easiest to allow the Robomow to bump into them, causing the bumper sensor to activate and assist in
navigating around them. If there is a doubt whether to leave a specific obstacle without the perimeter wire
around it or not, the best way to determine is to drive Robomow manually towards the obstacle Obstacle
can be left without the perimeter wire around it, only if the front bumper responds when hitting the obstacle,
from all directions Young, sapling aged trees are not good examples, as they are not very rigid. Other
obstacles that are not rigid and at least 6 inches high (15 cm) must be protected from the Robomow using
the perimeter wire. This is done as part of the setup process and is commonly referred to as a perimeter
island. Good examples of these types of obstacles are flowerbeds, islands, small trees and low bed
edging.
The Robomow is designed to easily work in the lawn with both types of obstacles, however, for the most
gentle and silent operation, it is preferable to demarcate all fixed objects in and around the working area. If
you are unsure about a particular obstacle, it is best to exclude it with the perimeter wire. It will have no
effect on the efficiency of the mower and can later be removed if not needed.
To create a perimeter island, take the wire from the perimeter section closest to the obstacle and peg it
ground the obstacle, using the Roboruler distance around the obstacle, returning back to the same spot of
the edge you started from. The wires leading to the perimeter island and coming back to the edge should
be parallel and touching BUT they cannot be crossed. The gap between the wires shown at figures 1.13
for illustration purposes only. The wires to and from the perimeter island can be secured with the same
pegs. The mower will not recognize these two wires and mow over them as if they do not exist. The single
wire around the perimeter island will be recognized and prevent the mower from entering this area.
