Improved Cast Stainless Steel Alloys

Applications include chemical/petrochemical production systems, gas turbine engines, and high-performance alloys.

At high temperatures, currently available cast stainless steel alloys used for engine component applications do not have the long-term stability of their original castings, and are lacking in their ability to resist deformation and cracking from extreme temperature changes. There is a need for high-strength, oxidation-resistant, and crack-resistant cast alloys for use in internal combustion engine components such as exhaust manifolds and turbocharger housings, gas-turbine engine components such as combustor housings, and other components that must function in extreme environments for prolonged periods of time.

Advanced Tool Drive System (ATDS) Camera Positioning Mechanism (CPM)

Robotic servicing of a satellite in low earth orbit (LEO) or geosynchronous Earth orbit (GEO) requires advanced systems capable of meeting the harsh environments of space. To support this effort, the Goddard Space Flight Center Satellite Servicing Capabilities Office (SSCO) has developed a camera positioning mechanism that will be capable of viewing features on a client satellite. Application of the CPM technology would be in multiple areas of spaceflight requiring robotic servicing including space exploration, planetary science, Earth science, and manned spaceflight.

Compact, Lightweight Trap Vent

This compact, lightweight trap vent is used to minimize the pressure differential of a high-altitude, balloon-borne detector. The vent allows the pressure to equalize rapidly, yet does not allow any light to enter the detector.

Linear Rope Brake System for Aerial Delivery

This system helps reduce loss of any supplies that are lowered to the ground.

There are instances when items (e.g., supplies) need to be lowered from an aerial vehicle to the ground. For example, the United States military often lowers supplies from a rotary winged aircraft (e.g., a helicopter) to ground troops. In some instances, there is even a need to deliver mission essential supplies to ground troops engaged in enemy combat. Rotary wing aircraft are typically the transport platform for these supplies. Many times, the aircraft cannot land, and supplies are free-dropped from as high as 150 feet above the ground. Losses of badly needed supplies such as medicine, ammunition, water, and food are high due to the free drop.

Origami-Inspired Robot Fits in Tight Spaces

The folding robot can ride aboard a rover to help explore rough terrains.

Researchers at NASA's Jet Propulsion Laboratory (JPL) were inspired by origami when they developed the Pop-Up Flat Folding Explorer Robot (PUFFER). Its lightweight design — which can hitch a ride aboard a rover — can flatten itself, tucking in its wheels and crawling into places that larger robots can't fit. Over the past year and a half, PUFFER has been tested in a range of rugged terrains, from the Mojave Desert in California to the snowy hills of Antarctica. The idea is to explore areas that might be too risky for a full-fledged rover to go, such as steep slopes or behind sand dunes.

Software Interface Simplifies Robot Control

A point-and-click method increases efficiency while decreasing errors.

The traditional interface for remotely operating robots works well for roboticists. They use a computer screen and mouse to independently control six degrees of freedom, turning three virtual rings and adjusting arrows to get the robot into position to grab items or perform a specific task. But for someone who isn't an expert, the ring-and-arrow system is cumbersome and error-prone. It's not ideal, for example, for older people trying to control assistive robots at home.

Composite C-Channel Incrementally Adjustable Fluid Control System

The system can be disassembled for relocation without much difficulty.

The ability to selectively adjust levels and flow rates in fluid control systems is a fundamental aspect of dredged material and fluid management, and necessary to numerous farm and industrial processes. Historically, fluid management structures such as gates and weirs offer limited options for controlling levels and volume. Installation is generally permanent, with modifications being difficult and expensive. Critical flow rate adjustments can be severely limited, and maintaining antiquated systems requires hazardous maneuvers dependent on extensive manpower.

Modular Climbing Robot Splits into Multiple Explorer Bots

A prototype of the Detachable Compliant Modular Robot (DCMR).

Researchers from the Robotics Research Centre at the International Institute of Technology – Hyderabad (IIIT-H), have developed a stair and obstacle climbing robot that can disassemble itself into smaller robots, and then reassemble back into one device. As a composite system, the Detachable Compliant Modular Robot (DCMR) can climb steep obstacles and staircases, and explore uneven terrain. When it detaches into multiple robots, it can explore cramped spaces, traverse flat terrain, and behave as a Multi Agent System (MAS).
