and rapidly. This paper presents the basic principles and background, and explain the details of the system architecture and hardware configuration. In the experiment results, we depict each part of the actual system and show the achievement of the image recognition robotic arm system.
