Rubber is inert and non conductive. The problem had to be caused by something else. Was anything else changed at the same time?
Folks, I want to point out a "no signal" problem can be caused by many different things. Of all the Lawnbott problems that can happen, I rank it as the worst one because it is difficult to solve. Here is the list of possible causes:
*1) Loose wire
*2) Wire too long
*3) Distance is too far between wires (if "no signal" occurs in the same place in the yard all the time, this could be the cause)
*4) Loose connection between transmitter and base
5) Loose connection between power supply and transmitter
6) Loose connection between perimeter wire and base
*7) Loose connection at wire splice in yard
*
Bad transmitter
9) Bad power supply
*10) Receiver card loose in robot
*11) Receiver card problem
12) Motherboard problem
*13) Disturbance filter/signal booster remove/add
The ones with the * are the ones I've helped customers with. Others are possible but I have not had to deal
with them yet. Most often it is caused by a problem with the wire (loose or bad connection). We always recommend
soldering the connections. BTW - Changing the receiver card can sometimes fix it, but this does not mean the original
receiver card was bad. The original card would likely work on someone else's yard, like one with a shorter wire.
Removing the disturbance filter and/or adding the signal booster sometimes solves the problem. We had one case
where changing to a different style of blade motor solved the problem.
It's a safety feature to have Lawnbott detect the signal all over the yard (keeps it from running out of the border),
but personally, I think Zucchetti should re-think their strategy and/or only do that for small yards.
