1) The document discusses the fabrication of a drone, or quadcopter, which uses four rotors - two rotating clockwise and two counter-clockwise - to provide lift and propulsion. Control is achieved by varying the RPM of the rotors using a microcontroller. 2) A quadcopter operates on the principle of aviation, with electronics and mechanics allowing the four motors to change speed and direction to move the device forward, backward, left, right, up, and down based on transmitted signals from a remote controller. 3) The group fabricated a basic quadcopter with a metal frame, 6V battery, range of 50 feet, and weight of 1kg to gain experience with soldering,

1. Synopsis
Title:- Fabrication of Drone.
Introduction:-
A Drone, also called a quadcopter, is a multirotor helicopter that is lifted and propelled
by four rotors. Most helicopters, quadcopters use two sets of identical fixed pitched propellers;
two clockwise (CW) and two counter-clockwise (CCW). These use variation of RPM to control
lift and torque. Control of vehicle motion is achieved by altering the rotation rate of one or more
rotor discs, thereby changing its torque load and thrust/lift characteristics by using a micro-
Controller. A number of manned designs of quadcopter appeared in the 1920s and 1930s.
Principle:-
Quadcopter is a device with a intense mixture of Electronics, Mechanical & mainly on
the principle of aviation. The Quadcopter has 4 motors whose speed of rotation & the direction
of rotation changes according to the users desire to move the device in a particular direction ( i.e.
Takeoff motion, Landing motion, Forward motion, Backward motion, Left motion, Right
motion.) The rotation of motion changes as per the transmitted signal send from the 6-Channel
transmitter. Each rotor produces both a thrust and torque about its center of rotation, as well as
a drag force opposite to the vehicle's direction of flight.
Basic Specifications:-
Metal :- Forex Or Aluminum ( Which is available )
Machine used for cutting frames :- CNC Or VMC Machines. ( which is suitable )
Battery :- 6 volts.
Flying Height :- 20 feets ( Approx.)
Weight :- 1 Kg. (Approx.)
Range Of Remote Controller :- 50 feets ( Approx.)
Controlling :- Microcontoller Chip

2. Advantages :-
(1)First, quadcopters do not require mechanical linkages to vary the rotor blade pitch angle
as they spin. This simplifies the design and maintenance of the vehicle.
(2)Second, the use of four rotors allows each individual rotor to have a smaller diameter
than the equivalent helicopter rotor, allowing them to possess less kinetic energy during
flight. This reduces the damage caused should the rotors hit anything.
Disadvantages :-
1) It is costly & the most significant problem to date have been an ambitious development
schedule coupled with very limited funds.
2) The ambition is followed by complexity in calculation & designing.
Conclusion:-
While the initial goal of creating an autonomous quadcopter, We used an information
for quadcopter frame selection and control. We learned important soldering & mechanical
Balancing, Motors Frame, Design and electric system fabrication skills including making a
power harness and digital to analog motor control. Our group all became proficient Arduino
programmers by necessity as it was the most complex part and required a group efforts.
