So this is an autonomous drone which can move in a specified path. It can be powered by solar energy and for extra power there will be charging pods present on the street lights. There will be cluster of these drones which can roam in entire city and do a full fledged surveillance. Now coming to the purpose of this drone. The main reason of increasing crime rates is that police is not able to arrive at right place at right time. Now these drone that are continuously monitoring, if they detect any person's help cry, they can send this signal to the nearest police station and can give the live recording along with the location to the police . Thus they will be easily able to monitor the mishap and can easily identify the criminal. Also, accordingly they can take action like making announcements or they can even make drones to shoot tasers to immobilize the criminal. These drones can also be used to catch criminals of hit and run cases, as they can easily tag the suspect's car.
For this purpose, we can use different materials, such as metal, plastic, or wood. These materials will differ based on how sturdy you intend the drone to be.
STEP 2: PROPELLERS, ELECTRONIC SPEED CONTROLLERS, AND MOTORS
They must be in accordance with the size of your drone. Multi-rotor drones produce greater speed and ensure a stable flight, as each rotor works with other’s thrust points. For better performance, it would be better to get carbon props.
STEP 3: ASSEMBLE THE MOTORS
The next thing we need to do is drill the holes in the frame for the motors, according to the distance between the screws holes on the motors.
