A cooperative paradigm for task-space control of multilateral nonlinear teleoperation with bounded inputs and time-varying delays
Download2022-11-03
Amir Zakerimanesh, Farzad Hashemzadeh, Ali Torabi, Mahdi Tavakoli
In this article, a novel multilateral teleoperation structure is presented for cooperative control of a redundant remote robot in the task-space. In the structure, each local robot is assigned a real number between zero and one, as its dominance factor. The sum of all the assigned factors is...

Amir Zakerimanesh, Farzad Hashemazdeh, Ali Torabi, Mahdi Tavakoli
This paper introduces a novel control framework for bilateral teleoperation system with the redundant remote robot to ensure the end-effectors’ position tracking while satisfying a sub-task control such as obstacle avoidance in the presence of the nonlinear dynamics for the manipulators and...

Improving a User's Haptic Perceptual Sensitivity by Optimizing Effective Manipulability of a Redundant User Interface
Download2022-11-03
Teng Li, Ali Torabi, Hongjun Xing, Mahdi Tavakoli
ABSTRACT: Human perceptual sensitivity of various types of forces, e.g., stiffness and friction, is important for surgeons during robotic surgeries such as needle insertion and palpation. However, force feedback from robot end-effector is usually a combination of desired and undesired force...
