A snake-like robot has been developed that can burrow through sand or loose soil.
Researchers at UC Santa Barbara (UCSB) & Georgia Institute of Technology have taken their cues from plants & animals that have evolved to navigate subterranean spaces.
They say they have "developed a fast, controllable soft robot that can burrow through sand.” The team is working on a project with NASA to develop Burrowing for the moon or even more distant bodies, like enceladus, a moon of Jupiter.
