Locking devices are widely used in robotics, for instance to lock springs, joints or to reconfigure robots. This review paper classifies the locking devices currently described in literature and preforms a comparative study. Designers can, as such, better determine which locking device best matches the needs of their application. The locking devices are divided into three main categories based on different locking principles: mechanical locking, friction-based locking and singularity locking. Different lockers in each category can be passive lockers or active lockers. Based on an elaborate literature study, the paper summarizes the findings by comparing different locking devices, based on a set of properties of a theoretical ideal locking device.

To extend the functionality of the overrunning clutch. A new overrunning clutch with the characteristic of reverse torque transfer direction at high speed is proposed in this paper. This clutch consists of a traditional one‐way overrunning clutch and a reverse torque transfer direction subsystem. It has three work scenarios according to the angular velocity relationship between the master shaft and the slave part, which are positive torque transfer direction, overrunning, and reverse torque transfer direction. The principle and schematic structure of this clutch are detailed, relationships among the rollers, springs, and hammers are discussed, and threshold angular velocity of reverse torque transfer direction is achieved. The dynamic model of the reverse torque transfer direction part of this concept is established with Simulink software. A series of simulation scenarios that the slave shaft's rotational speed changed at different spring stiffness is conducted. The results show that the threshold value of the reverse torque transfer direction is increasing with the decrease of the spring stiffness. At last, a prototype system is made to roughly validate the feasibility of this concept.
