HA! That is all wishful thinking, not even just the last part. This is public housing. Heck, this is ANY building. Do you think the building department has as-builts of a house from the 50s? a commercial plaza from the 70s? a condo from th 90s?? Not actually. I’ve surely tried that. I can wait a month to get rolls and rolls of original blueprints, sometimes, if they can find them, IF they ever filed them. Now, do you have a 24x36 scanner and a couple CAD operators laying around for cheap?
Those plans are just not in a ‘close enough’ 3D CAD file in my computer. That’s a lot of work to do to take those and work them into 3D. We could put 3d sensors and cameras on existing and other robots and integrate their operation. Google’s done it to the outside of my house, I don’t really mind them having done so from the inside at some point, as it’s exactly the sort of info i’d like when looking at purchasing a structure, or painting it, or looking for problems in it.
The roomba aspect is one sort of way to collect parts of the dataset I envision as being useful. Working from plans is great and all, but they’re not as-built, and they’re a lot more work than going and looking yourself - which is the very problem they’re looking to solve.
