Knowledge Engineering for Real Time Intelligent Control

December 31, 2003
Author(s)
Elena R. Messina, James S. Albus, Craig I. Schlenoff, J L. Evans
The key to real-time intelligent control lies in the knowledge models that the system contains. We argue that there needs to be a more rigorous approach to engineering the knowledge within intelligent controllers. Three main classes of knowledge are

Test Arenas and Performance Metrics for Urban Search and Rescue Robots

October 31, 2003
Author(s)
Adam S. Jacoff, Elena R. Messina, Brian Weiss, S Tadokoro, Y Nakagawa
In this paper, we discuss the development and proliferation of robot test arenas that provide tangible, realistic, and challenging environments for mobile robot researchers interested in urban search and rescue applications and other unstructured

Design and Workspace Analysis of a 6-6 Cable-Suspended Parallel Robot

October 1, 2003
Author(s)
H C. Pusey, A Fattah, S K. Agrawal, Elena R. Messina, Adam S. Jacoff
In this paper, we study the design and workspace of a 6-6 cable-suspended parallel robot. The workspace volume is characterized as the set of points where the centroid of the MP (MP) can reach with tensions in all suspension cables at a constant

Information-Based Intelligent Unmanned Ground Vehicle Navigation

October 1, 2003
Author(s)
Rajmohan Madhavan, Elena R. Messina
Sensor-centric navigation of Unmanned Ground Vehicles (UGVs) operating in rugged and expansive terrains requires the competency to evaluate the utility of sensor information such that it results in intelligent behavior of the vehicles. In this paper, we

Evolution of a Performance Metric for Urban Search and Rescue Robots (2003)

September 30, 2003
Author(s)
Adam S. Jacoff, Brian A. Weiss, Elena R. Messina
This paper discusses the advancement and proliferation of the Reference Test Arenas for Urban Search and Rescue Robots as representative search and rescue environments, which allow objective performance evaluation of mobile robot capabilities. These arenas

Intelligent Systems for Urban Search and Rescue: Challenges and Lessons Learned

September 1, 2003
Author(s)
Adam S. Jacoff, Elena R. Messina, Brian A. Weiss
Urban search and rescue (USAR) is one of the most dangerous and time-critical non-wartime activities. Researchers have been developing hardware and software to enable robots to perform some search and rescue functions so as to minimize the exposure of
