The controlling computer receives the position and publishes waypoints which the quad tries to follow.
All that information is passed along between the different components on the local network.
All of these components are prone to failure: The laser scans can report wrong information, or just don't report any information.
The quad mechanics or electronics can be mis-wired which may lead to applying wrong controlls controls to the motors. The position sensor suffer from
the same types of errors like the laser scanner and the ground computer may be buggy, may have virus, or may just use a wrong algorithm.
So, when you start the quadrocopter you expect that it will follow the dots in the map. You let it fly and it reaches the turning point very quickly,
but it doesn't turn. Disappointed, you stop the
