Directional Manipulability for Motion Coordination of an Assistive Mobile Arm

International audienceIn this paper, we address the problem of coordinated motion control of a manipulator arm embarked on a mobile platform. The mobile manipulator is used in providing assistance for disabled people. In order to perform a given task by using mobile manipulator redundancy, we propose a new manipulability measure that incorporates both arm manipulation capacities and the end-effector imposed task. This proposed measure is used in a numerical algorithm to solve system redundancy and then compared with other existing measures. Simulation and real results show the benefit and efficiency of this measure in the field of motion coordination

Kinematics and Robot Design IV, KaRD2021

This volume collects the papers published on the special issue “Kinematics and Robot Design IV, KaRD2021” (https://www.mdpi.com/journal/robotics/special_issues/KaRD2021), which is the forth edition of the KaRD special-issue series, hosted by the open-access journal “MDPI Robotics”. KaRD series is an open environment where researchers can present their works and discuss all the topics focused on the many aspects that involve kinematics in the design of robotic/automatic systems. Kinematics is so intimately related to the design of robotic/automatic systems that the admitted topics of the KaRD series practically cover all the subjects normally present in well-established international conferences on “mechanisms and robotics”. KaRD2021, after the peer-review process, accepted 12 papers. The accepted papers cover some theoretical and many design/applicative aspects
