Benchmarking and Standardization of Intelligent Robotic Systems

March 18, 2010
Author(s)
Rajmohan Madhavan, R Lakaemper, Tamas Kalmar-Nagy
From mundane and repetitive tasks to assisting first responders in saving lives of victims in disaster scenarios, robots are expected to play an important role in our lives in the coming years. Despite recent advances in mobile robotic systems, lack of

Performance Measures Framework for Unmanned Systems (PerMFUS): Initial Perspective

February 18, 2010
Author(s)
Hui-Min Huang, Elena R. Messina, Adam S. Jacoff
The performance of intelligent unmanned systems (UMS) must be able to be measured to ensure that they can meet the operational requirements. A generic framework to enable capturing and organizing the performance metrics are highly desirable. In this

Complete Inspection: In-situ system to inspect 100% of micro-parts

February 1, 2010
Author(s)
Shawn P. Moylan
On-machine measurement can provide significant advantages in part metrology at the micro/meso-scale. The strengths of measurement by fringe projection techniques directly address the difficulties presented by on-machine measurement. An experimental setup

Roger D. Eastman, Tsai H. Hong, Jane Shi, Tobias Hanning, Bala Muralikrishnan, S. S. Young, Tommy Chang
Real-time three-dimensional vision has been rapidly advancing over the past twenty years, leading to a number of successful laboratory demonstrations, including real-time visual servoing, autonomous vehicle navigation , and real-time people and vehicle

Evaluation of RoboCup Maps

December 17, 2009
Author(s)
Stephen B. Balakirsky, Benjamin Balaguer, Stefano Carpin, Arnoud Visser
This paper describes the steps taken to create the score criteria aimed at measuring the quality of maps produced by teams participating in the RoboCup Rescue Virtual Robots competition. Since metrics have already been developed by a few research groups

From Simulation to Real Robots with Predictable Results: Methods and Examples

December 1, 2009
Author(s)
Stephen B. Balakirsky, Stefano Carpin, George Dimitoglou, Benjamin Balaguer
From a theoretical perspective, one may easily argue (as we will in this chapter) that simulation accelerates the algorithm development cycle. However, in practice many in the robotics development community share the sentiment that "Simula-tion is doomed

Performance Measurements Towards Improved Manufacturing Vehicle Safety

November 23, 2009
Author(s)
Roger V. Bostelman, William P. Shackleford
In this paper, we describe the current 2D (dimensional) sensor and ideal sensor configurations if 3D imagers are mounted on manufacturing vehicles in an attempt to make them more safe. Towards the ideal sensor configuration, three experiments were

Mobile Microrobot Characterization through Performance-Based Competitions

November 19, 2009
Author(s)
Jason J. Gorman, Craig D. McGray, Richard A. Allen
Recent advances in the design and fabrication of microelectromechanical systems (MEMS) have enabled the development of mobile microrobots that can autonomously navigate and manipulate in controlled environments. It is expected that this technology will be

Interoperability and the DMIS experience

October 30, 2009
Author(s)
John A. Horst
Because they enable true interoperability, information exchange standards can help manufacturers reduce cost and improve product quality, but only if the standards are developed and implemented correctly. We will answer questions manufacturers and

Mathematical Metrology for Evaluating a 6DOF Visual Servoing System

October 8, 2009
Author(s)
Tommy Chang, Tsai H. Hong, Milli Shah, Roger D. Eastman
In this paper we develop the best homogeneous matrix trans- formation to fit two streams of dynamic six-degree-of-freedom (6DOF) data for evaluating perception systems using ground truth. In particular, we compare object position and orien- tation results

Quantitative Assessment of Robot-generated Maps

October 8, 2009
Author(s)
Christopher J. Scrapper Jr, Rajmohan Madhavan, Adam S. Jacoff, R Lakaemper, A Censi, Afzal A. Godil, Asim Wagan
Mobile robotic mapping is now considered to be a sufficiently mature field with demonstrated successes in various domains. While there has been much progress made in the development of computationally efficient and consistent mapping schemes, it is still

Measurement Traceability and Quality Assurance in a Nanomanufacturing Environment

September 25, 2009
Author(s)
Ndubuisi G. Orji, Ronald G. Dixson, Aaron Cordes, Benjamin Bunday, John Allgair
A key requirement for nano-manufacturing is maintaining acceptable traceability of measurements performed to determine size. Given that properties and functionality at the nanoscale are governed by absolute size, maintaining the traceability of dimensional

Impact of automation on precision

August 3, 2009
Author(s)
M A. Donmez, Johannes A. Soons
Automation has significant impacts on the economy and the development and use of technology. In this section, the impacts of automation on precision, which directly influences science, technology, and the economy, are discussed. As automation enables

Uncertainty Analysis of a Simple Fringe Projection System

July 1, 2009
Author(s)
Shawn P. Moylan, Gregory W. Vogl
Fringe projection is an optical method of measuring the surface profile of a part. Most basic fringe projection processes require an initial calibration step to determine components of coordinate transformation matrices before the surface point coordinates

Robots to the Rescue

June 30, 2009
Author(s)
Elena R. Messina
Despite current limitations, robots can still play a significant role in helping the response community by being their eyes and ears in dangerous, unknown, or difficult-to-access locations. This article describes how the National Institute of Standards and

Advancing Manufacturing Research Through Competitions
