A small team at NASA’s Ames Research Center has set out to “boldly grow where no man has grown before” – and they’re doing it with the help of thousands of children, a robot, and a few specially customized GoPro cameras.

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.
