Built by Robots: Human-Machine Collaboration in Construction

From June 30 to July 11, the two researchers Dr. Konrad Graser & Dr. Alex Walzer from the Zurich University of Applied Sciences (ZHAW) came to Osaka, to explore deeper the question of How can robotics transform the way we build? Through events and meetings, they dived deeper into the transdisciplinary perspective of construction building and the relationship between human and robotics. 

Rethinking the Future of Construction

On July 8, Swissnex in Japan hosted “Built by Robot?”, an exciting afternoon dedicated to showcasing Switzerland’s latest advances in robotic construction, supported by Presence Switzerland and held at the Swiss Pavilion.
The event kicked off strong, featuring PechaKucha-style presentations from ETH Zürich’s Tor Alva and pioneering startups, including MESH, SAEKI, LAYERED, and Impact Build. From 3D-printed clay walls to automated large-scale fabrication, attendees gained insight into how Swiss research and industry are transforming the future of the built environment.

A lively panel discussion, moderated by Prof. Ming Shan NG (Charmaine) (Kyoto Institute of Technology), brought together Dr. Konrad Graser and Dr. Alex Walzer (ZHAW Zurich University of Applied Sciences) alongside Prof. Benjamin Dillenburger (ETH Zürich). The panel offered diverse viewpoints on digital building technologies, exploring both technical innovations and the sociotechnical dynamics involved.

Transdisciplinary means going beyond disciplines, bridging education, industry, and more, where knowledge is co-created through equal exchange, with half of it rooted in practice.

In their presentation, Dr. Graser and Dr. Walzer focused on embedding robotics into construction processes, emphasizing the crucial interaction between humans and machines. They approached these challenges through detailed case studies, analyzing construction projects including not only technical expertise on the delivery and methodologically sound assessment of construction prototypes. Their work is all about bridging the gap between digital design and physical reality, ensuring new construction methods are not only visionary but also feasible. Having studied pioneering approaches across Switzerland and Europe, they are now expanding their research into Japan, engaging with leading Japanese construction companies and research institutes. 

Including a management perspective to understand what drives success and helps advance the technology, their work arose from recognizing a disconnect between academic research and industry needs. By placing practical requirements at the core, they investigate how innovation truly occurs, exploring organizational models that support transforming inventions into market-ready solutions. This sociotechnical approach seeks to strike the right balance between human skills and robotic capabilities.

Through micro-level analysis of interactions—between humans, and between humans and machines—they aim to bridge the gap between research design and real-world implementation. This innovative methodology shows great promise for the future of construction.

The afternoon concluded with an interactive survey and networking apéro, alongside a guided tour of the Swiss Pavilion, where visitors could observe how innovation and sustainability are seamlessly integrated into its architecture.

Exploring Human-Robot Innovation Across Japan

Between June 30 and July 11, 2025, Dr. Konrad Graser and Dr. Alexander Walzer through the ZHAW-Swissnex Staff Mobility Program embarked on an intensive meeting tour across Tokyo and Osaka. In addition to co-organizing the event “Built by Robot?” at the Swiss Pavilion, the researchers took part in a packed schedule of site visits and institutional meetings focused on architecture, robotics, technology, and design. Their engagements, notably with Japanese corporations, and architectural firms offered rich insights into the evolving interface between robotics and construction in Japan. Their program also included visits to several national pavilions at Expo 2025, further enriching their exploration of innovation across contexts.
