UAVs (Unmanned Aerial Vehicles), especially Quad copters is facing challenges in their mission due to its lower endurance. As such, the missions having long distances are not achievable through Quad copters. The performance of any vehicle, while testing, is one of the most important factors. This performance is based on range, endurance, altitude, attitude control, VTOL (Vertical Take-Off and Landing), battery life, and other autonomous functionalities. The major problem we are facing in the field of UAVs is battery life. The use of higher mAh battery is not a perfect solution as the weight also increases with the size of the battery and that will then require once level higher mAh battery and this may not end soon. Several different techniques can be applied to eliminate or reduce the above drawback. One can be, in the mission path itself, take the drone down to the ground, change its battery and continue the mission, which is a kind of out of logic things. The other solution which we can find is the use of a charging dock. In this case, no need to follow the vehicle, everything can be automatic with the help of a sensor and communication system. The above solution ends the endurance problem but, if the endurance is higher and mission is longer, it necessary to put on necessary sensors for the safety of the vehicle.
