The same day that Amazon announced a trial run of its delivery by drone service in India, a couple of MIT researchers released a new study that shows how to keep delivery drones running efficiently — and it’s funded by Boeing. A team of researchers have developed what is essentially a health kit for drones, to help avoid in-flight failures and breakdowns. The first algorithm allows an in-flight drone to monitor fuel level and the condition of parts like propellers and cameras, and to make proactive decisions. If the fuel level is low, for example, a drone with MIT’s algorithms can anticipate the need for fuel and go to a station.
