Researchers at MIT, Harvard University and Seoul National University have developed a robotic worm that creeps along the ground, much like its real-life counterpart.
Engineers constructed the worm, using a soft mesh tube wrapped in nickel-titanium wire. After a small current is applied to the wire segments, they contract and squeeze the mesh tube, which then propels the ‘bot forward.
Made completely out of soft materials, the worm remains unscathed even when stepped on, or bludgeoned with a hammer.
