Specification

Description:The Present invention works by ensuring enhanced security measures, enhance indoor monitoring, threat identification, and situational awareness at proper location through a Wi-Fi network, which have internet access. The nano drone operates with an electrical power source which provides power to the Brushless Direct Current motors, Flight control board along with the electronic speed controllers. The supplied power from the battery is utilized by all the other components to coordinate and make the drone operate in its best efficiency. The indigenously designed drone body is manufactured using additive manufacturing technology, leveraging the benefits of 3D printing. PLA filament, a popular material for 3D printing, is utilized to create the body and arms of the drone. This thermoplastic material offers good strength and rigidity while remaining lightweight, making it ideal for drone construction.
[0016] The BLDC (Brushless Direct Current) motors are widely used in the drone industry. In BLDC motors, the Kv rating gives details about the RPM of the motor per supplied voltage. For example, a 1000Kv motor, if powered with a 3S battery (11.1 V), will spin up to 1000Kv*11.1V = 11000 RPM at no load condition. From the consideration of the maximum take-off weight, a motor that can give around 125g of thrust is required. Emax ECO 1106 is a 4500Kv BLDC motor that runs on 2S- 3S batteries and the motor is depicted in Figure 7. It requires a 3" propeller to give 135g of thrust. It consumes about 4.2 A of maximum current.
[0017] For the flight controllers, the power module provide a regulated 5v supply, even though the output voltage of the battery is higher, it steps down the incoming voltage to power the flight controller. The flight controller has an inbuilt microprocessor, which processes the input provided by the pilot using their controller/transmitter. They receive the input with the help of a receiver present in the composition of the drone, and then it processes the information and sends out commands to the Electronic Speed Controller (ESC).These ESCs receive these commands and sends out signals to the actuators which are the motors connected along with the propellers.
[0018] To reduce the drone's weight, a 4-in-1 stack ESC was picked in place of 4 separate ESCs and it is depicted in Figure 8. This ESC can withstand up to 25A of nominal current and 30A of burst current. It weighs 5g.
[0019] For each maneuver the signal from the ESCs to the motor varies to make the motors rotate in different RPMs to perform a certain maneuver. There are also some external components connected with the Flight controller such as camera and GPS. The camera is used for First person view if required and for its main objective of monitoring and surveillance.
[0020] To ensure smooth and precise flight control, the drone is equipped with a Pixhawk mini- Flight Controller Board (FCB). Flight controller boards are the brain of unmanned aerial systems. They sent commands to control the action of other components in a drone. In different flight controllers available in market, Mini pix is used with ARM cortex micro- controller. The circuit has vibration damping and seals from external air vent thus providing better results from barometer and inertial measurement unit (IMU) to have a better control.
[0021] This advanced controller board provides efficient and reliable control over the drone's flight dynamics, ensuring stability and responsiveness during operation. Powering the drone are four Emax 6000KV BLDC (Brushless Direct Current) motors. These high performance motors, combined with suitable Electronic Speed Controllers (ESCs) and 2-inch propellers, deliver approximately 100g of thrust per arm. This propulsion system enables the drone to achieve optimal lift and maneuverability, facilitating agile flight in indoor environments.
