Towards a Robot Task Ontology Standard

June 8, 2017
Author(s)
Stephen B. Balakirsky, Craig I. Schlenoff, Sandro R. Fiorini, Signe Redfield, Marcos Barreto, Hirenkumar Nakawala, Joel L. Carbonera, Larisa Soldatova, Julita Bermejo-Alonso, Fatima Maikore, Paulo J. Goncalves, Elena D. Momi, S. Veera Ragavan, Tamas Haidegger
Ontologies serve robotics in many ways, particularly in describing and driving autonomous functions. These functions are built around robot tasks. The goal of a recently established international study group is to develop a knowledge representation that

ACCURACY DEGRADATION ANALYSIS FOR INDUSTRIAL ROBOT SYSTEMS

June 7, 2017
Author(s)
Guixiu Qiao, Brian A. Weiss
As robot systems become increasingly prevalent in manufacturing environments, the need for improved accuracy continues to grow. Recent accuracy improvements have greatly enhanced automotive and aerospace manufacturing capabilities, including high-precision

Building Connections through Standards Landscaping

June 7, 2017
Author(s)
Paul W. Witherell, Yan Lu
Standards are an essential part of how we do business, from communication, to establishing best practices, to achieving quality control. As commerce and technology continues to diversify, standards, and standard organizations, have become increasingly

Identification of machine tool geometric performance using on-machine inertial measurements

June 6, 2017
Author(s)
Gregory W. Vogl, Radu Pavel, Andreas Archenti, Thomas J. Winnard, Matlock M. Mennu, Brian A. Weiss, Alkan Donmez
Machine tools degrade during operations, yet accurately detecting degradation of machine components such as linear axes is typically a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the condition of

A System and Architecture for Reusable Abstractions of Manufacturing Processes

June 2, 2017
Author(s)
Alexander Brodsky, Mohan Krishnamoorthy, William Z. Bernstein, M. Omar Nachawati
In this paper we report on the development of a system for managing a repository and conducting analysis and optimization on manufacturing performance models. The repository is designed to contain (1) unit manufacturing process performance models, (2)

Channel Modeling and Performance of Zigbee Radios in an Industrial Environment

May 31, 2017
Author(s)
Mehrdad Damsaz, Derek Guo, Jeff Peil, Wayne Stark, Nader Moayeri, Rick Candell
In this paper we describe measurements of wireless propagation characteristics to develop path loss models in industrial environments. The models for path loss we develop are two-slope models in which the path loss is a piecewise linear relation with the

Automated Uncertainty Quantification Through Information Fusion in Manufacturing Processes

May 12, 2017
Author(s)
Saideep Nannapaneni, David Lechevalier, Anantha Narayanan Narayanan, Sankaran Mahadevan, Sudarsan Rachuri
Evaluation of key performance indicators (KPIs) such as energy consumption is essential for decision-making during the design and operation of smart manufacturing systems. The measurements of KPIs are strongly affected by several uncertainty sources such
