From the LASA Lab at EPFL: The LASA robots secretly team up with Santa to organize the Christmas gifts! Happy Holidays from the Learning Algorithms and Systems Lab!
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.
