When building this drone, there was a point where the wiring was not done correctly, and was reversed which resulted in a short circuit and the ignition of the esc and the motor itself. As the wiring was wrongly done (the poles of the battery connected incorrectly to the electronic speed controller (esc), this resulted in the motor burning out and being unable to spin. Aside from that, the rotors that I used was also bought in only one configuration. As the rotors were provided only in one angle (slanted down on the right, and less on the left), new rotors of different configurations had to be purchased, as the usage of all 4 identical motors would result in the spinning motion of the drone as it is elevated from the ground.

The Features of This project's Drone

- Wireless connectivity until 100m radius- this is better than most drones that implement wi-fi connectivity, excluding ones that top the market (implementing radio control). 

- High maximum load – the four proppellers of each rotor are able to produce large amounts of upward thrust needed to lift the drone and its package up in the air. 

- High battery life- the battery used supplies high power (voltage) to the propellers for long periods of time. Typically, drones make use of smaller Lithium ion batteries, however, these do not inject enough power or are often very short lasting.

Project's Limitations 

One of the most prominent llimitation to this project would be the range of the drone. As a delivery drone, it would be required for the drone to have a large radius of connectivity, in order to reach further areas with ease.

Some ways to addressed the limitations

In order to address the problem of the lack of range for the drone. The implementation of a radio controlled frequency can be added to the drone, instead of it being controlled by WI-Fi. As Wi-Fi limits the range of connectivity due to the nature of the connection being dependent of the signals sent and received between the source (the device) and the drone, the usage of radio waves can be able to significantly enhance the flight range of the drone. As radio waves emit wavelengths that can be transferred over long distances, it can be predicted that the implementation of radio waves might and can increase the flight distance of the drone for up to 2-3 kilometers. However, a challenge that might arise from this is to find the right frequency for the radio wave itself. Avoiding the other radio frequencies emitted from other sources, the disruption of the radio wave signal may be dangerous for the drone (causing it to lose contact or in some cases, fall and plummet to the ground). Therefore, finding the right frequency and calibrating it well with the drone is a tedious, long but very important process which may improve the usability of my Unmanned Aerial Vehicle.
