Briefs: Robotics, Automation & Control
Microscopic forced-flow heat-transfer systems containing heat exchangers, flow channels, electrostatically driven peristaltic pumps, and related components have been proposed. These...
Briefs: Robotics, Automation & Control
The figure illustrates various aspects of a proposed mechanism that would be mounted in an instrumented penetrator dart for use in acquiring a sample of soil. In operation, the dart would be...
Briefs: Robotics, Automation & Control
The Eclipse flight project was established to demonstrate a reusable-launch-vehicle concept developed by Kelly Space and Technology, Inc. An F-106 delta-wing aircraft was chosen as the towed...
Briefs: Robotics, Automation & Control
Lightweight, inflatable robotic vehicles (rovers) that superficially resemble beach balls and that could be driven by wind and/or electric power are undergoing development. These rovers were conceived...
Briefs: Robotics, Automation & Control
An aircraft control actuator that incorporates self-contained control electronics has been installed in the F-18 Systems Research Aircraft and evaluated in flight tests. This "smart" actuator...
Briefs: Robotics, Automation & Control
An improved hybrid thermal/mechanical system has been developed to protect airplane wings and other airfoils against the accretion of ice, which degrades aerodynamic performance. The...
Briefs: Robotics, Automation & Control
Research conducted at the Pittsburgh Research Center (formerly U.S. Bureau of Mines) developed technology that will allow computer-assisted operation of mechanized equipment normally used in...
Briefs: Motion Control
Mobile robots that would resemble earthworms have been proposed for use in exploring remote, hostile, or inaccessible terrain surface and subsurface environments. This class of robots would be a special case of...

Micromachined Monopropellant Thrusters
A report proposes monopropellant microthrusters for a new generation of miniature spacecraft with mission lifetimes stretching into years. These thrusters would include micromachined nozzle/chamber assemblies containing microvalves, designed according to emerging concepts of microelectromechanical systems...
Briefs: Robotics, Automation & Control
An electromagnetic shaker based on a linear induction motor has been developed for use in flight flutter testing of aircraft. The shaker is a wing-tip-mounted unit capable of delivering...

Solar-Powered Aerobots With Power-Surge Capabilities
Advanced aerobots that would be powered by solar photovoltaic batteries and that would be capable of storing energy for occasional operation during short intervals at power levels far beyond those of the photovoltaic batteries have been proposed. Aerobots are robotic balloon-buoyed airborne...
Briefs: Robotics, Automation & Control
In-situ resource utilization (ISRU) equipment would be incorporated into remotely controlled exploratory robots, according to a proposal, to generate fuels and oxidizers to extend...
Briefs: Robotics, Automation & Control
An analysis of empirical data on low-frequency oscillations in the inlet flow of a turbopump has led to the conclusion that these oscillations could be reduced or eliminated with suitable...
Briefs: Aerospace
Adaptive performance optimization (APO) is an approach for improving aircraft performance without the need for extensive modifications of hardware. In this approach, one exploits existing...
Briefs: Robotics, Automation & Control
Development of Small, Mobile, Special-Purpose Robots
A report presents a scenario for the proposed development of insectlike robots that would be equipped with microsensors and/or micromanipulators, and would be designed, variously, to crawl, burrow, swim, fly, or hop, to perform specific tasks in fields as diverse as exploration,...
Briefs: Motion Control
A small prototype robotic all-terrain vehicle features a unique drive and suspension system that affords capabilities for self righting, pose control, and enhanced maneuverability for...
Briefs: Robotics, Automation & Control
A prototype manipulator system that includes two different arms has been tentatively selected for use on a semiautonomous robotic vehicle called Rocky 7 (see figure). [A previous version of this vehicle...
