Characterizing Task-Based Human-Robot Collaboration Safety in Manufacturing

February 27, 2015
Author(s)
Jeremy A. Marvel, Joseph A. Falco, Ilari Marstio
A new methodology for describing the safety of human-robot collaborations is presented. Taking a task-based perspective, a risk assessment of a collaborative robot system safety can be evaluated offline during the initial design stages. This risk

A Cross-Domain Survey of Metrics for Modeling and Evaluating Collisions

November 28, 2014
Author(s)
Jeremy A. Marvel, Roger V. Bostelman
This paper provides a brief assessment of the metrics for measuring probability, degree, and severity of collisions as applied to autonomous and intelligent systems. Though not exhaustive, this survey evaluates the state-of-the-art of collision metrics

An Additive Manufacturing Test Artifact

October 23, 2014
Author(s)
Shawn P. Moylan, John A. Slotwinski, A L. Cooke, Kevin K. Jurrens, M A. Donmez
We propose a test artifact, intended for standardization, for the purpose of evaluating the performance of additive manufacturing (AM) systems. A thorough analysis of previously proposed AM test artifacts as well as experience with machining test artifacts

Obstacle Detection and Avoidance from an Automated Guided Vehicle

September 18, 2014
Author(s)
Roger V. Bostelman, William P. Shackleford, Geraldine S. Cheok
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

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
