Abstract

A method for automatically correcting displacement errors in robotic systems for part locations accessed by robot arms on assembly trays is disclosed. Part locations on trays are currently set in a robotic system using either a teaching or a framing method. The teaching method involves showing a robotic system where a part is located by moving a robot arm manually to each individual part location and subsequently saving a value representing that location in memory of the robotic system. Time incurred teaching is a major drawback of the teaching method when there are many parts on the assembly trays.
