  • Yes, the bed and the environment in general is part of the world model. What I mean is that’s part of object identification and recognition of what objects to use for what task, etc. It’s a separate concern from dexterity. Think of it this way. If you’re thirsty, and you pick up a cup. You’re consciously thinking about moving your hand to grab the cup and bring it to your mouth. That’s what the world model is concerned with. You’re not aware of every individual muscle movement and all the micro adjustments that need to happen in order for the task to be completed. And that’s what the running illustrates. It’s the dexterity of the system in dealing with feedback from the world and making these adjustments in response.



  • You absolutely do have the impact of random events when you’re doing anything in the physical world. You have wind, uneven ground, variations in weight distribution, and so on. That’s what makes this sort of stuff so difficult in practice. All the tiny little errors quickly add up, so you can’t just match expected input. You have to have a dynamic system that can adjust on the fly to the sensory data. Dealing with stuff like an uneven bed or a tilted surface is a completely separate problem of having a good enough world model internally.
