Design and Analysis of an Intelligent Toilet Wheelchair Based on Planar 2DOF Parallel Mechanism with Coupling Branch Chains [PDF]
Sensors, 2021 Due to the fixed size of the structure or the possibility of only simple manual adjustment, the traditional toilet wheelchair cannot easily be adapted to the size of the user or the toilet. In this paper, a planar two-degree-of-freedom parallel mechanism

Structure of Parallel Mechanism Combined with Waterbomb-Base-Inspired Origami
Engineering Proceedings, 2023 Structure from the geometry and analysis of the three-spherical kinematic chain-base parallel mechanism have been studied. The parallel mechanism evolved from an origami fold as chain legs with three spherical kinematic chains becoming rigid bodies.

Positioning Accuracy Analysis of the Parallel Mechanism Near Singular Positions
International Journal of Applied Mechanics and Engineering, 2015 This paper presents a method of numerical modelling of parallel mechanisms with clearances in their kinematic pairs taken into account. The pairs with clearances are modelled as shape connections based on constraints in the form of contact interactions ...
