Engineers Develop 'Simple' Robotic Swarms

University of Sheffield engineers have developed a way of making hundreds — or even thousands — of tiny robots cluster to carry out tasks. The robots do not require memory or processing power. Each robot uses just one sensor that indicates the presence of another nearby robot. Based on the sensor's findings, the robots will either rotate on the spot, or move around in a circle until one can be seen.Until now, robotic swarms have required complex programming, complicating the development of miniaturized, individual robots. With the programming created by the Sheffield team, however, nanoscale machines are possible.SourceAlso: Learn about a Kinematic Calibration Process for Flight Robotic Arms.

Will "Flying Cars" Become a Reality?

A Boston-based aerospace company Terrafugia announced last year that it began work on its TF-6, a four-seat hybrid electric car that can do vertical take-offs and landings. The vehicle has foldable wings, cruises at 100 miles per hour, fits inside a single-car garage, and drives at highway speeds. With the new prototype, Terrafugia believes that users can learn to operate the TF-X in just five hours. Users will have to learn how to interface with the vehicle; how to determine if it's safe to take off and land; and when to activate the vehicle's parachute system in the event of an emergency.

Switchable Material Absorbs and Stores Sun's Energy

A team at MIT and Harvard University has created a material that absorbs the sun’s heat and stores that energy in chemical form, ready to be released again on demand.The technology provides an opportunity for the expansion of solar power into new realms, specifically applications where heat is the desired output.“It could change the game, since it makes the sun’s energy, in the form of heat, storable and distributable,” says Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT.SourceAlso: See other Materials tech briefs.

In The Near Future, Will 3D Printers Be Used To Create Human Organs?

3D printers, an emerging technology, use computer-created digital models to produce a variety of objects, including toys, mechanical components, and even food. There is hope now, too, that 3D printers could someday create much-needed organs for transplants. Printing human organs is still years away, but many medical professionals are optimistic and see great promise with the technology. A major challenge will be the ability to create the material, which is biological in nature.

Remote Sensing Moisture Model Could Aid Farmers

Global farmers could get better decision-making help as refinements are made to North Alabama soil moisture modeling research being done by an atmospheric science doctoral student at The University of Alabama in Huntsville. The models indicate how much added moisture would be needed in a given area versus historical data to achieve various crop yields, and they could aid in making expensive infrastructure investments by helping to determine their economic viability.

NASA Radar Demonstrates Ability to Predict Sinkholes

New analyses of NASA airborne radar data collected in 2012 reveal that radar detected indications of a huge sinkhole before it collapsed and forced evacuations in Louisiana that year. The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they happen, decreasing danger to people and property.

NASA Model Provides 3-D View of L.A. Earthquake

On March 28, residents of Greater Los Angeles experienced the largest earthquake to strike the region since 2008. The magnitude 5.1 quake was centered near La Habra in northwestern Orange County about 21 miles (33 kilometers) east-southeast of Los Angeles, and was widely felt throughout Southern California. There have been hundreds of aftershocks, including one of magnitude 4.1.Scientists at NASA's Jet Propulsion Laboratory, Pasadena, Calif., have developed a model of the earthquake, based on the distribution of aftershocks and other seismic information from the U.S. Geological Survey.A new image based on the model shows what the earthquake may look like through the eyes of an interferometric synthetic aperture radar, such as NASA's Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR). JPL scientists plan to acquire UAVSAR data from the region of the March 28 quake, possibly as soon as this week, and process the data to validate and improve the results of their model. The UAVSAR flights serve as a baseline for pre-earthquake activity. As earthquakes occur during the course of this project, the team is measuring the deformation at the time of the earthquakes to determine the distribution of slip on the faults, and then monitoring longer-term motions after the earthquakes to learn more about fault zone properties.
