The drone is a system, controlled by the RC remote, this transmitter sends wireless commands to the receiver, by pressing another button of the remote and the receiver will start the camera and stream the live video on the screen wirelessly. The aim of the study is to design and construct an Anti-Riot Drone with Tear Gas. In achieving this aim, the following specific objectives were laid out to design a drone with tear gas carrier and construct a tear gas dispensable drone with a remote controller. The motivation of embarking on this project is that, riot people violently throw stones and set buses on fire. To control such situations police and armed force is appointed. They have used lathis or batons, water cannons and teargas to disperse an unlawful assembly. Tear gas is sometimes difficult for policemen to execute, it can’t be thrown from long distance or it becomes difficult to go between the aggressive crowd throwing stones, to overcome such problem this Anti- Riot Drone will help armed forces to control riot crowd. The other joystick is used for altitude control, it controls how high the drone flies. Using a button, the remote we control the dropping of the tear canister. In this system, the drone will have an assembly to carry the tear gas canister. This study will be of immense benefit to Military force, Police other researchers who intend to know more on this study and can also be used by non-researchers to build more on their research work. This study contributes to knowledge and could serve as a guide for other study.
