This is PATRICK: Meet the brittle star-inspired robot that can crawl underwater

Researchers at Carnegie Mellon University have recently created PATRICK, an untethered soft robot that artificially replicates the structure and behavior of the brittle star, a marine invertebrate closely related to starfish. This unique bio-inspired robot, presented in a paper pre-published on arXiv, can crawl underwater using five legs actuated by shape-memory alloy (SMA) wires.
