Patent number: 12172303Abstract: A method for teaching and controlling a robot to perform an operation based on human demonstration with images from a camera. The method includes a demonstration phase where a camera detects a human hand grasping and moving a workpiece to define a rough trajectory of the robotic movement of the workpiece. Line features or other geometric features on the workpiece collected during the demonstration phase are used in an image-based visual servoing (IBVS) approach which refines a final placement position of the workpiece, where the IBVS control takes over the workpiece placement during the final approach by the robot. Moving object detection is used for automatically localizing both object and hand position in 2D image space, and then identifying line features on the workpiece by removing line features belonging to the hand using hand keypoint detection.Type: GrantFiled: December 6, 2021Date of Patent: December 24, 2024Assignee: FANUC CORPORATIONInventors: Kaimeng Wang, Tetsuaki Kato
