“The APRICOT project has now developed a new robot that automates the process by using x-ray technology to locate the pin-bones in the fish and then quickly and precisely trim them away using water-jets.”
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.
