Meshworm: The biomorphic soft robot

The last few years have seen the rise of “soft robots,” squirming, biomorphic, and highly flexible little machines that can be used to slip through cracks, infiltrate tight spaces, even explore architectural ruins in the wake of earthquakes and warfare.

The so-called “meshworm” is exactly that: a robotic “worm” made from layered wire mesh that uses “nickel-titanium alloy for muscles.” The application of a high temperature “shortens the wire, tightens the spring’s coil, and squeezes that body segment.” Thus, “when a segment contracts, the one behind it stretches out, and the robot inches forward. The tendon also has muscles attached so the robot can turn left or right.”
