I did no work on the mouse brain for some weeks, and then faffed around with various approaches that didn’t pan out. It’s now at a point I’m fairly happy with:
- the mouse has a simple algorithm for following a wall
- it generally does that without getting stuck, though there’s still some glitches
- it has no mental map of the world, or even the concept of a wall, just memory of the last thing it was doing
- it has no explicit goal
So the brain is really very dumb indeed, but it will make a good test bed when I do want to work on those things. I’m going to park it for now and move on to play with natural language.
