Development of Two-Way Self-Adaptive Gripper Using Differential Gear
Actuators, 2022 In this paper, a two-way self-adaptive gripper that has adaptability to external disturbance loads during linear opening/closing pinch actions and adaptability to encompass a variety of shapes during grasping using a single actuator is proposed, unlike ...

A Rigid-Foldable Kirigami-Inspired Metamorphic Mechanism With Programmable Motion Modes and Self-Locking. [PDF]
Adv Sci (Weinh)Geometric constraint reconfiguration enables a rigid–foldable kirigami‐inspired mechanism to switch between twisting, directional translation, and self‐locking states. By encoding multifunctionality directly into its architecture, the mechanism achieves multimodal motion and passive locking without reassembly, providing a compact platform for adaptive ...

Virtual and Physical Prototyping of Reconfigurable Parallel Mechanisms with Single Actuation
Applied Sciences, 2021 The paper presents novel models of reconfigurable parallel mechanisms (RPMs) with a single active degree-of-freedom (1-DOF). The mechanisms contain three to six identical kinematic chains, which provide three (for the tripod) to zero (for the hexapod ...

A Treatise on the Theory of Screws [PDF]
Nature, 1901 SIR ROBERT BALL'S “Theory of Screws” is one of the most notable modern extensions of theoretical dynamics. It is based on Poinsot's discovery that every set of forces, regarded as acting on a rigid body, is reducible to a force along one definite line and a couple round the line; combined with Chasles's discovery that every instantaneous motion of a ...

A New Design of the Tooth Profile for Single Screw Compressors [PDF]
, 2012 The wear of star wheel teeth is an importance issue in the single screw compressor. In order to enhance the wearresistance of star wheel teeth, some new profiles of the meshing pair were proposed to replace the currently used straight line envelope ...

Solution of an inverse kinematics problem using dual quaternions
International Journal of Applied Mathematics and Computer Science, 2020 The paper proposes a solution to an inverse kinematics problem based on dual quaternions algebra. The method, relying on screw theory, requires less calculation effort compared with commonly used approaches.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid eye movement sleep behavior disorder (iRBD) is a prodromal state for Lewy body disorders and exhibits biological heterogeneity that may influence clinical expression and progression. We examined clinical features in individuals with iRBD and biomarker‐defined synucleinopathy.
