QUADO: An autonomous recharge system for quadcopter

Tn this paper we present a new design of an autorecharge drone system consist of drones auto-landing program and recharging ground stations, working with battery swapping and charging structure. Recently the application of drones expanded fast, drones for aerial photography or other entertainment use are no longer the only thing micro drones can do. Companies like Amazon are starting to consider the use of drones in their day-to-day business, also the Chinese ministry of electric power already have some special built quadcopter-drone to do wire inspection work. As micro drones will have more and more use-cases, the limited battery life becomes the main restriction on their using in long-time-flying missions. We argue that this problem can be solved in other ways than mere brute force. With camera and infrared (IR) sensor, drones in this system can landing accurately on the station to replace the battery. This system is a prototype system, includes the design of the battery swapping mechanisms and the landing control system with test results.
