Abstract: In this work, a family of two degrees of freedom (2DOF) rotational parallel manipulators (RPMs) with an equaldiameter spherical pure rotation (ESPR) is presented and discussed systematically. The theoretical models of both ...

Abstract: Twodegreeoffreedom (2DOF) pointing mechanisms have been widely used in areas such as stabilized platforms, tracking devices, etc. Besides the commonly used serial gimbal structures, another two types of parallel pointing ...

Abstract: A leaf-type isosceles-trapezoidal flexural pivot can be of great practical use for designing compliant mechanisms. The analysis of load-deflection behavior for such a pivot is essential to the ...

Abstract: An isosceles-trapezoidal flexural pivot can be of great use for practical designs, especially in the cases that a pure rotation about a virtual pivot is required. The analysis of rotational ...
