Manipulability Analysis for Mobile Manipulators

Manipulability of Wheeled Mobile Manipulators: Application to Motion Generation

We propose a systematic modelling of the nonholonomic mobile manipulators built from a robotic arm mounted on a wheeled mobile platform. We use the models derived to generalize the standard definition of manipulability to the case of mobile manipulators. The effects of mounting a robotic arm on a nonholonomic platform are shown through the analysis of the manipulability thus defined. Several ap...

Intelligent Behaviour Modelling and Control for Mobile Manipulators

In the last several years, mobile manipulators have been increasingly utilized and developed from a theoretical viewpoint as well as for practical applications in space, underwater, construction and service environments. The work presented in this chapter deals with the problem of intelligent behaviour modelling and control of a mobile manipulator for the purpose of simultaneously following des...

Instantaneuos kinematics and manipulability of mobile manipulators

We consider the kinematics of a mobile manipulator that consists of a non-holonomic (or holonomic) mobile platform and a holonomic manipulator mounted atop of the platform. At any fixed time instant and with fixed initial state of the platform these kinematics are viewed as a map from a Hilbert space of controls and manipulator’s joint positions into a taskspace of the mobile manipulator, and c...

On the Manipulability of Velocity-constrained Serial Robotic Manipulators

Abstract: This paper presents a performance metric for the manipulability of constrained serial manipulators. The manipulability measure and manipulability ellipsoid are found from the manipulability Jacobian, which is easily found for serial manipulators as the standard Jacobian matrix, or for parallel manipulators as the Jacobian that gives the mapping from the active joint velocities to the ...
