2. Operation principles of obstacle avoidane: Pulse signal is sent out by the
transmission port. The pulse signal is received by the receiving port after
the pulse signal returns once the obstacle found within the scanning range.
The forward stop command is sent out after the distance between aircraft
and obstacle is obtained by a series calculations.
3. The position of the aircraft stop to go ahead depends on the flight speed.
When the aircraft flys dead ahead in low speed, forward stop command
starts to sent out after the obstacle is scanned at the distance of 20 meters
to the aircraft. The obstacle avoidance distance of the aircraft and obstacle
is shorter if in high speed. Otherwise,it will be longer (20 meters at most).
