Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper presents a human-robot interaction system integrating a mobile manipulator with a full-body inertial motion capture suit. The framework aims to provide an intuitive, effective and easy-to-deploy teleoperation interface. User control intent is acquired by the motion capture system in real-time, processed and relayed to the mobile manipulator wirelessly. Specifically, body center of mass and the right hand kinematic data of the user are used to generate position and orientation references for the robot base and manipulator, respectively. The left arm is employed to provide high-level user commands such as "Manipulator On/Off", "Base On/Off" and "Manipulator Pause/Resume". The efficacy of the presented system was demonstrated in real-time teleoperation experiments using KUKA youBot mobile manipulator accomplishing pick-and-place tasks.
