Latest Patents

Changhao Wang holds a patent for a "Collision avoidance motion planning method for industrial robot." This patent describes a technique that utilizes a worst state search and optimization to prevent collisions during robotic operations. The method begins with defining obstacles, start and goal points, and an initial set of waypoints. By employing an inter-point interpolation method, a continuous trajectory is created. The worst state search identifies locations between waypoints that pose the highest risk of collision, allowing for the establishment of collision avoidance constraints. The optimization process then refines the waypoint locations to eliminate all potential collisions while meeting minimum distance criteria from obstacles.
