  • Patent number: 11787056
    Abstract: 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.

  • Publication number: 20230158671
    Abstract: A system for the intelligent obstacle avoidance of multi-axis robot arm includes a multi-axis robot arm and a host device. The multi-axis robot arm includes a plurality of knuckles and a plurality of connecting arms. The plurality of the connecting arms are alternately connected with the plurality of the knuckles. The host device is electrically connected with the multi-axis robot arm. The host device includes a database device, an operation control module and a signal transmission module. The database device, the operation control module and the signal transmission module are electrically connected. The signal transmission module transmits a control signal to the multi-axis robot arm for performing an optimum obstacle avoidance posture.
