But how complete must the self-model be.
That is the 64 million dollar question.
As Bruno has pointed out, it can't
be complete. Current Mars Rovers have some "house
keeping"self-knowledge,
like battery charge, temperature, power draw, next task, location,
time,...
I don't think that's enough. I think it must have the ability to
recognise other (perhaps similar) robots/machines as being like
itself.
Of course current rovers don't have AI which would entail them
learning and
planning, which would require that they be able to run a simulation
which
included some representation of themself; but that representation
might be
very simple. When you plan to travel to the next city your plan
includes a
representation of yourself, but probably only as a location.
Hod Lipson's starfish's representation of itself is no doubt rather
simple and crude, but it does pose the question of whether it might
have some sort of consciousness.
There exists at least a "minimal system" comprising of the rover and
perhaps controllers on Earth that makes the rover capable of taking in
random information from its environment, interpret it and then take
whatever action is necessary to make sure it is able to stay clear of
trouble while performing certain tasks. The action it needs to take to
stay clear of trouble implicitly contains information about itself. Of
all the possible physical states the rover can be in, most correspond to
the rover being in a totally broken down state. Then there are also
ideal states and not so ideal states. The rover (with the aid of
controllers) is programmed to take action to prevent it from drifting
away to a less than ideal state and if it is in a less than ideal state,
it will take action to try to get back into a more ideal state.
