New AGV Capabilities are Safety Driven

September 3, 2014
Author(s)
Roger V. Bostelman, William P. Shackleford
Current automated guided vehicle (AGV) technology typically provides material handling flow along single or dual opposing-flow lanes in manufacturing and distribution facilities. An AGV stops for most any obstacle that may be in its path which then stops

Performance Metrics for Evaluating Object and Human Detection and Tracking Systems

July 30, 2014
Author(s)
Afzal A. Godil, Roger Bostelman, William P. Shackleford, Tsai H. Hong, Michael O. Shneier
In this report, we provide an overview of various performance evaluation metrics for object detection and tracking for robot safety applications in smart manufacturing. We present four different types of performance evaluation metrics based on detection

Safety and Performance Standard Developments for Automated Guided Vehicles

July 23, 2014
Author(s)
Roger V. Bostelman, Tsai H. Hong, Roger D. Eastman
The American National Standards Institute/Industrial Truck Standards Development Foundation (ANSI/ITSDF) B56.5 Safety Standard committee for automated guided vehicles (AGVs) has been considering several changes to improve the standard. Of interest to the

Control Fusion for Safe Multi-robot Coordination

May 9, 2014
Author(s)
Roger V. Bostelman, Jeremy A. Marvel
Future smart manufacturing systems will include more complex coordination of mobile manipulators (e.g., robot arms mounted on mobile bases). The National Institute of Standards and Technology, Performance of Collaborative Robot Systems Project has been

A Roadmap to Advance Measurement Science in Robot Dexterity and Manipulation

May 1, 2014
Author(s)
Joseph A. Falco, Jeremy A. Marvel, Elena R. Messina
In order for robots to expand their applicability within manufacturing operations, their dexterity needs to advance considerably. There is active research in many areas that is contributing to creating a new generation of much more dexterous arms and hands

Powder Bed Fusion Machine Performance Testing

April 16, 2014
Author(s)
Shawn P. Moylan, Joseph Drescher, M A. Donmez
Unlike conventional machining where there is a near 1:1 correspondence of machine performance to the geometry of the workpiece, the accuracy of the machine components is only one of the contributors to the quality of a finished AM part. Rather, there is

Study of Accuracy of Parts Produced Using Additive Manufacturing

April 16, 2014
Author(s)
Marcin Bauza, Shawn P. Moylan, Robert Panas, Stephen Burke, Harry Martz, John S. Taylor, Paul Alexander, Richard Knebel
The purpose of this presentation is to focus discussion onto the issue of accuracy and uncertainty of parts made with additive manufacturing processes.

Methods for improving visibility measurement standards of powered industrial vehicles

February 28, 2014
Author(s)
Roger V. Bostelman, Jochen Teizer, Soumitry J. Ray, Mike Agronin, Dominic Albanese
Poor visibility of powered industrial vehicles, such as forklifts, used in industry is often the cause of accidents that include pedestrians. Current standards allow up to 20% non-visible regions for forklifts where measurement of these regions is

An Ontology Based Approach to Action Verification for Agile Manufacturing

January 10, 2014
Author(s)
Zeid Kootbally, Stephen B. Balakirsky
Many of today's robotic work cells are unable to detect when an action failure has occurred. This results in faulty products being sent down the line, and/or downtime for the cell as failures are detected and corrected. This article examines a novel

A Simulated Sensor-based Approach for Kit Building Applications

December 20, 2013
Author(s)
Zeid Kootbally, Craig I. Schlenoff, Theodore J. Weisman, Stephen B. Balakirsky, Thomas R. Kramer, Anthony Pietromartire
Kit building or kitting is a process in which individually separate but related items are grouped, packaged, and supplied together as one unit (kit). This paper describes advances in developing sensing/control and parts detection technologies enabling

Preface: Ubiquitous Robotics (UBIROBOTS): Workshop at the UBICOMP 2012 Conference

November 30, 2013
Author(s)
Craig I. Schlenoff, Edson Prestes, Abdelghani Chibani, Yacine Amirat
Ubiquitous robots (UBIROBOTS) are smart software or physical service providers within ambient intelligence environments. The integration of these robots within cloud computing and ubiquitous computing technologies will enhance our daily lives. Ubiquitous

Methods for Performance Evaluation of Single Axis Positioning Systems: A New Standard

October 25, 2013
Author(s)
Ronnie R. Fesperman Jr., Nathan Brown, Kevin Elliott, Jonathan D. Ellis, Axel Grabowski, Steve Ludwick, Serge Maneuf, Brian O'Connor, Shane Woody
Many new high-precision linear and angular positioning systems are being used in emerging micro- and nanotechnology applications. Measuring and certifying the performance of these systems with off-the-shelf instrumentation and test methods suggested by

Towards Mobile Manipulator Safety Standards

October 24, 2013
Author(s)
Jeremy A. Marvel, Roger V. Bostelman
We present an overview of the current safety standards for industrial robots and automated guided vehicles (AGVs), and describe how they relate to the safety concerns of mobile manipulators (robot arms mounted on mobile bases) in modern manufacturing

A Literature Review of Sensor Ontologies for Manufacturing Applications

October 23, 2013
Author(s)
Craig I. Schlenoff, Tsai Hong Hong, Roger D. Eastman
The purpose of this paper is to review existing sensor and sensor network ontologies to understand whether they can be reused as a basis for a manufacturing perception sensor ontology, or if the existing ontologies hold lessons for the development of a new

Challenges of the Changing Robot Markets

July 19, 2013
Author(s)
Gurvinder S. Virk, Carol Herman, Roger V. Bostelman, Tamas Haidegger
Service robots are becoming an integrated part of daily life, entering even the most complex scenarios, yet at a slower pace than previously anticipated. This paper presents an overview of the changing area of robotics and the new challenges being faced
