Drones play a major role in the fields of surveillance, package delivering, weather
forecasting, power delivering, wild-life mapping, and many other tasks also. ’Scope of the
mission’ and the ’Battery power’ plays an important role while using these drones. It is that
these both issues will be caused to vary the ’Flight time’ of the drone. Instead of using human
interaction for the battery change, battery charging techniques were implemented. To
bypass the inconvenience that happens in the battery changing process, automated battery
swapping systems were implemented. This research presents a novel concept for a battery
swapping system that uses the ‘Ceiling effect’ of the quad copter, which will stick the drone
to the ceiling and swap the battery under the ceiling. The proposed ceiling-swap method allows
the carry-under load of the delivery drone to remain attached throughout the servicing
period. Finite Element Analysis (FEA) and a kinematic calculation were done as a simulation
and the prototype was demonstrated for experiments. ’DJI TELLO’ small scale quad
rotor drone was applied to do the research work and to demonstrate the proposed research
for future directions. Finally, the advantages, limitations and the future directions of the
research have been discussed.
