Patent number: 11787056Abstract: An obstacle avoidance method for a robot arm is provided, including a modeling step, a collecting and evaluating coordinates step, an obtaining control parameter step, an establishing an occupation function step, and a finding an obstacle avoiding posture step. The present invention pre-stores the data obtained in performing the modeling step, the step of collecting and evaluating coordinates, the step of obtaining control parameter, and the step of establishing the occupation function into a database, thereby allowing the robot arm to quickly evaluate whether a collision behavior will occur in subsequent execution of a task. If a collision will occur, the robot arm executes the step of the finding the obstacle avoiding posture to dodge obstacles. The invention uses a non-contact approach for anti-collision design, which can improve the shortcomings faced by the existing contact type anti-collision design.Type: GrantFiled: September 14, 2021Date of Patent: October 17, 2023Assignee: Cheng Uei Precision Industry Co., Ltd.Inventors: Po Ting Lin, Chao Yi Lin, Shih Wei Lin, Kun Cheng Li, Chang Yun Yang, Pei Fen Wu, Shun Chien Lan
