Tendon Locking for Antagonistic Configuration- and Stiffness-Control in Soft Robots

ICRA 2025

Some applications, such as surgical interventions, require that potential soft robots have the capability to alter their shape and enhance their force output on demand. This paper presents an antagonistic stiffening mechanism combining pneumatic actuation with tendon locking to achieve configuration
