Claw inspired by sea urchins' mouth can scoop up Martian soil
A sea urchin's mouth looks pretty terrifying, but the teeth inside can demolish even the toughest rocks. That's why the nightmare fuel inspired a group of UC San Diego researchers to create a claw-like device that can scoop up soil on extraterrestrial environments. The group of engineers and marine biologists 3D-scanned the mouth of a Strongylocentrotus fragilis, which is more commonly known as pink urchin, for the project. To copy the animal's mouth, they arranged the device's teeth in a dome-like formation. They open outwards and close in, just like one of those claw games in the arcade.
