A nonlinear disturbance observer for robotic manipulators [PDF]

IEEE Transactions on Industrial Electronics, 2000
A new nonlinear disturbance observer (NDO) for robotic manipulators is derived in this paper. The global exponential stability of the proposed disturbance observer (DO) is guaranteed by selecting design parameters, which depend on the maximum velocity ...

Kinematic comparison of surgical tendon-driven manipulators and concentric tube manipulators [PDF]

Mechanism and Machine Theory, 2017
Robot manipulators are increasingly used in minimally invasive surgery (MIS). They are required to have small size, wide workspace, adequate dexterity and payload ability when operating in confined surgical cavity.

Manipulability of manipulators

Mechanism and Machine Theory, 1990
Abstract Manipulability provides a quantitative measure of the closeness of a manipulator to singularity. Arrangement of joint parameters to minimize the incidence of singularities is presented. However, restricting the joint limits will reduce the workspace and create operating barriers within the workspace for the rate control algorithm.

Manipulability analysis for mobile manipulators

Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2002
We extend the standard definition of manipulability to the case of a nonholonomic mobile manipulator built from an n joint robotic arm and a nonholonomic mobile platform. The effects of mounting the arm on a nonholonomic platform are shown through the analysis of the manipulability thus defined.
