This manta ray-inspired soft robot flies through the water

Biologically inspired soft robots make a lot of sense in a lot of different scenarios, but as with any class of technology, they have their limitations. Among other things, these compliant structures can struggle to move at the same speed as their more rigid counterparts. To help speed up swimming, a team of researchers at North Carolina State University turned to another bit inspiration from nature: the manta ray.
Looking toward the fish makes sense. These cousins of sharks effectively fly through water courtesy massive, wing-like pectoral fins. Ultimately, however, the researchers named them
