Risk of Extreme and Catastrophic Events
Assessing the extreme tails of a probability distribution, where events of very low probability can nevertheless lead to catastrophic outcomes, is one of the most widely discussed and...
When the Levee Breaks
As repairs to the billions of dollars in damages left by the Mississippi and Missouri floods continue, many engineers believe it is time to step back and see if there are better ways of...
The Winds of Change?
In 1992, Hurricanes Andrew and Iniki combined to generate an estimated $30 billion in damage. The storms also generated their share of reports and recommendations about how best to mitigate...
Human Extender: A Material Handling System
A human's ability to perform physical tasks is limited by physical strength, not by intelligence. `Extenders' are a class of robot manipulators worn by humans to augment human mechanical...
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...
GPS-Based Control for Space Vehicle Rendezvous
The recent advent of Differential Carrier Phase Global Position System (GPS) sensing has made it possible to determine relative positions of GPS receiver-equipped systems to less than...
Navigation of Autonomous Mobile Robots
An integrated navigational system for autonomous mobile robots features a primary navigator, such as an inertial navigation or a dead-reckoning system, and a secondary navigator. The secondary...
Intelligent Excavator Control for a Lunar Mining System
The benefits of utilizing local planetary resources are a large reduction in the cost of lifting materials from the earth's surface into earth orbit. Since the moon is one of the closest...
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....
An Experiment in Mobile Robotic Cooperation
This paper describes the results of an experiment in real mobile robot cooperation which utilizes a fully distributed, cooperative software mechanism we have previously developed in simulation....
Conceptual Design and Characteristics of A Dual-Arm Cam-Lock Manipulator
Recent developments in the area of smart structures indicate that variable geometry/stiffness truss network is of fundamental importance in designing smart transformable structures and...
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...
A Stewart Platform Lunar Rover
A lunar version of the Robocrane is being developed at the Robot Systems Division of the National Institute of Standards and Technology (NIST) to address the needs of NASA researchers....
An Intelligent Robotic Vehicle for Lunar/Martian Applications
This paper describes the research effort being undertaken at UA/NASA Space Engineering Research Center (SERC) towards a general-purpose intelligent robotic vehicle system (IRVS) for Lunar...
The Optimal Selection of Robot Modules for Space Manipulators
Monolithic robot systems are poorly suited to the broad requirements and uncertainties of space automation applications. Designers have considered building many robots, each of which can...
A Novel Gravity Compensation System for Space Robots
Realistic experimental investigation of the behavior of space robots requires simulation on earth of the micro-gravity environment existing in space. This is particularly true due to the...
A Mobile Robot for Reconnaissance of HAZMAT Incident Sites
First entry into situations where hazardous materials have been accidentally spilled or released is extremely dangerous. Often the type of material, its exact location, and the extent...
URSULA: Design of an Underwater Robot for Nuclear Reactor Vessel Inspection
This paper describes the development of an underwater robotic system that will be used to perform ultrasonic inspections of nuclear reactor vessel weldments. The development effort consists...
Feasibility Analysis of Automated Material Handling for Hazardous Waste Remediation
