Sounding Out Scour
As engineers are aware, detection of bridge scour is the best protection. A method for monitoring scour during low, normal or high water flows would also help alleviate some of the ambiguity...
Journal of Architectural Engineering
The Journal of Architectural Engineering provides a multidisciplinary forum for dissemination of research-based engineering and technical information related to all aspects of building engineering design...
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...
I.P.L. Space Trusses: Structural Performance and Analysis
The utilization of the fast working massively parallel computers in solving intense numerical problems, in the field of structural engineering left disappointed many of practical engineers....
The Role of Computer Graphics in Teleoperation
Computer graphics techniques developed by the Advanced Teleoperation (ATOP) Project at the Jet Propulsion Laboratory (JPL) for the control of remote manipulators, primarily for space applications,...
Real-time Motion Vision for Robot Control in Unstructured Environments
The control of robots in unstructured environments demands real-time, general purpose vision. We have designed a visual tracking system which makes use of motion to pick out and track...
Application of Virtual Reality to Space Robotics Operations
This paper discusses a Virtual Reality (VR) simulation under development by the Automation and Robotics (A&R) Division at the Johnson Space Center (JSC). Over the past twelve years,...
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...
