Revolute joints with clearance in multibody systems [PDF]
Computers & Structures, 2004 A computational methodology for dynamic analysis of multibody mechanical systems with joint clearance is presented in this work. Clearances always exist in real joints in order to ensure the correct relative motion between the connected bodies being the gap associated to them a result of machining tolerance, wear, and local deformations.

Kinematic Analysis of a Serial-Parallel Hybrid Mechanism and its Application to a Wheel-Legged Robot
IEEE Access, 2020 A three-DOF (degree-of-freedom) serial-parallel hybrid mechanism is proposed that consists of a 2-UPS+U component (UPS: universal-/prismatic-/spherical-joint chain and U: universal joint) and an R+RPS component (R: revolute joint and RPS: revolute ...
