A permanent fixed connection to the ground severely restricts a
drone's mobility. The contact to the ground should be designed
to be as free as possible from repercussions on the flight
characteristics of the drone. Therefore, a felixible connection
by means of a rope, a cable or something similar must be chosen.
This leads to the problem that the string can get caught in one
of the rotors and thus cause the drone to crash in the worst
case. In addition, you need two hands to control the drone
including its camera function. A second person is therefore
needed to ensure that the cord does not get caught in the rotor.
