Introduction
Transportation is a crucial aspect of modern-day life, enabling people and package to move from one place to another with ease. However, in rural areas, the lack of sufficient transport infrastructure can lead to significant challenges for the local community. The absence of reliable and affordable transportation options can limit access to healthcare, education, and economic opportunities, thereby hindering the growth and development of these regions. In recent years, quadcopters have emerged as a promising solution to this problem. With their ability to navigate difficult terrain and fly over obstacles, quadcopters can serve as a low- cost, modified transport system in villages, providing a faster and more structured means of transportation for people and goods alike. Furthermore, quadcopters are highly versatile. For instance, they can be designed to transport medical supplies, food, and other essentials to remote areas that are difficult to access by road [1].
Another advantage of quadcopters is their low cost. Quadcopters, on the other hand, are relatively inexpensive to operate and maintain, making them a viable option for low- income communities [2]. Moreover, their small size and portability make them easy to transport and deploy in a variety of settings, further adding to their appeal as a low-cost transport solution. Quadcopters represent a unique opportunity to create a low-cost modified transport system in villages.
By harnessing the power of this advance technology, we can transform the way transportation is viewed in rural areas, enabling people to access the resources and services they need to thrive. With their versatility, affordability, and
adaptability [3], quadcopters have the potential to revolutionize rural transportation and bring about positive changes for millions of people on every side of the world.

Fig. 1. Block Diagram of the proposed system
Fig. 1 shows in a quadcopter for a low-cost modified transport system in villages, signals are transmitted from a transmitter to the receiver on the drone. The receiver then processes the signal using an accelerometer and gyroscope sensors, which sends it to the flight controller. The flight controller processes the signal and sends it to the electronic speed controllers (ESCs), which regulate the amount of current sent to the motors. The motors, in turn, rotate the propellers, producing thrust and allowing the quadcopter to take off and fly.
A quadcopter, also known as a quadrotor, is a type of unmanned aerial vehicle (UAV) that is propelled and controlled by four rotors. It operates based on the principles of aerodynamics and the manipulation of the thrust and torque generated by the rotors. Here's a general overview of how a quadcopter works:
Frame and Structure: A quadcopter consists of a rigid frame that houses all the necessary components. The frame provides structural support and holds the motors, propellers, electronic control systems, and other components in place.
Motors and Propellers: The quadcopter has four motors, each connected to a propeller. The motors generate rotational force or torque, which is transferred to the propellers, causing them to spin. Two propellers spin clockwise, while the other two spin counterclockwise.
Flight Controller: The flight controller is the brain of the quadcopter. It receives input from various sensors, such as accelerometers, gyroscopes, and barometers, which provide information about the quadcopter's orientation, position, and altitude. The flight controller processes this data and sends commands to the motors to adjust the thrust and maintain stability.
Flight Modes and Control: The quadcopter can operate in different flight modes, such as manual mode (piloted by a remote controller) or autonomous mode (controlled by pre- programmed instructions or sensors). The pilot or autonomous system adjusts the throttle of each motor to control the lift and maneuverability of the quadcopter.
Stability and Maneuverability: The quadcopter achieves stability and maneuverability through the differential control of the four motors. By varying the rotational speed of the motors, the flight controller can adjust the thrust generated by each propeller, allowing the quadcopter to move in different directions, change altitude, or rotate around its axis [12].
Control Inputs: In manual mode, the pilot provides control inputs through a transmitter or remote controller. These inputs, such as throttle, pitch, roll, and yaw, are translated into commands by the flight controller to adjust the motor speeds and achieve the desired movement of the quadcopter.
Power Source: The quadcopter is powered by a battery or a similar power source, providing electrical energy to the motors, flight controller, and other onboard systems. The battery capacity determines the flight time and endurance of the quadcopter.
By dynamically adjusting the motor speeds based on control inputs and sensor feedback, a quadcopter can achieve stable flight, perform maneuvers, and respond to changes in its environment. The combination of thrust differentials and precise control allows the quadcopter to hover, fly forward or backward, turn, and perform other flight maneuvers.

RESULTS & DISCUSSIONS
Drone delivery systems are becoming increasingly popular as an alternative means of delivering packages to customers. These systems typically involve the use of drones equipped
with servo motors to deploy the package once it reaches the delivery location. The servo motors are used to open a hatch on the drone's underside, allowing the package to drop safely to the ground below. The working system of a drone delivery system involves several steps. First, the package is loaded onto the drone and secured in place. The drone is then programmed with the delivery location and takes off, flying autonomously to the destination. Once the drone reaches the delivery location, it hovers in place while the servo motors activate, opening the hatch to release the package[15].
