We have seen a few different takes on this same problem, all aimed at minimizing the human role in autonomous drone flight. The SkySense device we covered back in 2014 was essentially a landing pad that doubled as a wireless charging station, but given the time it takes to recharge a drone (let alone without wires), it couldn't really lay claim to providing continuous flight. The Dronebox from earlier this year offers a little more shelter for long term drone deployment, but it too lacked the ability to get the drone back into action without delay.
