Octopus‑inspired Rescue Robots

A Journal of Experimental Biology experiment documents a stepwise, anchor‑and‑lever strategy octopuses use to pull their soft bodies and head capsule through holes, and it shows species differences in willingness to attempt very small gaps. Translating those concrete maneuvers (arm probing, sequential arm passage, head‑first jimmies) could guide the design of soft search‑and‑rescue robots able to traverse collapsed buildings and other confined disaster environments. — If engineered into deployed robots, these biologically derived mobility techniques could change capabilities and procurement priorities for disaster response, urban search‑and‑rescue, and civil‑defense planning.
