Stones
If there are stones in the robot's cutting area, it is important to assess whether the edge of
the stone is higher or lower than 100 mm, and whether the stone should be protected or
removed to avoid damage to the robot.
For obstacles/areas that need to be left out of the cutting area by the wire, it is important to
follow the direction from which you have started. (See picture)
Slopes
The robot lawn mower can drive up and down slopes with a maximum gradient of 20°.
