What are Throttle, Yaw, Pitch and Roll?

Drones/quadcopters are a bit more complicated than RC cars or boats.  For starters, they have four individual motor controls and travel in 3D space.  These problems alone make maneuvering and programming drones challenge.

To simplify things, in 3D space we use Euler’s Angles for orientation.  This lets us describe our drone’s motion and direction with 4 distinct maneuvers:  Throttle, Yaw, Pitch and Roll

Throttle is the vertical up and down motion of the drone.  Adding throttle will make the drone fly higher and reducing throttle will make the drone fly lower.

Yaw is the left and right rotation of the drone.  Adding yaw will make the drone spin to the right and reducing yaw will make the drone spin to the left.

Yaw Thin

Pitch is the forward and backward tilt of the drone.  Adding pitch will make the drone tilt and move forward and reducing pitch will make the drone tilt and move backwards.

Pitch Thin

Roll is the side to side tilt of the drone.  Adding roll will make the drone tilt to the right and reducing roll will make the drone tilt to the left.

Controlling the CoDrone

By default (Following this wiring guide and the default flight code):

Throttle is controlled by the left joystick’s up and down motion.

Yaw is controlled by the left joystick’s right and left motion.

Pitch is controlled by the right joystick’s up and down motion.

Roll is controlled by the right joystick’s right and left motion.

Remote Joysticks

 

Stop is controlled by the left IR sensor (bt1)

Landing is controlled by the right IR sensor (bt8)
