Constant curvature forward kinematics

Definition

Constant curvature forward kinematics is a mathematical approach used to model the motion of soft robots, which are characterized by their ability to bend and stretch. This method simplifies the complex movements of these robots into predictable paths by assuming that the curvature remains constant along their length during movement. It helps in predicting the position and orientation of the robot's end effector based on its design parameters and applied control inputs.
