The laser-guided ‘Geta’ (get a car) robot slides under your vehicle to pick it up. It then finds a parking space in the lot and places the car in the tightest of spots.
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.
