August 7, 2014 -- In one of the first autonomous demonstrations, the Georgia Tech Research Institute (GTRI) has successfully commanded three fully autonomous, collaborating UAVs. The machines flew in close formation at the same altitude, separated by approximately 50 meters as they executed figure-eight patterns.
March 26, 2014 - A new robotic system at Georgia Tech’s Center for Chemical Evolution could soon let scientists better simulate and analyze the chemical reactions of early Earth on the surface of real rocks to further test the theory that catalytic minerals on a meteorite’s surface could have jump-started life’s first chemical reactions.
October 10, 2013 - A new study suggests that ‘unpredictable climate variability’ behaves in a more predictable way than previously assumed.
June 18, 2013 -- Antenna technology originally developed to quickly send and receive information through a software-defined military radio may soon be used to transmit ocean data from a wave-powered autonomous surface vehicle. The technology, the lowest-power method for maintaining a satellite uplink, automatically compensates for the movement of the antenna as the boat bobs around on the ocean surface.
June 4, 2013 -- A new study shows that similar timing patterns are used by many swimming animals to produce undulatory swimming motions. Scientists have created a simple model of these patterns and applied it to understand the connection between electrical signals and body movement in the sandfish, a lizard.
May 20, 2013 -- Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
April 26, 2013 -- Using bundles of vertical zinc oxide nanowires, researchers have fabricated arrays of piezotronic transistors capable of converting mechanical motion directly into electronic controlling signals. The arrays could help give robots a more adaptive sense of touch, provide better security in handwritten signatures and offer new ways for humans to interact with electronic devices.
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.
March 21, 2013 -- Using a combination of theory and experiment, researchers have developed a new approach for understanding and predicting how small legged robots – and potentially also animals – move on and interact with complex granular materials such as sand.
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.
