A robot joint is a mechanical articulation connecting two adjacent robot links that permits one or more degrees of relative motion—translational (prismatic) or rotational (revolute). Robot joints are the fundamental kinematic elements that determine a manipulator’s workspace and degrees of freedom; their dynamic properties, including inertia, backlash, and compliance, critically influence both control precision and safe interaction with the environment.
