A novel multidimensional uncalibration method applied to six-axis manipulators

open access: yesFrontiers in Neuroscience, 2023
This study proposes a multidimensional uncalibrated technique for tracking and grasping dynamic targets by a robotic arm in the eye-in-hand mode. This method avoids complex and cumbersome calibration processes, enabling machine vision tasks to be ...

Unscented Particle Filter for Online Total Image Jacobian Matrix Estimation in Robot Visual Servoing

open access: yesIEEE Access, 2019
The main purpose of visual servoing is to control the motion of a robot system based on visual information provided by one or more cameras. It is an important research topic in the robotics community.

Iterative Solutions to the Inverse Geometric Problem for Manipulators with no Closed Form Solution [PDF]

open access: yesModeling, Identification and Control, 2008
A set of new iterative solutions to the inverse geometric problem is presented. The approach is general and does not depend on intersecting axes or calculation of the Jacobian.

The jacobian problem for singular surfaces

open access: yesKyoto Journal of Mathematics, 2008
We consider normal affine surfaces $X$ with étale endomorphisms. It is proved that if $X$ has at least one singular point which is not a quotient singular point then such an endomorphism is an isomorphism.

A numerical solution of parabolic quasi-variational inequality nonlinear using Newton-multigrid method [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization
In this article, we apply three numerical methods to study the L∞-convergence of the Newton-multigrid method for parabolic quasi-variational inequalities with a nonlinear right-hand side.

An Adaptive Second Order Sliding Mode Inverse Kinematics Approach for Serial Kinematic Chain Robot Manipulators

open access: yesRobotics, 2020
The problem of inverse kinematics is essential to consider while dealing with the robot’s mechanical structure in almost all applications. Since the solution of the inverse kinematics problem is very complex, many research efforts have been working

Retrieving 3D distributions of atmospheric particles using Atmospheric Tomography with 3D Radiative Transfer – Part 1: Model description and Jacobian calculation [PDF]

open access: yesAtmospheric Measurement Techniques, 2023
Our global understanding of clouds and aerosols relies on the remote sensing of their optical, microphysical, and macrophysical properties using, in part, scattered solar radiation.

Long step homogeneous interior point algorithm for the p* nonlinear complementarity problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2002
A P*-Nonlinear Complementarity Problem as a generalization of the P*-Linear Complementarity Problem is considered. We show that the long-step version of the homogeneous self-dual interior-point algorithm could be used to solve such a problem.

A Method for Directly Extracting the Jacobian Matrix of the Power Flow Equations of a Power System in Polar Coordinates

open access: yesFrontiers in Energy Research, 2022
This paper presents a method to directly extract the Jacobian matrix of a power system’s power flow (PF) equations in polar coordinates (termed as DEJMP method). This method is designed to reduce the computational complexity of the extraction process and
