The point is to avoid the need to "program routes" or "determine current room". The LLM is supposed to have the world-understanding that removes the need to manually specify what to do.
Determine current room is a step GPT-4 would take care of by looking at the surroundings. The one thing I wasn't sure it could do, was figure out the layout of the house and determine a route for that. And I would rather provide it with some routes than have it wander around the house for an hour. I didn't figure real time video is what it was going to be best at. But it can certainly say the robot is in the living room, it needs to go down the hall to the kitchen. And if the robot knows how to get there already, it just tells the robot to go. I am sure there is another model out there that could be slotted in, but as far as just the robot plus GPT-4 goes, it might not quite be there. Just guessing at how they could fit together right now.
