To me its exactly the type of thing they should be conenctrating on with general robots. forget other tasks have it switch another robots batteries and then work on other maintenance tasks and then repair and then manufacture. If they can do that they will be able to do a bunch of other things and now if you have like 3 robots they can do a bunch of things and take care of each other. Rather than getting up from a fall how about another robot resuces a robot from a situation it can't get out of.
