Autonomy Measures for Robots

November 1, 2004
Author(s)
Hui-Min Huang, Elena R. Messina, R C. Wade, W English, B Novak, James S. Albus
Robots are becoming increasingly autonomous. Yet, there are no commonly accepted terms and measures of just how autonomous a robot is. An ad hoc working group has been formed to address these deficiencies, focusing on the unmanned vehicles domain. This

Achieving intelligent performance in autonomous on-road driving

October 28, 2004
Author(s)
Craig I. Schlenoff, John Evans, Tony Barbera, James S. Albus, Elena R. Messina
This paper describes NIST?s efforts in evaluating what it will take to achieve autonomous human-level driving skills in terms of time and funding. NIST has approached this problem from several perspectives: considering the current stateof- the-art in

This paper describes NIST s efforts in evaluating what it will take to achieve autonomous human-level driving skills in terms of time and funding. NIST has approached this problem from several perspectives: considering the current state-of-the-art in

Experimental Studies of Integrated Cognitive Systems

August 26, 2004
Author(s)
P Langley, Elena R. Messina
In this paper, we examine the issues that arise in the experimental study of integrated cognitive systems. We review the reasons why such artifacts are dicult to evaluate, then consider some dependent measures that can be used to characterize their

Temporal Range Registration for Unmanned Ground and Aerial Vehicles

May 1, 2004
Author(s)
Rajmohan (. Madhavan, Tsai H. Hong, Elena R. Messina
An iterative temporal registration algorithm is presented in this paper1 for registering 3D range images obtained from unmanned ground and aerial vehicles traversing unstructured environments. We are primarily motivated by the development of 3D

Specifying Autonomy Levels for Unmanned Systems: Interim Report

April 16, 2004
Author(s)
Hui-Min Huang, James S. Albus, Elena R. Messina, R C. Wade, W English
The viability of Unmanned Systems as tools is increasingly recognized in many domains. As technology advances, the autonomy on board these systems also advances. In order to evaluate the systems in terms of their levels of autonomy, it is critical to have

Feature-Based Inspection and Control System

March 8, 2004
Author(s)
Thomas Kramer, John A. Horst, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This report describes an architecture and software system for automatically performing process planning and control code generation for cutting and inspecting prismatic piece parts. This "Feature-Based Inspection and Control System" (FBICS) consists of
