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 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...

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: 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
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: 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...
Briefs: Robotics, Automation & 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...
