Feather star-inspired underwater robot gets 3D maneuverability from only two actuators

What happened

Researchers have created an aquatic soft robot inspired by marine invertebrates called feather stars. The feather star robot is able to move through the water in all three dimensions, powered by only two actuators (the part of a machine that produces movement). The paper, "Minimal-Actuation Feather Star–Inspired Soft Swimmers for Multimodal 3D Maneuverability," is published in the journal Science Advances.
