Making a perimeter wire for my robot mower

Projects General Guidance
1

Heya, so I recently bought a Husqvarna 420 robot. But I have two lawns separated by a bit of road, one main lawn, which I will run the perimeter wire the usual way, and then a second small bit of grass which doesn't need to be cut that often but would be nice to get the robot to do it.

So, it IS possible to run the perimeter wire under the road, then over to the second piece of grass and have one closed system perimeter wire, but then I have the re-tarmac the road, and if I need to replace the wire, I am screwed. I think it is possible to use an Arduino to create a secondary perimeter wire, I have seen some projects like this online, but I am a little confused. How do I know what frequency the Husqvarna robot uses? I surely'd have to run it at something specific, right?

TLDR; How hard would it be to make a perimeter wire, that does NOT connect to the base station that the Husqvarna will pick up on? (And yes I know it won't cross the road itself. I would have to carry it across, which is fine.) Thanks!

Not if you bury duct and tread the wire through the duct.

I have no idea about the rest of your question.

not necessarily..
Trench under road..

It entirely depends on Your knowledge, experience, Arduino skill, electronics.

Use 2 lawn movers is a suggested option. Arduinos ar not any magicians.

Rhetorical question: How would the robot, following the perimeter wire, know to stop before crossing the road?

Then there is , look right, look left, then look right again before crossing....(assuming one drives on the left) :rofl:

A: It asks the chicken .

Why not have two separate loops and physically move the mower yourself .
