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

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

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

Experiments Toward Non-Contact Safety Standards for Automated Industrial Vehicles

April 1, 2005
Author(s)
Roger V. Bostelman, Tsai Hong Hong, Rajmohan Madhavan
The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a new 3D real-time range camera is the subject of this paper. Our approach expands on the US

The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a 3D real-time range camera is the subject of this paper. Our approach has been tested

Self-contained automated construction deposition system

December 31, 2004
Author(s)
R L. Williams, James S. Albus, Roger V. Bostelman
This article presents a novel autonomous system concept for automated construction of houses and other buildings via deposition of concrete and similar materials. The overall system consists o f a novel cable-suspended mobility subsystem (a selfcontained

Seven-DOF Cable-Suspended Robot with Independent Metrology

October 4, 2004
Author(s)
R L. Williams, B Snyder, James S. Albus, Roger V. Bostelman
This paper presents a new cable-suspended robot. It is a 7-cable spatial design with a closed-form forward pose kinematics solution. Applications include automated machining, construction, and sculpting. This paper presents two new ideas. First, an

3D Cable-Based Cartesian Metrology System

December 31, 2003
Author(s)
R L. Williams, James S. Albus, Roger V. Bostelman
A novel cable-based metrology system is presented wherein six cables are connected in parallel from groundmounted string pots to the moving object or tool of interest. Cartesian pose can be determined for feedback control and other purposes by reading the
