Researchers have developed a control mechanism that allows a snake-shaped robot to safely navigate through an unfamiliar environment.

A number of different research groups are developing robots that mimic real snakes: their shape and simplicity make them ideal for crawling through pipes or exploring narrow or cluttered environments.

And yet, while most of these robots can crawl along and turn on command, getting them to navigate independently has so far proven difficult. Their mode of locomotion means their body is continually changing shape and position.
