A team of students from Oakton Community College earned second place in a NASA robotics mining competition last month beating out teams from other universities and colleges with significantly more resources to devote to the project.
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.
