What do swimmers like trout, eels and sandfish lizards have in common? According to a new study, the similar timing patterns that these animals use to contract their muscles and produce undulatory swimming motions can be explained using a simple model.
A trio of American scientists has developed a sea turtle-like robot dubbed 'Flipperbot' to help them learn about the mechanics behind walking on sand-like surfaces.
"Terradynamics" could be the next big thing in robotics, helping vehicles move on granular and other complex surfaces like beaches.
The sandfish's slithering moves are inspiring new robotic moves that could one day help search-and-rescue crews find survivors in piles of rubble left from disasters like Hurricane Katrina.
Researchers at the Georgia Institute of Technology recently built a robot that can penetrate and "swim" through granular material.
Life can be scary for endangered loggerhead sea turtles immediately after they hatch.
A study published in the July 17 issue of the journal Science details how sandfish -- small lizards with smooth scales -- move rapidly underground through desert sand.
Today's advanced mobile robots explore complex terrains across the globe and even on Mars, but have difficulty traversing sand and other granular media like dirt, rubble or slippery piles of leaves.
