Performance Analysis of Unmanned Vehicle Positioning and Obstacle Mapping

June 27, 2006
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan, Tommy Chang, Harry A. Scott
As unmanned ground vehicles take on more and more intelligent tasks, determination of potential obstacles and accurate estimation of their position become critical for successful navigation and path planning. The performance analysis of obstacle mapping

THE LAGR PROJECT - Integrating learning into the 4D/RCS Control Hierarchy

June 27, 2006
Author(s)
James S. Albus, Roger V. Bostelman, Tsai H. Hong, William P. Shackleford, Michael O. Shneier
The National Institute of Standards and Technology's (NIST) Intelligent Systems Division (ISD) has been a part of the Defense Advanced Research Project Agency (DARPA) LAGR (Learning Applied to Ground Robots) Project. The NIST team's objective for the LAGR

3D Range Imaging for Urban Search and Rescue Robotics Research

June 26, 2006
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan, Brian A. Weiss
Urban search and rescue (US&R) operations can be extremely dangerous for human rescuers during disaster response. Human task forces carrying necessary tools and equipment and having the required skills and techniques, are deployed for the rescue of victims

A Robot Ontology for Urban Search and Rescue

June 26, 2006
Author(s)
Craig I. Schlenoff, Elena R. Messina
The goal of this Robot Ontology effort is to develop and begin to populate a neutral knowledge representation (the data structures) capturing relevant information about robots and their capabilities to assist in the development, testing, and certification

Learning in a Hierarchical Control System: 4D/RCS in the DARPA LAGR Program

June 26, 2006
Author(s)
James S. Albus, Roger V. Bostelman, Tommy Chang, Tsai H. Hong, William P. Shackleford, Michael O. Shneier
The Defense Applied Research Projects Agency (DARPA) Learning Applied to Ground Vehicles (LAGR) program aims to develop algorithms for autonomous vehicle navigation that learn how to operate in com-plex terrain. Over many years, the National Institute of

Performance Standards for Urban Search and Rescue Robots

June 26, 2006
Author(s)
Elena R. Messina, Adam S. Jacoff
In this paper, we describe work in performance standards for urban search and rescue (USAR) 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 result

Safety Standard Advancement Toward Mobile Robot Use Near Humans

June 26, 2006
Author(s)
Roger V. Bostelman, Tsai H. Hong, Rajmohan (. Madhavan, Tommy Chang
As mobile robots have increasingly improved onboard intelligence, they are being used in more flexible manufacturing, warehouse and/or military environments where humans may intervene and interact with these robots frequently causing increased hazards. The

Towards an Approach for Knowledge-Based Road Detection

June 26, 2006
Author(s)
Mike Foedisch, Craig I. Schlenoff, Michael O. Shneier
Our previous work on road detection suggests the usage of prior knowledge in order to improve performance. In this paper we will explain our motivation for a novel approach, define requirements and point out issues, particularly concerning the

Towards an Approach for Knowledge-based Road Detection

June 26, 2006
Author(s)
Mike Foedisch, M Lochner, D Teumim
Our previous work on road detection suggests the usage of prior knowledge in order to improve performance. In this paper we will explain our motivation for a novel approach, define requirements and point out issues, particularly concerning the

Trajectory Generation for an On-Road Autonomous Vehicle

June 26, 2006
Author(s)
John A. Horst, Anthony J. Barbera
We describe an algorithm that generates a smooth trajectory (position, velocity, and acceleration) for a non-holonomic vehicle autonomously navigating within the constraints of lanes in a road. The technique models both vehicle paths and lane segments as

Using 4D/RCS to Address AI Knowledge Integration

June 26, 2006
Author(s)
Craig I. Schlenoff, James S. Albus, Elena R. Messina, Tony Barbera, Rajmohan (. Madhavan, Stephen B. Balakirsky
In this paper, we show how 4D/RCS incorporates and integrates multiple types of disparate knowledge representation techniques into a common, unifying architecture. 4D/RCS is based on the supposition that different knowledge representation techniques offer

Validating Portability of Step-NC Tool Center Programming

June 26, 2006
Author(s)
Sid Venkatesh, David Odendahl, Xun W. Xu, John L. Michaloski, Frederick M. Proctor, Thomas Kramer
A joint effort between Boeing and the National Institute of Standards and Technology (NIST) was undertaken for validating and evaluating STEP AP238 (STEP-NC) Conformance Class 1 (CC1) for 5-axis machining. STEP-NC is a new manufacturing standard to support

Entity Knowledge Model Supporting Intelligent Systems

June 20, 2006
Author(s)
Hui-Min Huang, James S. Albus, Elena R. Messina, Harry A. Scott, Maris Juberts
Intelligent systems operate in uncertain and complex environments. In order to achieve their goals, these systems require rich and updated knowledge about the environment and about their own capabilities to enable proper decision making processes. A

A Web Service-Based Reconfigurable Testbed for Business-to-Business (B2B) Integration

June 1, 2006
Author(s)
B Jeong, Jungyub Woo, Hyunbo Cho, Boonserm Kulvatunyou, James Lee
Several types of standards and corresponding software solutions have been created to enable business-to-business (B2B) integration. Testing for conformance and interoperability among these solutions are inter-dependent. This signifies the needs to make

Implementing XML Schema Naming and Design Rules

June 1, 2006
Author(s)
Joshua Lubell, Boonserm Kulvatunyou, Katherine C. Morris, Betty Harvey
We are building a methodology and tool kit for encoding XML schema Naming and Design Rules (NDRs) in a computer-interpretable fashion, enabling automated rule enforcement and improving schema quality. Through our experience implementing rules from various
