Statically Stable Assembly Sequence Generation for Many Identical Blocks

Abstract

This work develops optimal assembly sequences for modular building blocks. The underlying concept is that an automated device could take a virtual shape such as a CAD file, and decide how to physically build the shape using simple, identical building blocks. The primary focus of this work is the development of methods for generating assembly sequences in a time-feasible manner that ensure static stability at each step of the assembly. This is accomplished by a multi-hierarchical rule-based approach, consisting of a set of low-level, mid-level and high-level assembly rules. Both high-level and mid-level assembly rules are primarily based on static considerations. The best performing rules are presented and their behavior is analyzed.
