The migrating walls.

This paper presents a comparison of different workflows for mobile robotic fabrication using modular building blocks. Different localization, locomotion, and interlocking building systems strategies are tested and compared. The work is influenced by related research into ecosystems of building parts, design software, and builder robots to digitize the construction work. For localization, it compares LIDARs, reacTIVision, and ArUco markers. As a mobile platform, a MIR100 robot platform, a 3.3 m linear axis, and a manual trolly are used. Interlocking components such as wood slates, custom-made bricks, and interlocking wood building blocks are used. The research is in the field of collective robotic construction (CRC) using bespoke robots designed in tandem with specific discrete building blocks. [ABSTRACT FROM AUTHOR]
