I've been looking into robotic lawnmowers, and they're basically the same. The more primitive ones have a hall effect sensor under their snout feeling for a wire you bury around the edge of your yard, and do the "go until you hit something, turn a random amount, repeat until low battery, follow perimeter to dock" or they require phoning home in some way, shape or form.
Meanwhile, some guy's got an open source system that runs on a Raspberry Pi on the mower itself.
I guess I'm willing to believe that some of the LIDAR or camera-only guided mowers need some serious processing power to create the maps they use for guidance around the yard, and that's more practical to do on the company's servers than on the device itself...except not really; we've got decently powerful ARM SoCs that don't cost much, don't take a lot of power to run, and can do that job. The reality is, you can't get a pedometer app for a smart phone that doesn't broadcast sensor telemetry to two continents these days.
