FlipperBot: Sea Turtles and Flipper-Driven Robot Reveal Principles of Moving on Sand and Other Granular Media

April 23, 2013 — Based on a study of both hatchling sea turtles and “FlipperBot” — a robot with flippers — Georgia Tech researchers have learned principles for how both robots and turtles move on granular surfaces such as sand.

Anatomy of a Blast: Researchers Develop Sensor System to Assess the Effects of Explosions on Soldiers

April 23, 2013 — To study the effects of improvised explosive devices on soldiers and help provide continuing treatment, researchers have developed a sensor system that measures the physical environment of an explosion and collects data that can correlate what the soldier experienced with long-term outcomes.

Drone Defense: Helping Protect U.S. Forces by Simulating Hostile Unmanned Aircraft

April 10, 2013 — The Georgia Tech Research Institute (GTRI) is developing integrated hardware devices that simulate sensors potentially present on enemy unmanned aerial vehicles. The technology is expected to be used to gauge the effectiveness of U.S. countermeasures against enemy drones.

3-D Cooling: DARPA Funds Research to Improve Heat Dissipation in 3-D Microelectronic Systems

April 2, 2013 — Researchers from the Georgia Institute of Technology have won a Defense Advanced Research Projects Agency (DARPA) contract to develop three-dimensional chip-cooling technology able to handle heat loads as much as ten times greater than systems commonly used today.

Radar Advance: Acoustic Time Delay Device Could Reduce Size and Cost of Phased Array Systems

March 29, 2013 — Researchers have developed an ultra-compact passive true time delay device that could help reduce the size, complexity, power requirements and cost of phased array designs. The device uses the difference in speed between light and sound to create nanosecond signal delays.

Flying Test Bed: New Aerial Platform Supports Development of Lightweight Sensors for UAVs

January 16, 2013 — A research team at the Georgia Tech Research Institute (GTRI) is developing an airborne testing capability for sensors, communications devices and other airborne payloads. This aerial test bed, called the GTRI Airborne Unmanned Sensor System (GAUSS), is based on an unmanned aerial vehicle (UAV) made by Griffon Aerospace and modified by GTRI.

Monitoring Hurricanes: Georgia Tech Engineers Assist NASA with Instrument for Remotely Measuring Storm Intensity

December 13, 2012 — A device designed by engineers at the Georgia Tech Research Institute (GTRI) is part of the Hurricane Imaging Radiometer (HIRAD), an experimental airborne system developed by the Earth Science Office at the NASA Marshall Space Flight Center in Alabama.

Stutter Jumping: Study of 20,000 Jumps Shows How a Hopping Robot Could Conserve its Energy

October 26, 2012 — A new study shows that jumping can be much more complicated than it might seem. In research that could extend the range of future rescue and exploration robots, scientists have found that hopping robots could dramatically reduce their power demands by adopting a unique two-part “stutter jump.”

Radar Renewal: Phased Array Technology Could Improve Reliability, Capabilities of Air Traffic Control System

August 2, 2012 — A research team from the Georgia Tech Research Institute (GTRI) is working with the Federal Aviation Administration (FAA) and National Oceanic and Atmospheric Administration (NOAA) to investigate alternative approaches to the radars that currently support the nation’s air traffic control and weather monitoring systems.

Picture Worth a Thousand Numbers: New Data Visualization Tool Helps Find the “Unknown Unknowns”

July 26, 2012 — A research team at the Georgia Tech Research Institute (GTRI) has developed a software tool that enables users to perform in-depth analysis of modeling and simulation data, then visualize the results onscreen. The new data analysis and visualization tool offers improved ease of use compared to similar tools, the researchers say.
