The 2015 technical roadmap from NASA is a sprawling series of documents designed to support the space agency’s missions—including a trip to Mars—as well as develop new technologies to make computers that can withstand radiation.
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.
