Hybrid Intelligence Design & Architectural Robotic Systems
The Hi-DARS lab (Hybrid Intelligence Design and Architectural Robotic Systems) is a design research hub dedicated to advancing the integration of Hybrid Intelligence, Architectural Robotics, and innovative Design Systems within architecture, the construction industry, and built environment technologies. By developing integrated approaches that merge human and machine intelligence, the Hi-DARS lab systematically incorporates hybrid intelligence into design and building processes while also exploring the broader socio-cultural impacts of automation, machine intelligence, and robotics. The lab emphasizes the crucial role of design-build processes as influencers in social and environmental spheres, linking practical material applications with the broader, interconnected dimensions of ecological and societal frameworks. Located at Texas Tech University’s Huckabee College of Architecture, Hi-DARS fosters national and international collaborations, aiming to create a knowledge exchange platform that enhances design and construction practices worldwide through emerging technologies and advocates for solutions that are circular, resilient, and adaptable to various geographical contexts.
Hybrid of Phygital Design-Build MEDIUMS
Mixed Reality Co-Design and Building: Employing Mixed Reality technology, we're revolutionizing construction processes for enhanced efficiency. This advanced approach optimizes the use of materials like concrete and wood, collaborating closely with local architectural design firms and building contractors.
Hybrid Human-Robot Collaboration METHODS
The future of construction is shaped by the strategic collaboration between humans and robots on construction sites. This entails creatively integrating technology to establish novel roles for humans. The aim is to enhance efficiency while mitigating risks, reducing costs, and significantly improving productivity. This innovative approach not only transforms the construction landscape but also paves the way for new job markets and architectural practices.
Hybrid of Circular MATTERS
Our focus is recycling common construction materials like wood, brick, and concrete. We use advanced techniques, such as 3D printing, to transform waste materials into alternative resources. By doing this, we aim to reduce the environmental impact and lower the carbon footprint of building processes. We aim to work closely with local, national, and international industry partners and suppliers to make this happen.

Erik Zanetti & Daniel Fischer are invited as guest speakers in Hi-DARS lab’s TALK SERIES
This study explores the integration of Augmented Reality (AR)-enabled production/assembly processes and digital fabrication techniques with reclaimed materials. The case studies introduce augmented production methods in the context of recent advancements in circular construction and regenerative design. By examining the capacities of these methods, this research addresses the expanded construction possibilities afforded by non-standard and reclaimed materials. Building on the integration of AR-enabled production/assembly processes and digital fabrication, including robotic milling and 3D printing with reclaimed materials, this paper explores practical applications through three case studies. Each project develops an augmented fabrication workflow tailored to reclaimed materials, ranging from robotically modified reused wooden elements to wooden bricks cut with an AR-equipped bevel sliding miter saw, and reclaimed paper tubes connected by 3D-printed joints in recycled wooden filament. The paper discusses the methodologies applied and the specifics of the one-to-one scale prototypes presented.
