Abstract:
Our project will be in two stages. First stage will be: building a quadcopter that
has manoeuvring capability that can move up, down, left, right, forward and
backward. The control of the quadcopter will be done using RF module i.e.
Receiver and Transmitter Module. Further the stabilization will be done using
sensors like gyro, accelerometer mounted on the board. The second stage will be:
using camera output for crowd estimation. This can be done in two ways, first
recording the data during the in-flight and processing it post flight and the second,
video transmission using live feed from the camera and processing it in real time
mode.
Quadcopter:
Quadcopter is a quad rotor based helicopter that is lifted and propelled by four
rotors. Unlike helicopters they use symmetrically pitched blades. Control of
vehicle is achieved by altering the pitch and/or rotation of one or more rotor
discs, thereby changing its torque load and thrust.
The quadcopter design was chosen for this project due to its high degree of
stability and lifting power. The design consists of a symmetrical array of four
motors commonly attached with an ‘X’ shaped frame. The rotation direction of
the motors is alternated, so opposite motors spin in the same direction, to
counteract the reaction torques produced by the rotors. This design eliminates
the need for a yaw stabilizing rotor commonly used on helicopters.
The use of multiple rotors allows the vehicle to have a large lift capacity. For our
design we will aim to build a quadcopter with a lifting force that is double its own
weight.
Applications of quadcopter:
Research platform
Quadcopters are a useful tool for university researchers to test and evaluate new ideas in a number of different fields, including flight control theory, navigation, real time systems, and robotics. In recent years many universities
have shown quadcopters performing increasingly complex aerial maneuvers. Swarms of quadcopters can hover in mid-air, in formation, autonomously perform complex flying routines such as flips, darting through hula-hoops and organise themselves to fly through windows as a group.
Military and law enforcement
Quadcopter unmanned aerial vehicles are used for surveillance and reconnaissance by military and law enforcement agencies, as well as search and rescue missions in urban environments.[22]
Commercial
The largest use of quadcopters has been in the field of aerial imagery although, in the USA, it is currently illegal to use remote controlled vehicles for commercial purposes. Quadcopter UAVs are suitable for this job because of their autonomous nature and huge cost savings. Capturing aerial imagery with a quadcopter is as simple as programming GPS coordinates and hitting the go button. Using on-board cameras, users have the option of being streamed live to the ground.
