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.
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.”
October 10, 2012 — A Georgia Tech research team has received a grant to develop a robot capable of using objects in its environment to accomplish high-level tasks. The team recently received a three-year, $900,000 grant from the Office of Naval Research to work on this project.
Sept. 25, 2012 — Using a novel method of integrating video technology and familiar control devices, a research team from the Georgia Institute of Technology is developing a technique to simplify remote control of robotic devices. The researchers’ aim is to enhance a human operator’s ability to perform precise tasks using a multi-jointed robotic device such as an articulated mechanical arm.
August 6, 2012 — Using computational modeling techniques, researchers have designed micro-swimmers that could overcome the challenges of swimming at the micron scale. These autonomous micro-robots could carry cargo and navigate in response to stimuli such as light.
July 5, 2012 — Using piezoelectric materials, researchers have replicated the muscle motion of the human eye to control camera systems in a way designed to improve the operation of robots. This new muscle-like action could help make robotic tools safer and more effective for MRI-guided surgery and robotic rehabilitation.
