Earthworms move by contracting body segments in a wave-like motion, which is ideal for tight spaces. Interestingly, this robotic version could be used to install power lines underground efficiently.

An earthworm-inspired, self-propelled robotic sleeve designed for installing underground power lines has been developed by a ...

A worm is a long, creeping animal, with a soft, often segmented body. They don't have legs but instead are covered in hairs or bristles that help them to move. They breathe through their skin ...
