Wire recognition
The current in the wire creates a well defined
(conic shape) magnetic wave, which is seen by the
mower as shown here
magnetic wave outside the lawn is Negative

Wire recognition
Wire sensors peak the gradient in the wire
readings and the peak as soon as it starts
dropping down outside the wired area.
Inside the wire

Wire recognition - Virtual wall
The mower doesnt see the wire

Riding the wave on EDGE
Inside the lawn Positive
Outside the lawn Negative
This is how the mower tracks the wire One sensor
(blue/positive) is inside the lawn and the other
one (red/negative) is outside it.

The mower knows it is on the wire since the two
wire sensors on its left side are inside the lawn
and two wire sensors on its right side are
outside the lawn.

Reaching a corner on Edge mode
The mower knows it needs to turn left since
only one wire sensor (Rear left) is inside the
lawn and three others are outside.
