In March 2026, researchers at the NASA MIRO IDEAS² Center advanced the development of a deployable cylindrical structural system integrating dual Hoberman rings with tensegrity-based actuation mechanisms for future space infrastructure applications.
The architecture combines the radial expansion capabilities of Hoberman mechanisms with distributed tensegrity load paths, enabling a compact stowed configuration and repeatable, mechanically predictable deployment. A centrally actuated mechanism coordinates the expansion of the structure while maintaining its overall cylindrical geometry.
A laboratory-scale prototype was developed to validate the kinematic formulation and demonstrate transitions between stowed and expanded configurations. Prototype testing demonstrated coordinated radial deployment and provided a physical platform for evaluating the interaction between the Hoberman ring mechanisms and tensegrity structural elements.
The concept provides a foundation for continued research into lightweight, scalable, and structurally efficient deployable systems for space habitats and modular infrastructure. Future development can include structural stiffness optimization, integrated sensing, and autonomous deployment strategies.
