Buildings have substantial socioeconomic and environmental impact on society, while construction itself remains a dangerous undertaking. Partially addressing this, the building industry is slowly adopting robotic manufacturing methods in order to increase far lagging productivity, yet there remains a serious need to re-think the way buildings are designed and constructed to address both practical needs and creative opportunities in order to build a brighter, more equitable future. While autonomous systems in robotics research is focused on a particular set of robot control orientated application scenarios, engaging with varying degrees of autonomy in architectural design, fabrication and construction offers an alternative approach to a broad range of architectural and construction challenges. Use of autonomous programming within multi-objective design-engineering, or to provide adaptation and situated awareness within fabrication or construction, offers increased efficiencies, capabilities, and creative opportunities to re-think the built environment. This lecture presents a number of research projects that leverage multi-agent systems, behavior-based control, and collective robotic construction for the generative design and/or construction of buildings.
