Researchers from a variety of universities have just announced that they’ve taken a different approach to make a soft robot. To create their robotic ray, they engineered some pretty special heart cells and attached them to a golden skeleton.
Robots clean rivers and sort waste, monitor ecosystems, and inspect renewable-energy infrastructure. But even the greenest robot has an environmental footprint.
EPFL engineers have designed acoustic cavities that convert sound waves into thrust, propelling small robots and ultralight aerial vehicles without on-board actuators or electronics.
