In this post I will explain How to build Quadcopter.
How to Build Drone at Home in India
- What is Drone
Drone is commanly used for unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UAS). Drone can fly autonomously without human intervention or Pilots help. To achieve autonomy autopilot is used in drones.
- What is Autopilot
The literal meaning of autopilot is a device that steers a ship, plane, or spacecraft by itself, without a person . This is achieved using hardware and software. Autopilot has sensors like IMU, GPS , Barometer which estimate vehicles position in 3D space.
- List of Parts Required to Build a Drone
Here I will mention parts used for building Quadcopter
Electronic Speed Controller ( ESC )to control speed of motors
Autopilot or Flight controller
Transmitter and Receiver
Other items you will need are wires, 3.5mm bullet connectors, solder iron.
- Assembling Quadcopter Frame
We have to assemble quadcopter Frame. To assemble frame we need to follow instruction given in manual provided with frame.
- Mounting Motors
Each frame comes with motor mounting. We have to mount motors on the arms of frame. Make sure you tighten them firmly so that they will not loss due to vibration while flying
- ESC calibration
ESC have current rating on them with compatible battery make sure you are using correct ESC as per motor requirement.
ESC is calibrated using Transmitter. In calibration we store max and minimum value of throttle.
- AutoPilot configuration
Depending on our autopiot selection we have to configure it. Mostly used autopilot is Pixhawk 2.1 Cube. I will share another post with video tutorial on how to use Pixhawk 2.1
