OPENTECHNICAL PUBLICATION OT-2026-000002452 Robotic arm path planning method based on directionally extended rrt algorithm Published: 2026-09-15T19:13:10.634004Z Permanent URL: https://opentechnical.org/p/OT-2026-000002452 Categories: Robotics & Automation > Robot Architectures ------------------------------------------------------------------------ ABSTRACT A robotic arm path planning method based on a Direction Extended Rapidly-exploring Random Tree (RRT) algorithm includes: determining a workspace of a robotic arm; determining a starting node and a target node based on the workspace, and performing modeling using an initialized random tree to obtain an obstacle space; generating a random node in the obstacle space, and setting a bias probability; determining whether a current random node collides with an obstacle; if yes, obtaining a new random node, until a currently generated random node does not collide with an obstacle; if not, determining whether the current random node is the target node; if the current random node is not the target node, continuing to generate new random nodes; if the current random node is the target node, obtaining an initial path; and optimizing the initial path to obtain a final path. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002452 Published 2026-09-15T19:13:10.634004Z https://opentechnical.org/p/OT-2026-000002452
