Has anyone out there used a chip or circuit to detect sine waves? I'm looking to build a bot that can roam the backyard but stays within the boundaries of my dog's wireless fence.
Sounds like you need a buried fence detector. This has been done with the Robo-Cut mower and a few other robots. Basically it involves a frequency detector circuit which ultimately outputs a high when the buried/invisible fence is in close proximity. Try searching for buried fence detectors on Google if nobody can point you to a ready-made circuit. Take care.

Hi, i have been·researching this problem for a couple of months and have found several different people who have published on the net.
I am not an electronics Whizz so am very slow actually breadboarding a system. I own (i bought for my parents) a Mowbot which uses this type of containment system and have found the following two sites best :-
If you would like to join with me in using the UDO-5 one then we could split the costs of PCB production, there seem to be files with the layout but i do not understand them. Perhaps some one else who understands PCB production can advise whether these plans could be sent to a cheap PCB manufacturer - i dont fancy making my own as it sounds too complicated. ·

this one uses I2C to comunicate so both the transmitter and receivers can be a standalone modules.

this one uses a Basic Stamp and has the full robot but the electronics are a bit more sketchy.
