Performance Evaluation of Human Detection Systems for Robot Safety

January 22, 2016
Author(s)
William P. Shackleford, Geraldine Cheok, Tsai H. Hong, Kamel Saidi, Michael O. Shneier
Detecting and tracking people is becoming more important in robotic applications because of the increasing demand for collaborative work in which people interact closely with and in the same workspace as robots. New safety standards allow people to work

Benchmarking Robot Force Control Capabilities: Experimental Results

January 7, 2016
Author(s)
Joseph A. Falco, Jeremy A. Marvel, Richard J. Norcross, Karl Van Wyk
Metrics and test methods are needed to characterize the control capabilities of robots with both intrinsic and extrinsic force sensing. The availability of these benchmarks will motivate research product development, and provide a mechanism for reporting

A defect-driven diagnostic method for machine tool spindles

December 31, 2015
Author(s)
Gregory W. Vogl, M A. Donmez
Simple vibration-based metrics are, in many cases, insufficient to diagnose machine tool spindle condition. These metrics couple defect-based motion with spindle dynamics; diagnostics should be defect-driven. A new method and spindle condition estimation

An Industrial Control System Cybersecurity Performance Testbed

December 10, 2015
Author(s)
Richard Candell, Timothy A. Zimmerman, Keith A. Stouffer
The National Institute of Standards and Technology (NIST) is developing a cybersecurity performance testbed for industrial control systems. The goal of the testbed is to measure the performance of industrial control systems (ICS) when instrumented with

Measuring and Representing the Performance of Manufacturing Assembly Robots

Author(s)
Michael O. Shneier, Elena R. Messina, Craig I. Schlenoff, Frederick M. Proctor, Thomas Kramer, Joseph Falco
With the growth of robotic technology, there is a need for performance measures to characterize and compare robots and to help determine which features are most suited to a particular application. Robot systems are complex and involve a wide range of

Millimeter-Wave Near-Field Measurements Using Coordinated Robotics

December 1, 2015
Author(s)
Joshua A. Gordon, David R. Novotny, Ronald C. Wittmann, Michael H. Francis, Miranda L. Butler, Jeffrey R. Guerrieri
The National Institute of Standards and Technology(NIST) recently developed a new robotic scanning system for performing near-field measurements at millimeter-wave (mm-wave)frequencies above 100 GHz, the configurable robotic millimeterwave antenna (CROMMA)

A Sensor-Based Method for Diagnostics of Machine Tool Linear Axes

October 23, 2015
Author(s)
Gregory W. Vogl, Brian A. Weiss, Alkan Donmez
A linear axis is a vital subsystem of machine tools, which are vital systems within many manufacturing operations. When installed and operating within a manufacturing facility, a machine tool needs to stay in good condition for parts production. All

Adaptive Multi-scale PHM for Robotic Assembly Processes

October 23, 2015
Author(s)
Benjamin Y. Choo, Peter A. Beling, Amy LaViers, Jeremy Marvel, Brian A. Weiss
Adaptive multi-scale prognostics and health management (AM-PHM) is a methodology designed to support PHM in smart manufacturing systems. AM-PHM is characterized by its incorporation of multi-level, hierarchical relationships and PHM information gathered

Linear Temporal Logic (LTL) Based Monitoring of Smart Manufacturing Systems

October 23, 2015
Author(s)
Gerald Heddy, Umer Huzaifa, Peter A. Beling, Yacov Haimes, Jeremy Marvel, Brian A. Weiss, Amy LaViers
The vision of Smart Manufacturing Systems (SMS) includes collaborative robots that can adapt to a range of scenarios. This vision requires a classification of multiple system behaviors, or sequences of movement, that can achieve the same high-level tasks

Measurement Science for Prognostics and Health Management for Smart Manufacturing Systems: Key Findings from a Roadmapping Workshop

October 23, 2015
Author(s)
Brian A. Weiss, Gregory W. Vogl, Moneer Helu, Guixiu Qiao, Joan Pellegrino, Mauricio Justiniano, Anand Raghunathan
The National Institute of Standards and Technology (NIST) hosted the Roadmapping Workshop - Measurement Science for Prognostics and Health Management for Smart Manufacturing Systems (PHM4SMS) in Fall 2014 to discuss the needs and priorities of stakeholders

Intelligence Level Performance Standards Research for Autonomous Vehicles

October 1, 2015
Author(s)
Roger V. Bostelman, Tsai H. Hong, Elena R. Messina
U.S. and European safety standards have evolved to protect workers near Automated Guided Vehicles (AGV's). However, only recently performance standards have begun development for AGV's and mobile robots. Lessons can be learned for developing such a

Design of MEMS vision tracking system based on a micro fiducial marker

August 31, 2015
Author(s)
Yong Sik Kim, Yang Seung Ho, KwangWoong Yang, Nicholas Dagalakis
In this study, a MEMS-based vision tracking system is developed based on micro fiducial markers. The vision tracking system recognizes the predetermined patterns of the micro-scale fiducial markers and calculates the position and rotation of the MEMS

Reconfigurable Data Driven Virtual Machine Tool: Geometric Error Modeling and Evaluation

August 31, 2015

Ronnie R. Fesperman Jr., Shawn P. Moylan, Gregory W. Vogl, M A. Donmez
Standards communities are actively working to establish robust machining and measurement tests used to evaluate the machining performance of 5-axis machining centers through the direct and indirect measurement of the simultaneous motions of all five axes

Additive Manufacturing Round Robin Protocols: A Pilot Study

August 12, 2015
Author(s)
Shawn P. Moylan, Joshua Land, Antonio M. Possolo
As the number of users of additive manufacturing (AM) steadily increases, and considering their demand for material and process specifications, the need for standard protocols for round robin studies is increasing accordingly. Researchers at the National
