- The body frame follows the Front Left Up (FLU) convention, and right-handedness.
- Frame Convention:
- X axis is along the **Front** direction of the quadrotor.
| Clockwise rotation about this axis defines a positive **roll** angle.
| Hence, rolling with a positive angle is equivalent to translating in the **right** direction, w.r.t. our FLU body frame.
- Y axis is along the **Left** direction of the quadrotor.
| Clockwise rotation about this axis defines a positive **pitch** angle.
| Hence, pitching with a positive angle is equivalent to translating in the **front** direction, w.r.t. our FLU body frame.
- Z axis is along the **Up** direction.
| Clockwise rotation about this axis defines a positive **yaw** angle.
| Hence, yawing with a positive angle is equivalent to rotated towards the **left** direction wrt our FLU body frame. Or in an anticlockwise fashion in the body XY / FL plane.

roll (float): Desired roll angle, in radians.
pitch (float): Desired pitch angle, in radians.
yaw_rate (float): Desired yaw rate, in radian per second.
