Mesh Robot Crawls Like an Earthworm

Researchers at MIT, Harvard, and Seoul National University have created a soft autonomous robot that moves via peristalsis, crawling across surfaces by contracting segments of its body, much like an earthworm. The robot has been dubbed 'Meshworm' for the flexible, mesh-like tube that makes up its body. 'Artificial muscle' was created from wire made of nickel and titanium - a shape-memory alloy that stretches and contracts with heat. Meshworm is remarkably resilient and may be useful for navigating rough terrain or squeezing through tight spaces.
