Onika: A Multilevel Human-Machine Interface for Real-Time Sensor-Based Systems

Navigation of an Autonomous Robot Vehicle
The U.S. Air Force has developed an autonomous excavator capable of performing a variety of tasks at various Department of Defense facilities. Common to all the tasks is the need for autonomous...

Autonomous Navigation for Structured Exterior Environments
The Telemanaged Mobile Security Station (TMSS) was developed at Sandia National Laboratories to investigate the role of mobile robotics in exterior perimeter security systems. A major...

Control Model for Robotic Backhoe Excavation and Obstacle Handling
Excavation of soil and rock is a high volume and repetitive construction operation. Robots, which are suitable for incessant and repeated manipulations, can find many potential applications....

Generalized Object Control and Assembly for Space Robots
This paper presents a Generalized Object Control framework which subsumes Unified Motion/Force Control and Object Impedance Control. Under this framework new forms of assembly primitives...

Automated Sensor Tester
The Automated Sensor Tester (AST) is being developed by Sandia National Laboratories for the Department of Energy (DOE) to be a tool to aid in testing exterior intrusion detection sensors...

Goals and Requirements for Scientific Lunar Rovers
The detailed science requirements for future lunar rovers should, of course, be based on achievable science goals and objectives. It is clear that lunar geoscience will benefit by robotic...

Generic Data Acquisition System for Robotic Waste Characterization
This paper describes a generic data acquisition system for robotic characterization of DOE production facilities and waste sites. While the specific suite of characterization sensors on...

Sensing and Control for Robotic Masonry
Due to kiln firing in the brick fabrication process, bricks vary in color, texture, and size. In an effort to automate masonry, sensing and control modules are required to ensure a normal...

Thermoelastic Theory of Cylindrical Sandwich Shells with Piezoelectric Sensors or Actuators
Cylindrical sandwich shells with piezoelectric longitudinal and ring elements bonded to the outer and inner surfaces are considered in this paper. Thermal effects are included in the analysis,...

Thermal Stresses in Piezoelectric Materials: A Boundary Integral Formulation
With the increasing use of piezoelectric materials in electromechanical devices which are often required to function in thermally hostile environment, thermal stresses and their influence...

The Potential for the Department of Defense to Use Space-Based Remote Sensing to Support DOD and Other Government Agencies' Environmental Programs
This paper describes the potential for the Department of Defense (DOD) to support other government agencies in the management of national and worldwide environmental programs. The DOD...

Integrated Spacecraft Environments Model (ISEM)
Capabilities of the ISEM code are presented that can aid in the understanding of the complex interactions between a space system and the ambient environment. The development of ISEM has...

Fiber Optic Chemical Sensors on Mars
A fiber optic chemical sensing instrument is described that will measure the reactivity of the martian soil and atmosphere. The self-contained instrument monitors reflectivity changes...

Very Low Frequency Radio Astronomy from Lunar Orbit
This paper discusses the use of very low frequency aperture synthesis as a probe of astrophysical phenomena. Specifically, the science achievable with the Lunar Observer Radio Astronomy...

Development of a High Resolution Spectrometer for Measuring the Near-Earth RFI Environment: The First Auto-Correlator in Space
A detailed description of the near-Earth RFI (radio frequency interference environment in the 0.5 - 16.5 MHz range is required before low frequency arrays can be designed and implemented...

Gravitational Wave Astronomy and the Lunar Ligo Concept
The preliminary proposal (LaFave and Wilson, 1993, 1992) for emplacing a modest LIGO [ Laser interferometer Gravitational Wave Observatory ] system on the Moon using unmanned robotic landers...

Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
