This chapter describes the use of the Multizone option.
Your installation must contain the following elements if you wish to
use the multizone option:
-
A multizone station including multiple blue cards (2 or 3) to generate
a multi-zone signal across multiple magnetic loops.
-
Multiple (2 or 3) peripheral wire loops corresponding to the different
work zones set up during the installation process.
-
A robot with multizone software based on the hardware configuration
of your robot which you can ask or made install by you dealer.
(Please contact your Etesia dealer if you cannot find the software for
your robot hardware).
6•1 DESCRIPTION OF THE
MULTIZONE OPTION
The multizone option allows you to define multiple zones (maximum
of three zones) corresponding to multiple peripheral wire loops in
which the robot will work. The different zones possible are identified
in the software as ZoneA, ZoneB and ZoneC.
The station must be place on the 2 or 3 peripheral loops such that
the robot can return to the station from each of the work zones. This
means there must be an area of ground which is inside all 2 or 3
peripheral loops. This is called the recovery zone (see picture 37).
Thanks to the Multizone option, it is possible to improve the overall
cutting quality across the area by:
Considering complex installations where the use of multiple peripheral
loops of wire makes the installation simpler or even possible at all.
Example: a case where there are 2 distinct zones as illustrated
picture 38.
Using the Multizone option :
- allows controlled distribution of work between the two zones
and also reduces the time taken to return to the station by
reducing the distance to travel for each return to the station.
- guarantee the distribution of work you want between zones A,
B and C by means of parameters and options (see later in the
document) and allow the robot to work more efficiently overall.
- allows consideration of the restrictions on occupying the area
and not necessarily having to put the robot in the rest station
(backhome) if part of the area (one zone) is occupied, instead
the robot can work in the other zones.
Zone A = main football pitch occupied for competitions
during the weekend
Zones B and C = training areas (see picture 39)
With the multizone option, it is possible to set the system up so
that the robot can continue to work on Zones B and C during the
competitions at the weekends. Or vice versa, it can work on Zone A
during mid-week training sessions.
Considering different cutting or ball collection objectives for the
different sub-zones and guarantee the presence of a robot in the diffe-
rent sub-zones in order to achieve these objectives.
For a lawn-mower robot, the grass grows at different rates in the two
zones because of the nature of the soil or exposure to sunlight. It is
possible to arrange for the robot to spend more time in the zone where
the grass grows more quickly.

6•2 CHOICE OF WORK ZONE
6•2•1 AUTOMATIC ALGORITHM
The figure 1 illustrates the global algorithm for choosing the zone
and the way in which the user can influence the algorithm by means
of commands, parameters and options which can be given to /
programmed on the robot.
In automatic mode (normal operating mode), the robot chooses a
work zone for each cycle, i.e. each time it leaves the station to go and
work (steps 4 and 5 of the figure 1). During a cutting cycle (steps 0,
1, 2 of the figure 1), the robot never changes zone but still sometimes
passes through the recovery zone included in the selected work zone.
