Chapter 17 Glossary
Obstacle
An object in the field that the robot must avoid. Obstacles can be permanent (e.g.. trees,
furniture) or transitory, (e.g.. animals).
Obstacles are detected by sensors. Permanent obstacles can be avoided by making
loops in the peripheral wire to form "islands" or "pseudo-islands".
Parcel
An area to be mowed within a peripheral wire. At least one parcel is associated with one
wire.
Several parcels can be defined.
Percentage
This represents the proportion of time that the robot will spend working a particular parcel.
If there is only one parcel, the robot will spend 100% of its time there.
Peripheral wire
A wire laid below the surface of the field to be mowed which defines the area to be
mowed and controls the limits of the robot's movement. The area defined by the
peripheral wire is termed a "parcel".
Pseudo-island
The peripheral wire is taken around the obstacle, maintaining a specific distance between
the approach and the return wires.
Site
The entire area which includes the area to be mowed, as well as surrounding landscaping
that is not mowed.
Station loop
A station loop is a short wire around a charging station which is used to guide the robot
into the station. When the robot detects that it is in the station loop it follows the wire until
it arrives in the station.
Station positioning beacon
A device, usually installed in the charging station, that emits a signal that allows the robot
to accurately locate the charging station.
Terrain
An area of grass surrounding the field that is not to be mowed.
Track border
A width of grass around the edge of the parcel to be mowed. The robot follows the track
border when leaving or returning to a station.
There is no track border specified for a wire that acts as a "
201)".
Figure 115: Track border
The track border lies next to the peripheral wire, and is defined by minimum and
maximum dimensions set as installation parameters. It is wider than the robot. The path
taken by the robot within the track border is selected in a random manner. This ensures
