Field of Invention
Drones offer a multitude of advantages in the twenty-first century, which is why they are becoming more popular among the general public. Drones can be classified as quadcopter, hexacopter, or octacopter depending on the number of propellers employed. A quadcopter suited for cargo transportation will be planned in this invention. A quadcopter is a one-of-a-kind Unmanned Aerial Vehicle (UAV) with vertical take-off and landing capabilities. Drones may weigh anything from 500grms to 1kg, depending on how many motors are utilised, whereas quadcopters can weigh up to 500grms. The quadcopter is developed in this innovation, and it is operated remotely from a ground control station using RASPBERRY PI, with GPS being utilised to track the quadcopter. Individuals may focus solely on request fulfilment by incorporating automation into our design, and another benefit is that the package will arrive in good condition. Drone delivery will reduce both time and energy use. Unmanned aerial vehicles (UAVs), commonly known as drones, might potentially reduce the cost and time required to transport packages in delivery applications. Automatons are less expensive than transportation vehicles.

Background of Invention
Drones can also save money on manpower. Automated conveyance may prove to be both faster and less costly. During a crisis, transportation to any location becomes conceivable. Through software-controlled flying pans in its embedded systems, it may be remotely commanded or fly autonomously. UAVs have recently been employed in the military to acquire data. Drones are also employed in a variety of civilian applications, including drone traffic monitoring, personal drones, and business. Unmanned aerial vehicles (UAVs) have the potential to be used in a wide range of commercial applications, some of which may require lengthy missions. As a result, it's critical to develop UAVs that can accomplish missions efficiently while also conserving energy. A UAV must undertake a number of maneuvers/movements to complete a defined flight mission, each of which consumes a specific amount of power. To optimise cruising duration, not only must the power source be capable of providing adequate power to the UAV, but also must the UAVs components work effectively in order to preserve power. The power consumptions of the UAV parts for the desired mission must be properly examined before the minimal power capacity can be calculated.

Summary of the Invention
Late delivery of medications has resulted in some unexpected fatalities throughout the world.
The manual system is experiencing traffic issues. As a result, in this study, a drone-based delivery system is devised and constructed. There are two primary components in this system. The server and the quadcopter it is the ground control station that wirelessly controls the quadcopter. The developed device can carry up to 500 grammes and travel at 31 metres per second, with a range of 120 metres depending on the battery. Drones may be monitored using a camera array for large-scale air space surveillance. A modular camera array system with aural assistance was suggested in this research. In various directions, the System gathers picture and audio information of the surroundings. The system may combine data from several sources.
A collection of sensors is attached to the flight controller. These sensors provide information to the flight controller regarding the aircraft's height, orientation, and speed. An inertial measurement unit (IMU) is used to determine angular speed and acceleration, a barometer is used to determine height, and distance sensors are used to identify obstructions. The drone filters a lot of this information and combines some to acquire more efficient and accurate information, just as we do as people. Advanced flight controls can identify discrepancies more precisely and faster.
A secure UAV-assisted heterogeneous network environment is provided, as well as a seamless IP prototype. To overcome a long-range communication barrier and improve remote sensing, the UAV is operated over the Internet. Without knowing anything about network designs, network address translation kinds, or Internet protocol version, a pilot can operate a UAV via end device (ED)-secured communication. Network traversal with mobility (NT Mobile) allows UAVs to communicate in a secure manner over a public network infrastructure. By generating keys and creating tunnels utilising virtual IPs for two nodes within the network, NT Mobile improves security and maintains mobility. The UAV flight controller can install a ground control station application on the UAV board in the prototype. Different types of UAVs are available in the market, including a gasoline-powered heavyweight having an average flight time of almost four hours, small units having a flight time of less than an hour, and a basic autopilot control system. The history of UAV started in the early 1960s when it was used by the Air Force as a weapon system

Detailed Description of the Invention
In this invention there are two processes that are running in this invention, (i) The Complete
Process (ii) The Receiver Unit. In the fist process when the power supply is connected to the controller it starts functioning. The controller is Pixhawk flight controller that is used in this invention. This is attached to the RC Transmitter. On one side there is chip for the GPS Module that is attached to this controller. The Tilt sensor is available for vehicle movement. Then the first servo motor is used for Frame with propeller for flight controlling and the second servo motor is used for 4 wheeler control for car prototype. The output is used in the second process that is the receiver unit.
A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work. It's a circuit board with a range of sensors that detect movement of the drone, as well as user commands so Pixhawk 2.4.8 does. Using this data, it then controls the speed of the motors to make the craft move as instructed.
It Supports 8 RC channel with 4 serial port. Various user interfaces are available for programing, reviewing logs, even some apps for smartphones & tablets. It detects and configures all its peripherals automatically
The benefits of the Pixhawk system include a Unix/Linux-like programming environment, completely new autopilot functions that are used for sophisticated scripting of missions and flight behaviour, and a custom PX4 driver layer ensuring tight timing across all processes. A Quadcopter is essentially a flying device with 4 electric motors and propellers to power it. These devices are perfect for surveillance and filming applications and come in a number of sizes according to your need. The four rotors are used to generate the uplifting thrust which carries this device. The weight is divided among the four rotors. The Quadcopter is also controlled by using these motors by changing the amount of power each motor is producing. The frame should be strong and flexible to accommodate vibrations produced. It should have a center holding plate for mounting the electronics, four arms, and four motor brackets to connect each motor to each arm end.
The material used can be aluminum, carbon fiber or wood. Aluminum is mostly used since it is light, rigid and cheap. But they do not accommodate vibrations as well as carbon fibers. These motors are identical to traditional DC motors, however; they do not have any brushes. Make sure to check the RPMs (revolution per minutes) the motors can generate through the

'Kv-rating' (RPM constant of a motor). As mentioned before the motors should rotate anti-clockwise to counteract the torque of the propeller. Propellers will generate the necessary thrust for your Quadcopter. Make sure to buy the corresponding clockwise and anticlockwise rotating pairs of propellers. You will have to choose the pitch and diameter according to the thrust required and the required application of your Quadcopter.
You can program and control your Quadcopter by an RC transmitter. You can choose two modes, Acrobatic or Stable. As a beginner you should stick to Stable mode, the motor speeds will be controlled automatically and the drone will remain balanced. In an Acrobatic mode, the gyroscope is the only one processing values. The controlling sticks will help you control the quad and it is not re-balanced automatically. This mode is useful while performing aerial stunts, but is difficult to control. Some RC control systems include Futaba, Spektrum, Turnigy, and FlySky.

Different Embodiment of Invention
i. We offered the automaton conveyance difficulties (DDPs: Delivered Duty Paid) that
limit cost or conveyance time while taking into account battery weight, payload
weight, and automaton reuse, and we actualized them as blended number straight
projects based on this estimate. ii. We developed a string-based recreated tempering computation for fathoming the
DDPs to address relevant circumstances with many regions. iii. For flight testing, an Octarotor UAV was created utilising carbon strand/epoxy
composite material. A method for estimating the UAV's power consumption has been
proposed. iv. The power consumptions of the UAV's critical components were estimated using
appropriate equations and testing procedures. The entire energy consumption of the
UAV has been predicted using the power consumption of the critical elements for
various flight missions. v. The energy consumption of the UAV was measured throughout two flight tests. The
accuracy and practicality of the suggested energy consumption estimation approach
were confirmed by the testing findings.
