Application: Method for generating movement route of robot, movement route generation apparatus, robot system, and program (Patent ID: US20230398687A1)

The patent filed by Kobe Steel Ltd. describes a method for generating a movement route for a robot with multiple motion axes. The method involves placing virtual areas near the robot based on different attitudes at its operational position, assessing interference between the robot, virtual areas, and the surrounding environment, and then creating the movement route by prioritizing attitudes that do not cause interference with the virtual areas. The virtual areas can change based on the position and rotation of the robot's motion axes, with different virtual areas changing uniquely depending on their placement.

Additionally, the patent includes claims for a movement route generation apparatus, a robot system incorporating this apparatus, and a computer program to execute the process. The apparatus includes means for placing virtual areas, determining interference, and generating the movement route based on the assessment. The robot system consists of a robot with multiple motion axes and the movement route generation apparatus. The computer program is designed to carry out the steps of placing virtual areas, evaluating interference, and generating the movement route while prioritizing attitudes that avoid interference with the virtual areas. Overall, the patent focuses on optimizing the movement route of a robot by strategically placing virtual areas and evaluating potential interferences.
