Curvature

Definition

Curvature refers to the measure of how much a curve deviates from being a straight line, quantifying the bending of a structure. In the context of soft robotics, curvature is crucial as it directly affects the movement and flexibility of soft robots, influencing their ability to navigate complex environments and perform intricate tasks.
