Redefining walking: A bio-inspired kinetic architecture

The concept of The Walking City demonstrated the potential of what has been termed 'walking architecture' to transcend the constraints of traditional static dwelling and organized transportation systems. But the interdisciplinary complexity and the specific demands of walking architecture have posed considerable challenges to its practical implementation. From an architectural engineering perspective, integrating mobility into built structures requires reconciling structural stability with dynamic movement—two traditionally opposing principles in design management. While conventional wheeled systems limit design innovation, robotic leg mechanisms are incompatible with architectural structural demands. Thus, no kinetic architecture model has yet been developed that fully actualizes the vision of walking architecture. This study aims to close this gap by assembling a multidisciplinary team of architects, civil engineers, and roboticists to develop a viable walking model for architectural structures. Drawing from bio-inspired design and non-legged locomotion principles, the project developed a blue whale vertebrae-inspired modular system to optimize stability and spatial efficiency. This framework was adapted with Jansen's caterpillar mechanism, enabling kinetic architecture to navigate uneven terrain. The conceptual design's robustness was first validated through simulation and static analysis, followed by a 1:10 scale proof-of-concept prototype to test technical feasibility of actuation and control systems. In the final experiment, the prototype walked 36 cm in 30 s (0.043 km/h) without structural failure, validating the design approach. By bridging architectural design principles with structural dynamics and robotic actuation, this study contributes to the emerging discourse on kinetic architecture, providing a new framework for integrating movement into built environments.
