Overview of Quadcopters: Lift, Movement, and Components
A quadcopter is a versatile multicopter with four rotors, enabling vertical take-off, hovering, and slow flying capabilities. This rotorcraft excels in surveillance and search & rescue operations in cluttered environments but faces stability challenges in external disturbances. Components like motors, ESCs, flight controllers, and propellers contribute to its structure and flight control. Understanding functions like yaw, pitch, and roll aids in piloting this symmetrical vehicle efficiently. Explore the advantages and disadvantages of quadcopters along with details on key components like brushless motors.

Presentation Transcript
A Quadcopter also called a quadrotor helicopter, quadrocopter, quadrotor and quadracopter, is a multicopter that is lifted and propelled by four rotors. Quadcopters are classified as rotorcraft, as opposed to fixed- wing aircraft, because their lift is generated by a set of revolving narrow-chord airfoils. Quad-copters are symmetrical vehicles with four equally sized rotors at the end of four equal length rods.
ADVANTAGES DISADVANTAGES More lift VTOL Potential to Hover Surveillance Search & Rescue in hazardous cluttered environment Slow flying capability Less stable due to external disturbances. Less flight duration If any motor fails then it becomes very difficult to control
Rudder(Yaw) function:- Left rudder: M1 & M3 decreases M2 & M4 increases Right rudder: M1 &M3 increases M2 & M4 decreases
Elevator (Pitch)function:- Up Elevator: M1 increases & M3 decreases Down elevator: M1decreases & M3 increases Aileron(Roll) function:- Left Aileron: M2 increases & M4 decreases Right Aileron M2 decreases & M4 increases
