"[T]each robots to be able to find their own solutions to complex problems." #readingToday  

The general philosophy here is to teach robots to be able to find their own solutions to complex problems. This is important for long-term reliable autonomy, because there's no way that we can possibly foresee all of the different problems that a robot might run into. And if you have some robots that are, say, exploring another planet and, I don't know, one of them gets stuck in a sand dune or something, you'd want it to be able to try stuff until it manages to get free, learning from each attempt as it does so.
