video video



Components

The Brushless Controller

Brushless DC Motors

Propellers(blades)

Receivers

Transmitter

Frame

Battery

Extra components

Cameras

GPS

Ultrasonic ranger

ELECTRONIC SPEED CONTROLLER

An electronic speed control or ESC is an electronic circuit with the purpose to vary an electric motor's speed, its direction and possibly also to act as a dynamic brake.

ESCs are often used on electrically-powered radio controlled models.

Brushless DC Motors

A brushless DC motor (BLDC) is an electronically controlled commutation system, instead of a mechanical commutation system comprising brushes and a commutator.

In such motors, current and torque, voltage and rpm are linearly related

Propellers(blades)

Two kinds

Pusher propellers

Puller propellers

Frame

Materials used:

Carbon fiber

Aluminium and its alloys

Thermocol

Extra components

Cameras

GPS

Ultrasonic ranger

FEATURES

Increased thrust and maneuverability

Functions in small areas

Quiet and efficient

Maintenance free

Fly up to 50 feet and more with a speed of 50 km/h for 30 min using a Li-Po battery.

APPLICATIONS

Quadcopter has applications in the following areas

1. Media

2. Fire & safety department

3. Police department

4. Forest department

5. Educational institutions

6. Civil engineering

7. Defence and military

ADVANTAGES OVER SINGLE ROTOR

The use of four rotors allows each individual rotor to have a smaller diameter than the equivalent helicopter rotor, for a given vehicle size, allowing them to store less kinetic energy during flight. This reduces the damage caused should the rotors hit any objects.

With their small size and agile maneuverability, these quadrotors can be flown indoors as well as outdoors.
