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 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...
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...
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....
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...
An Overview of the Accident Response Mobile Manipulation System (ARMMS)
The development of a high mobility platform integrated with high strength manipulation is under development at Sandia National Laboratories. The mobility platform used is a High Mobility...
Robotic Workcell for Waste Handling
During the sorting and repackaging of recovered waste, robotic systems for grasping and manipulating odd-shaped objects of varying sizes will be needed. Also, during the removal of buried...
Bubba, A Teleoperated Countermine Vehicle
A recent countermine test program required the development of Bubba, a 5 ton, 6 wheel drive, M-923 military truck converted to teleoperation. The Mine Detection by Energetic Photons (MIDEP)...

On the Dynamics and Control of Flexible Orbiting Systems: An Approach with Application
A relatively general formulation for studying the dynamics and control of an arbitrary spacecraft, with interconnected flexible, deployable and articulating structural members, is reviewed...
Improving Dynamic Finite Element Models Using Test Data
A structural optimization based method was developed to improve the finite element model to achieve good agreement with the test results. The modal displacements at critical locations...
Large Deformation Theory Using Truncated Rotations
Today's aerospace industry has advanced to the point of using optimum design techniques in virtually all applications. In structural elements, orthotropic fiber composite materials have...
A New Airlock Approach for Human Exploration
Conceptual design work on the First Lunar Outpost (FLO) mission led to the development of an airlock concept called the `doorlock' which appears quite promising for all aspects of manned...
Mechanics of Curved Fiber Bundles in Composites
Fiber undulations are inherent to manufacturing processes like braiding and filament-winding, and sometimes occur as defects in other composite structures. This paper summarizes the status...
