Publication number: 20180281175Abstract: Example systems and methods are disclosed for determining tool offset data for a tool attached to a robot at an attachment point. The method may include controlling the robot to contact a reference object with the tool. The reference object may be a rigid object with a known location. A force feedback sensor of the robot may indicate when the tool has contacted the reference object. Once contact is made, data indicating robot position during tool contact may be received. Additionally, the robot may temporarily stop movement of the tool to prevent damage to the tool or the reference object. Next, tool offset data may be determined based on the position of the reference object relative to the robot and the received robot position data. The tool offset data may describe the distance between at least one point on the tool and the attachment point.Type: ApplicationFiled: June 7, 2018Publication date: October 4, 2018Inventor: Benjamin M. Davis
