Compliant control

Definition

Compliant control refers to a strategy in robotics that allows a system to adjust its behavior based on interaction forces, enabling it to adapt to varying environments and tasks. This concept is especially important for soft robotics, where structures are designed to be flexible and can change shape or stiffness in response to external stimuli. Compliant control enhances the ability of soft robots to manipulate objects gently and safely while maintaining stability and precision.
