Build A Quadcopter From Scratch - Hardware Overview

In this article I will be talking about quadcopter components and how to choose them. This is part of the tutorial series on how to build a quadcopter. In the next post I will be talking about software, how to go about the algorithm and programming. If you are planning on building a quadcopter but not sure how, this is the right place for you. Building a quadcopter from scratch takes a lot of time and effort. For more tutorials, check out this list. This blog post is divided into a three parts What is a Quadcopter and How It WorkQuadcopter Components IntroductionConclusion A QuadCopter is a helicopter with four rotors, so it’s also known as quadrotor. The Quadcopters exist in many different sizes. On a regular helicopter has one big rotor to provide all the lifting power and a little tail rotor to offset the aerodynamic torque generated by the big rotor (without it, the helicopter would spin almost as fast as the propeller) Frame – The structure that holds all the components together.

Quadcopter Design Motors, propellers and ESCs For multicopters, motors, propellers and ESCs (speed controllers) are critical and have been failure prone in the past. This ECalc based Xcopter: motor - propeller - battery - ESC calculator will help you pick the best parts for your copter. Quadcopter design is featured here as they are the most wide spread and the most versatile. The QuadCopter Frame There are many types of frames and it is most important to put together a frame that is appropriate for your use. Multicopter frames are available as bare frame kits, Almost Ready To Fly or Ready To Fly copters. X Frame versus H or Dead Cat: Advantages and Disadvantages The Original X frame and more recent H or Dead Cat frames each have good and bad points. The original X frame design is a good all around choice. The Carbon Fiber or Fiberglass Tube and Plate Frame The carbon fiber or fiberglass tube and plate frame is popular because it is strong and light and easily manufactured.

Quadcopter Dynamics and Simulation - Andrew Gibiansky A helicopter is a flying vehicle which uses rapidly spinning rotors to push air downwards, thus creating a thrust force keeping the helicopter aloft. Conventional helicopters have two rotors. These can be arranged as two coplanar rotors both providing upwards thrust, but spinning in opposite directions (in order to balance the torques exerted upon the body of the helicopter). A quadrotor helicopter (quadcopter) is a helicopter which has four equally spaced rotors, usually arranged at the corners of a square body. The development of quadcopters has stalled until very recently, because controlling four independent rotors has proven to be incredibly difficult and impossible without electronic assistance. Quadcopter control is a fundamentally difficult and interesting problem. We will start deriving quadcopter dynamics by introducing the two frames in which will operate. Quadcopter Body Frame and Inertial Frame Kinematics where \omega is the angular velocity vector in the body frame. Physics
