Title: Optimization of fast robot motion with distance field
Inventor: LIN HSIEN-CHUNG
IPC: B25J19/06
Filed: 2021-04-01
Abstract: To provide a technique for optimizing a robot collision avoidance motion by using a distance field constraint function.SOLUTION: CAD or sensor data indicating obstacles in a robot workspace are converted to voxels, and a three-dimensional binary matrix of voxel occupancy is created. A corresponding distance map matrix is then computed, where each cell in the distance map matrix contains a distance to a nearest occupied cell. The distance map matrix is used as a constraint function in a motion planning optimization problem, where the optimization problem is convexified and then iteratively solved to yield a robot motion profile which avoids the obstacles and minimizes an objective function such as travel distance. A distance field optimization technique is quickly computed and has a computation time which is independent of the number of obstacles. The disclosed optimization technique is easy to set up, as it requires no creation of geometry primitives to approximate robot and obstacle shapes.SELECTED DRAWING: Figure 8
