Learning from Ants: Principles of Locomotion in Confined Spaces Could Help Future Robot Teams Work Underground

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.

Artificial Transparent Skin: Arrays of Piezoelectric “Taxels” Convert Mechanical Motion to Electronic Controlling Signals for Improved Tactile Imaging

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.

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.

Terradynamics: New Technique Could Help Designers Predict How Legged Robots Will Move on Granular Media Like 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.

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.

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.”

Robots Using Tools: With New Grant, Researchers Aim to Create ‘MacGyver’ Robot

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.

Easy Guider: Intuitive Visual Control Provides Faster Remote Operation of Robots

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.

Microswimmers: Research Shows Micron-Scale Swimming Robots Could Deliver Drugs & Carry Cargo Using Simple Motion

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.

Robot Vision: Muscle-Like Action Allows Camera to Mimic Human Eye Movement

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.
