The author deals with underactuated robots, i.e. with robotic systems which possess more joints than actuators. Using kinematics and dynamics-based formulations of manipulator dexterity, the author characterizes passive-joint singularities, thus describing new joint-limit singularities. As an example the author obtains space diagrams for the unlocked dexterity of a planar 3R manipulator whose third joint is passive and free-swinging or locked.
