A New Flexure Revolute Joint with Leaf springs and Its Application to Large Workspace Parallel Robot
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2012 This paper presents a flexure revolute joint with a large range of motion which can be used as a joint in a parallel robot with a large workspace. We proposed a new structure of flexure revolute joint.

Dynamic Responses of Planar Multilink Mechanism considering Mixed Clearances
Shock and Vibration, 2020 Translational and revolute joints are the main kinds of joints in planar multilink mechanisms. Translational and revolute clearance joints have great influence on dynamical responses of planar mechanisms.

Synthesis of clearance for a kinematic pair to prevent an overconstrained linkage from becoming stuck [PDF]
Mechanical Sciences, 2023 Mechanisms are prone to stuttering or even jamming due to the deformation of components, especially for overconstrained linkages for which geometric conditions must be strictly satisfied.

A recursive method for finding revolute-jointed manipulator singularities [PDF]
Proceedings 1992 IEEE International Conference on Robotics and Automation, 1995 A geometric application of screw theory is used to develop a recursive algorithm for computing all singular configurations of revolute-jointed manipulators with arbitrary link geometries and an arbitrary number of joints. The depth of the recursion is linear in the number of joints, n, while the computational burden is proportional to 2n−2. This method
