A starfish-shaped soft robot that creeps, changes its color, and self-heals broken parts

Natural camouflage is one of nature's most interesting traits. Materials scientists have now developed a material that can mimic the camouflage capabilities of marine mollusks. They created a starfish-shaped soft robot that responds to heat and pressure with deformation, movement, and color changes. Cut-off tentacles can be welded together, and the material can be fully recycled, they write in the journal Angewandte Chemie.
