point for the boundary.
Auto Boundary Detection
Powered by an advanced AI algorithm, the robot uses its front camera to detect grass and non-grass areas,
allowing it to identify boundaries without the need for manual guidance. After guiding the robot remotely to the lawn edge and setting the starting point, you can use Auto
Boundary Detection mode. You can choose whether the robot should cross the perimeter for cleaner edge cutting results or stay close to it to avoid getting stuck.
We recommend following the robot during this process. If the robot fails to accurately detect the boundaries, you can exit Auto Boundary Detection mode and switch to remote control at any time.
When the robot returns to within 1 m of the starting point, you can tap Close Boundary, and the boundary
will automatically be completed.
Set No-Go Zone
Though the robot can automatically avoid obstacles, it is still necessary to set areas with a risk of falling,
such as swimming pools and sandpits, as no-go zones. For DREAME Roboticmower A2 Car Boundary Device objects you want to protect (such as a flowerbed, a trampoline, a vegetable patch, or an exposed tree root), please set them as no-go zones. You can tap the ogo zone in the app to continue creating no-go zones. Alternatively, you can go to > Map Editing to create or delete the no-go zones after the map is finished.
To Create More Zones
If your lawn is separated by roads or you have several isolated lawns, you can tap Work zone in the app to
continue creating work areas. You can also add, delete, or modify the zones in > Map Editing when the
map is finished.
To Expand Existing Zones
To expand an existing zone, tap Work zone in the app to create the area you want to include. If the two
areas overlap, they will be automatically merged. Alternatively, you can go to > Map Editing > Work
