Quasi optimal sagittal gait of a biped robot with a new structure of knee joint [PDF]

open access: yes, 2013
The design of humanoid robots has been a tricky challenge for several years. Due to the kinematic complexity of human joints, their movements are notoriously difficult to be reproduced by a mechanism. The human knees allow movements including rolling and

Proposed Shaft Coupling Based on RPRRR Mechanism: Positional Analysis and Consequences

open access: yesAxioms, 2023
This study proposes a solution for the transmission of rotation motion between two shafts with crossed directions. For constructive simplicity, the solutions including the planar pair were preferred and, from the two variants, namely structurally ...

Normalized-constrained approach for joint clearance design of deployable overconstrained Myard 5R mechanism

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This paper proposes a normalized-constrained approach for the joint clearance design of deployable overconstrained Myard 5R mechanism. Firstly, the overconstrained mobility characteristic of Myard 5R mechanism is analyzed, we show that the dimensional ...

Kinematic Analysis of a Serial-Parallel Hybrid Mechanism and its Application to a Wheel-Legged Robot

open access: yesIEEE 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 ...

Minimizing Misalignment and Frame Protrusion of Shoulder Exoskeleton via Optimization for Reducing Interaction Force and Minimizing Volume

open access: yesMachines, 2022
Although industrial shoulder exoskeletons have undergone rapid advancement, their acceptance by industrial workers is limited owing to the misalignment and interference between the exoskeletal frame and the wearer’s body and bulkiness of the frames ...

A New Flexure Revolute Joint with Leaf springs and Its Application to Large Workspace Parallel Robot

open access: yesJournal 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.

Experimental investigations of the dynamic responses of a multi-link mechanism with revolute clearance joints

open access: yesAdvances in Mechanical Engineering, 2021
Joint clearance is unavoidable in the revolute joint of multi-link mechanism. Excessive value of joint clearance generally leads to the noise, vibration, and fatigue failure.
