The Husqvarna Automower relies on a boundary wire to tell the mower when it needs to stop and turn around. This is *really* important if you have a drop-off in your garden, like I do at the moment! If the mower can’t detect the boundary, it could drive itself right over a tiny cliff, or into a pond, or something dangerous like that. So what happens if the power fails while the mower is operating, and the boundary wire stops working? Let’s try it and see what happens!
