Forward kinematics

Definition

Forward kinematics is the process of calculating the position and orientation of the end effector of a robot based on given joint parameters. This involves using mathematical models to determine how each joint movement affects the overall pose of the robotic system. In soft robotics, understanding forward kinematics is crucial for controlling the movements of soft actuators, allowing for precise manipulation and interaction with the environment.
