Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation
Advanced Robotics Research, EarlyView.A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.
