This invention discloses a motion planning method for a seven-DOF robotic arm system, comprising a six-DOF robotic arm and a guide rail. The method first obtains key configuration parameters, dividing the system's revolution angle around a fixed point into n regions and establishing a one-to-one mapping with n predetermined positions on the guide rail. These parameters include the boundary angles of each region, the corresponding guide rail positions, and floating thresholds set for both to suppress fluctuations in region boundary identification caused by floating-point precision. Subsequently, the current revolution angle and guide rail position are identified to determine the target revolution angle. Based on the region numbering relationship between the current and target angles and the current guide rail position, a motion path is adaptively generated. This path is achieved through asynchronous coordination of the robotic arm joint motion and the guide rail linear motion, maintaining a constant end-effector posture throughout the process. This invention avoids real-time kinematics solving through discretization and parameter mapping, improving planning stability, system adaptability, and motion efficiency.
