MIT scientists have invented an ingenious fixed-wing drone that can charge itself by simply sitting on a power line and using their emitted magnetic fields to recharge its batteries. This helps get around a common problem faced by most autonomous drones, which is that they can only fly for very short periods of time before they need to be charged up again.

Fixed-wing drones are actually not as good at perching on things as typical multi-rotor drones. However, the MIT team decided to go with a fixed-wing design anyway because these drones tend to be more fast and energy-efficient.

The perching capability of the drones was developed with inspiration drawn from birds and the manner in which they adjust the orientation of their body when preparing to perch.
