Engineers have created a robot that mimics a worm’s movements – crawling along surfaces by contracting segments of its body.
The technique allows the machine to be made of soft materials so it can squeeze through tight spaces and mould its shape to rough terrain.
It can also absorb heavy blows without sustaining damage.
The Pentagon’s Darpa research unit supported the Meshworm project, suggesting a potential military use.
Work on the machine was carried out by researchers at the Massachusetts Institute of Technology and Harvard University in the US, and Seoul National University in South Korea.
