DJI Promises to Add “AirSense” to Its New Drones

The company plans to include ADS-B receivers in next year’s drones weighing more than 250 grams There’s been a lot of talk over the years about endowing drones with the ability to “sense and avoid” nearby aircraft—adding radar or optical sensors that would mimic what a pilot does when she peers out the window in all directions to be sure there are no other aircraft nearby on a collision course. But incorporating such sense-and-avoid capability is quite challenging technically, and would probably never be possible to add to small consumer drones. Thankfully, the threat of mid-air collision can be reduced using a strategy that is much easier to implement: Have aircraft track their positions with GPS and then broadcast that information to one another, so that everybody knows where everybody else is flying. Drones could at least receive those broadcasts and alert their operators or automatically adjust their flying to steer Continue reading DJI Promises to Add “AirSense” to Its New Drones

Big energy savings for tiny machines

Physicists demonstrate for the first time a strategy for manipulating the trillions of tiny molecular nanomachines inside us that work to keep us alive, to maximize efficiency and conserve energy. The breakthrough could impact numerous fields, including creating more efficient computer chips and solar cells for energy generation. More details
