Impact-resistant, autonomous robots inspired by tensegrity architecture

TL;DR - A Nature Machine Intelligence paper from Johnson et al. presents an autonomous three-bar tensegrity robot that keeps locomoting over varied terrain after extreme impacts, including a 5.7-m drop onto asphalt. It matters because tensegrity structures offer a route to robots that survive uncontrolled deployment without protective housings or repair.

• Design is a three-bar tensegrity: rigid bars held in compression by a tensioned cable network, which distributes impact loads rather than concentrating them at joints.
• Demonstrated impact resistance is quantified by a 5.7-m free fall onto asphalt, after which the robot remains functional.
• The robot is autonomous and locomotes across multiple terrain types, so the work covers control/gait generation, not just passive structural durability.
