Abstract
Abstract A method and apparatus for processing and assembling a plurality of small parts weighing under five pounds using a robot employing a rotatable pallet for holding an array of small parts. Said rotatable pallet being held in place on the robot wrist head, which moves the pallet through a plurality of stationary work-stations located within the operating envelope of the robot, and rotates the pallet at each work-station to index the pallet and to present it to the work-station for an operation on a specific part or parts. Said robot participates in the work-station tasks by moving the rotatable pallet in the X, Y, and Z directions as needed. Movable data pins are used to indicate conditions of individual parts in nests, and of the pallet taken as a whole.
