Abstract

This article describes a complaint robot gripper mechanism which provides for accurate pick-up of a part as well as for accurate placement of that part at assembly. Totes deliver work in process (WIP) to various workstations via some type of material handling system, such as a conveyor. The WIP is carried inside inserts within a tote. Because of normal tolerances associated with the insert, parts are not always positioned within the insert with a high degree of accuracy. Also, parts are shifting within their insert pockets during normal conveyor transfer. This complicates accurate part placement from the insert to the part destination, onto a pallet, or directly into a workstation.
