Kinematic Modeling

Definition

Kinematic modeling is the mathematical representation of the motion of robotic systems without considering the forces that cause this motion. It focuses on the geometric relationships between different parts of a robot and how these parts move in relation to one another, allowing for precise control and analysis of movement in applications such as automation and medical procedures.
