University of Colorado Assistant Professor Nikolaus Correll, speaking at TEDx Front Range earlier this year, outlined his vision for transforming agriculture through robotic cultivation.
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.
