Abstract

Having a flexible robotic system layout that allows for the assembly of any structure creates a challenge in finding an optimal sequence of assembly. In some examples, the optimal sequence of assembly may provide the highest robot utilization, the shortest cycle time, the greatest assembly accuracy of the final assembly, or any combination thereof. The processing system disclosed herein may be configured to generate assembly sequences for a plurality of parts and determine an optimal assembly sequence from the generated assembly sequences by comparing the generated assembly sequences.
