The only base-homing method I know about that works fairly well is the one that Roombas and the RBs use-namely an odd number of IRLEDS pulsed at varying rates on the base that the bot can detect so it knows if it's to the left/right of center or heading right for it.
Sabre explained a little bit of how the Hero 2000 does it, but I didn't get the meat of it. Of course there are "cognitive" systems like Loki uses, but that's not perfect:any number of things can throw off the sensed relative location.
So I guess I'm asking what other systems and methods you guys like for homing, and can you give an explanation of it that an average TV viewer would understand?
