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

Temporal Range Registration for Unmanned Ground and Aerial Vehicles

November 30, 2005
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this article for registering 8 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured 9 environments. We are primarily motivated by the development of 3D

Knowledge Representation and Decision Making for Mobile Robots

July 13, 2005
Author(s)
Elena R. Messina, Stephen B. Balakirsky
Knowledge is central to a mobile robot's ability to carry out its missions and adapt to changes in the environment it is traversing. The knowledge subsystem must support acquisition of information from external sources, maintain prior knowledge, infer new

A Framework For Autonomy Levels For Unmanned Systems (ALFUS)

June 30, 2005
Author(s)
Hui-Min Huang, K Pavek, B Novak, James S. Albus, Elena R. Messina
We describe the construct of the framework for the Autonomy Levels of Unmanned Systems (ALFUS), including the ongoing development effort undertaken by the Ad Hoc working group. We describe the elements of the ALFUS framework and the process that we

Hierarchical Control and Performance Evaluation of Multi-Vehicle Autonomous Systems

May 4, 2005
Author(s)
Stephen B. Balakirsky, Christopher J. Scrapper Jr, Elena R. Messina
This paper will describe how the Mobility Open Architecture Tools and Simulation (MOAST) framework can facilitate performance evaluations of RCS compliant multi-vehicle autonomous systems. This framework provides an environment that allows for simulated

Mobility Open Architecture Simulation and Tools Environment

April 21, 2005
Author(s)
Stephen B. Balakirsky, Christopher J. Scrapper Jr, Elena R. Messina
This paper will describe the Mobility Open Architecture Tools and Simulation (MOAST) environment. This environment conforms to the NIST 4D/RCS architecture [3] and allows simulated and real architectural components to function seamlessly in the same system

Autonomy Levels for Unmanned Systems (ALFUS) Framework: An Update

April 4, 2005
Author(s)
Hui-Min Huang, K Pavek, James S. Albus, Elena R. Messina
The initial construct of the framework for the Autonomy Levels of Unmanned Systems (ALFUS) was presented in the 2004 SPIE Defense and Security Symposium. This paper describes the continuing development effort and further accomplishments made by the Ad Hoc
