A US man has been arrested for allegedly knocking over a security robot while drunk. The incident took place in a car park in Mountain View, California. The autonomous robot, called K5, suffered a number of scratches but is now back on patrol.
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.
