Case Study in the Challenges of Integrating CNC Production and Enterprise Systems

December 3, 2007
Author(s)
Sid Venkatesh, B. Sides, John L. Michaloski, Frederick M. Proctor
Integration of factory floor Computer Numerical Control (CNC) information into Enterprise Resource Planning (ERP) subsystems has been difficult, if not impossible, as traditionally, factory floor machines have been islands of automation. Boeing/NIST/Okuma

Grouping Sensory Primitives for Object Recognition and Tracking

December 3, 2007
Author(s)
Rajmohan Madhavan, M Foedissch, Tommy Chang, Tsai Hong Hong
In this paper, we describe our recent efforts in grouping sensory data into meaningful entities. Our grouping philosophy is based on perceptual organization principles using gestalt hypotheses where we impose structural regularity on sensory primitives

Closed Loop CNC Manufacturing -- Connecting the CNC to the Enterprise

November 26, 2007
Author(s)
Sid Venkatesh, Rich Morihara, John L. Michaloski, Frederick M. Proctor
Closed Loop manufacturing describes the use of feedback from a Computer Numerical Control (CNC) to the Enterprise Resource Planning (ERP) to help in business operations. Although conceptually simple, many obstacles make CNC-ERP connectivity difficult -

Learning Traversability Models for Autonomous Mobile Vehicles

November 21, 2007
Author(s)
Michael O. Shneier, Tommy Chang, Tsai Hong Hong, William P. Shackleford
Autonomous mobile robots need to adapt their behavior to the terrain over which they drive, and to predict the traversability of the terrain so that they can effectively plan their paths. Such robots usually make use of a set of sensors to investigate the

Stable Navigation Solutions for Robots in Complex Environments

November 15, 2007
Author(s)
Christopher J. Scrapper Jr, Rajmohan Madhavan, Stephen B. Balakirsky
During the initial phase of a disaster response it is essential for responders to quickly and safely assess the overall situation. The use of rescue robots that can autonomously navigate and map these environments can help responders realize this goal

Design of the HLPR ChairHome Lift Position and Rehabilitation Chair

November 9, 2007
Author(s)
Roger V. Bostelman, James S. Albus
This paper is a HLPR Chair (Home Lift, Position, and Rehabilitation Chair) design document that includes a brief introduction of the need for this technology and all the mechanical and electrical designs produced to date to build this technology.

Test Methods and Knowledge Representation for Urban Search and Rescue Robots

August 17, 2007
Author(s)
Craig I. Schlenoff, Elena R. Messina, Alan M. Lytle, Brian A. Weiss, Ann M. Virts
In this paper, we described an effort in which NIST is working with FEMA Task Force members to define performance requirements and standard test methods as well as to assess the deployment potential of robots applied to the USAR domain. This process has

A Multi-Criteria Web Services Composition Problem

June 20, 2007
Author(s)
Jeong Buhwan, Hyunbo Cho, Boonserm Kulvatunyou, Albert W. Jones
With its prevalence in enterprise applications integration, the service-oriented approach has been studied in various ways. The popularity, however, results in a number of different standards and implementations. The approach needs agreed-upon definitions

Urban Search and Rescue Robot Performance Standards: Progress Update

June 15, 2007
Author(s)
Adam S. Jacoff, Elena R. Messina
In this paper, we describe work in performance standards for urban search and rescue (US&R) robots, begun in 2004 by the Department of Homeland Security. This program is being coordinated by the National Institute of Standards and Technology and will

Towards Development of an ISO Container to Spreader Bar Sensor System

June 12, 2007
Author(s)
Richard J. Norcross
This report describes a sensor system that determines the relative pose between a crane spreader and an ISO container. The sensor system supports efforts to transfer cargo between ships in high sea states under ONR s HiCASS program. The sensor system is a

Objective Test and Performance Measurement of Automotive Crash Warning Systems

April 10, 2007
Author(s)
Sandor S. Szabo, Richard J. Norcross, Joseph A. Falco
The National Institute of Standards and Technology (NIST), under an interagency agreement with the United States Department of Transportation (USDOT), is supporting development of objective test and measurement procedures for vehicle-based warning systems

Training and Optimization of Operating Parameters for Flash LADAR Cameras

April 10, 2007
Author(s)
M Price, J Kenney, Roger D. Eastman, Tsai H. Hong
Flash LADAR cameras based on continuous-wave, time-of-flight range measurement deliver fast 3D imaging for robot applications including mapping, localization, obstacle detection and object recognition. The accuracy of the range values produced depends on

A Novel Approach to Measuring Structural Similarity Between XML Documents

April 1, 2007
Author(s)
Boonserm Kulvatunyou, B Jeong, Dongjin Lee, Hyunbo Cho
Measuring structural similarity between XML documents has become a key component in various applications, including XML mining, schema matching, and web service discovery, among others. This paper presents a novel structural similarity measure

Segmentation and Classification of Human Forms Using LADAR Data

March 14, 2007
Author(s)
James S. Albus, Tsai Hong Hong, Tommy Chang
High resolution LADAR images of scenes containing human forms have been segmented and algorithms developed for recognizing human forms in various positions in both cluttered and uncluttered scenes. Registration of LADAR and color CCD images enhance the
