To understand their strategies for working effectively without clogging traffic jams, researchers studied how fire ants dug tunnels in glass particles that simulated soil. (Credit: Rob Felt, Georgia Tech)
A new study shows that ants have a lot to teach robots about working in confined spaces.
Researchers studied the motion of mudskippers to understand how early terrestrial animals might have moved about on mud and sand, including sandy slopes. This animal was photographed at the Georgia Aquarium in Atlanta.  (Credit: Rob Felt, Georgia Tech)
A new study used a robot to help understand how the first land animals moved about.
