Of course at this point there would be serious risk of one bot
downloading malicious code into another bot. Now suddenly the bots would
require an immune system.
It would turn into core wars!

I was thinking along the line of legged robots who are learning how to
walk from scratch, e.g. they have all the necessary hardware but they
need to 'come up' with the software.
Fitness is measured by the amount of movement over time, stability, and
smoothness of movement. Feeback from a couple of accellerometers in the
head and either GPS or a local 3D tracking system would be required.

(I have a theory about walking that I would like to test, namely that an
organism that can walk has learned how to move around while using the
least amount of energy, a simple fitness test!)
