Automatic Planning of Manufacturing Processes using Spatial Construction Plan Analysis and Extensible Heuristic Search

Ludwig Nägele, Andreas Schierl, Alwin Hoffmann, Wolfgang Reif

When automating small-batch manufacturing processes, the time spent for process planning and robot programming becomes more important. This paper proposes an automated process including construction plan analysis, process planning and execution to reduce the amount of manual work required. The process starts by analyzing the structure of the desired product and deriving required process step results, then uses heuristic search to find possible production steps and task assignments, and concludes by simulating or executing the resulting production plan. The approach is evaluated on a case study with a simulated robot automatically building different LEGO DUPLO structures starting from a 3D model defining the desired product.
