upward movement = this happens by having two propellers going clockwise and two going conter clockwise and being configured opposite to each other. Giving the same speed to all four propellers and being fast enough will give enough thrust for the quadcopter to float upwards.
downward movement = same concept with upward movement but having lower speeds than required to support the quadcopter weight.
forward movement = this happens by giving more speed to two backside propellers.
backward movement = this happens by giving more speed to two front propellerd.
sidways movement = this can be done by having two propellers opposite to desired movement rotate with more speed.
clockwise yaw = this happens by giving more speed to two propellers which rotate clockwise.
counter clockwise yaw = this happens by giving more speed to two propellers which rotate counter clockwise.
Balance is important for the basic quadcopter movements. therefore speed adjustments must be changed not too drastically.
One minor correction...
ReplyDeleteThe yaw control as shown in the diagram is correct, but inverted as worded, meaning:
The yaw direction would be opposite to the higher speed propellers because it's the body reacting to the torque of those motors.
