The unmanned aerial vehicle (UAV) accelerometer is a sensor that measures the
acceleration of the UAV by detecting the components of gravity along the three axes. The …

Dimensional synthesis is a type of inverse problem in linkage kinematics where the
objective is to calculate the linkage dimensions required to achieve prescribed linkage …

The optimal dimensional synthesis for Stephenson III six-bar linkages, planar and spherical,
is presented. The requirement for dwells of the output link and the path generation task are …

A wavelet feature parameters method is proposed for the non-periodic design requirements
in the path synthesis of a spherical four-bar linkage mechanism. A mathematical model for …

The local and global geometric properties of spherical coupler curves constitute spherical
kinematics of spherical four-bar linkages, which can be adopted to reveal distribution …

This contribution proposes a new formulation to efficiently compute directional derivatives of
order one to fourth. The formulation is based on automatic differentiation implemented with …

According to the burmester theory, an infinite number of spherical or planar 4R linkages for a
specific four-orientation task can be synthesized, but most of the linkage solutions calculated …

In this work, the kinematics of a spherical parallel manipulator composed of three peripheral
limbs equipped with linear actuators and a passive center shaft is approached by means of …

In this paper, a novel analytical approach for synthesizing a path-generation mechanism of
spherical four-bar mechanism without any limitation on the number of precision points is …

In this study, the authors propose a solutions map based on a telomere genetic algorithm
(TGA) to improve the efficiency of 4R-linkage synthesis. First, the points on the center curve …
