A professor at Stanford University has designed a robotic humanoid diver with articulated hands that is designed to be an underwater avatar, exploring the way a human would— while its driver remains safely up at the surface.
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.
