Dexterity, in robotics, is the ability of a manipulator to achieve a broad range of end-effector orientations and positions within its workspace, particularly in the vicinity of a given point, without encountering kinematic singularities. It is quantified by measures such as the Jacobian condition number, manipulability ellipsoid volume, or isotropy index. High dexterity enables a robot arm to approach objects from many angles, reconfigure during a task, and avoid joint limits — properties critical for assembly, surgery, and unstructured manipulation tasks.
