“Researchers from Mexico’s University of Guadalajara (UDG) have developed an algorithm that could come in handy in such situations by allowing robots to differentiate between people and debris.”
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.
