Is that completely true?
When I walk around in a familiar dark room, I have a model of the room in my
mind.
I use walls to help realign myself in my model of the room. Doorways and
furniture help calibrate my position. I know about how far I move with each
step which is very helpful with getting across a room in the absence of sensor
information. Of course, the assumptions are incorrect at times, feeling the
"wrong" doorway and wondering why there is a wall where the hallway should be
or why there is a sink in the bedroom.
I wonder if I was confined to a 2 wheeled differential drive platform and
had no vision (ever), what would happen then?
