Robots with manipulator arms, or mobile manipulators, are useful in a variety of applications, such as Explosive Ordinance Disposal (EOD) or Urban Search and Rescue (USAR). However, the systems currently being fielded are relatively primitive. This work demonstrates an improved mobile manipulator system which includes several technologies for more intelligent teleoperation. “Click and Grab” is ...

Finding the full load motion for a point-to-point task can maximize the productivity and economic usage of the mobile manipulators. The presented paper proposes a technique to determine the maximum allowable dynamic payload for flexible mobile manipulators along with the obtained optimal trajectories. Non-linear modeling of the mobile robotic manipulators by considering both link and joint flex...

Introduction: Integrated radiation therapy - MRI systems are capable of delivering high doses to the target tissues near sensitive organs and achieve better therapeutic results; however, the Applied magnetic fields for imaging, can influence the charged path, change the penetration depth and deflect the particles, laterally, leading to dose distribution variations. Therefore, i...

This paper presents the application of an image registration method for a mobile manipulator. The robot is used for scanning natural terrain and detecting metal objects hidden beneath the terrain surface (e.g., landmines) using a metal detector. The range image may be interpreted for visual servoing, map building and path planning, or object recognition. In this work, the image is used to build...

A new type of range searching problem, called the partial enclosure range searching problem, is introduced in this paper. Given a set of geometric objects S and a query region Q, our goal is to identify those objects in S which intersect the query region Q by at least a fixed proportion of their original size. Two variations of this problem are studied. In the first variation the objects in S a...

BACKGROUND Hand, foot, and mouth disease (HFMD) is known to be a highly contagious childhood illness. In recent years, the number of reported cases of HFMD has significantly increased in mainland China. This study aims at the epidemiological features, spatiotemporal patterns of HMFD at the county/district level in mainland China. METHODS Data on reported HFMD cases for each county from 1 Janu...

Kennzahlensysteme sind im Zusammenspiel mit Kennzahlenbzw. Performancedashboards zu wichtigen Steuerungsunterstützungssystemen in Unternehmen geworden. Diese Arbeit zeigt die Limitierung herkömmlicher Kennzahlendashboards auf die mathematisch-logische Verdichtung von Informationen im Kontext eines Kennzahlensystems auf und stellt eine Erweiterung von Kennzahlendashboards um semantische Informat...

The integration of constraint solvers into proof planning has pushed the problem solving horizon. Proof planning beneets from the general functionalities of a constraint solver such as consistency checks, constraint inference, as well as the search for instantiations. However, oo-the-shelf constraint solvers are usually geared towards their typical applications. Since proof planning diiers from...

GIPO IV is an experimental environment for planning domain knowledge engineering. The purpose of the tool is to demonstrate the range and scope of tools required to support the knowledge engineering aspects of planning systems creation. In particular GIPO provides support for the encoding and validation of planning domain knowledge, for both classical pre-condition planning and hierarchical pla...
