Abstract
A method and system for analyzing data describing touchups to a robot's tool center point position. A robot operator performs the touchups to a robot's tool center point position when the operator notices inaccuracies in the location of operations performed by the robot—such as a spot weld in a wrong location on a workpiece—where the inaccuracies may be caused by mechanical wear in robot joints. Each operator-defined touchup changes the position and optionally orientation of a particular point in the robot's motion program. The disclosed method provides a graphical display of the history of position touchups for the robot, and analyzes the touchup data against certain criteria for the distance, direction and frequency of the touchups. When the analysis determines that any individual or combination of criteria are met, an alert is provided which indicates a possible mechanical wear issue exists with the robot and needs attention.
