Auto-Return Obstacle Avoidance Process - Autel Robotics Alpha User Manual

25 meters < Distance from the
home point ≤ 50 meters
Distance from the home point >
50 meters
Note
 Home point: the point where the aircraft will return and land during an auto-return.
 Aircraft distance refers to the horizontal distance from the current aircraft to the home
point.

Auto-return Obstacle Avoidance Process

When the obstacle avoidance system is enabled and the visual sensing system is in appropriate
lighting conditions, the aircraft will achieve obstacle avoidance during the return process. The
specific situations are as follows:
 During manual flight, in case of a lost action auto-return, low battery auto-return, or manual
activation of auto-return, when an obstacle is detected in front of the aircraft, the aircraft will
automatically brake within the set brake distance and automatically ascend to avoid the
obstacle until it can safely fly over it.
 During flight missions, the obstacle avoidance mode is set to "Bypass". In the case of a lost
action auto-return, low battery auto-return, or mission completion auto-return, when an
obstacle is detected in front of the aircraft, the aircraft will automatically brake within the set
brake distance and autonomously choose a random direction from the left, right, or upward
directions to bypass the obstacle.
Important
 During the obstacle avoidance process, if the aircraft's ascent altitude reaches the
maximum altitude limit and obstacle avoidance is not yet achieved, the aircraft will hover
in place until a critically low battery landing is triggered. In this case, please manually take
control of the aircraft in advance.
 When the obstacle avoidance mode is set to "Bypass", the aircraft will prioritize planning to
bypass the obstacle from the left or right direction. If neither left nor right directions are
feasible, it will choose to bypass the obstacle from above.
If the current flight altitude is higher than 20 meters, the
aircraft returns to the home point at the current altitude.
If the current flight altitude is lower than 30 meters, the
aircraft ascends to the altitude of 30 meters and returns
to the home point.
If the current flight altitude is higher than 30 meters, the
aircraft returns to the home point at the current altitude.
If the flight altitude is lower than the set RTH altitude, the
aircraft ascends to the RTH altitude.
If the flight altitude is higher than the set RTH altitude,
the aircraft returns to the home point at the current
altitude.
