I'm not sure yet if I should use the wire for full guidance or only as a lawn edge detector and let the mower move randomly within the lawn. I would lay the wire on top secured with big staples and let the grass grow over it.
Thanks cr0sh. What a great idea! I'll check into it. I looked into it. Seems that the tracer sensor needs to be within a few mm of the wire. I need a sensor distance up to about a meter. =(Thanks anyway!
Well done I have a friendly robotics lawn mower that I would like to hack with your approach. My lawn mower starts to spin the wheels when it tries to go up a hill steeper than 15 degrees...It would be nice to detect slippage of wheels and change direction when this is detected. Does your yard have many hills? Maybe the weight/wheel chair wheels don't have this issue
