Sure, but a simple address database seems like a lot easier way to get there than robots roving around houses with LIDAR?
Did Roomba ever use lidar? I thought their mapping feature was a camera pointing to the celling which is bringing in much richer data than lidar.
Robot vacuums with lidar don't even need internet connections to work.
Not sure that works though for flogging, say, client IP to affluency data to advertisers, unless they can already reliably pinpoint the client IP to an address (which for all I know, maybe they can).
