A drone, in simple words, is a type of flying robot that can be remotely controlled by a human operator. It is in technology terms also known as Unmanned Aerial Vehicle (UAV). With many new advancements in drone technology, it is expected that drones may expand further to include diagnostic capabilities, namely in the imaging field. The drone presented in this paper will also be used for the delivery of medical supplies. With a lock system implemented on the container attached, it ensures the safety of the supplies till they reach the rightful person. The drone could be used by online pharmaceuticals, which are booming as people are gaining interest in them. The designed system is an internet-based drone using the principles of IoT.
