That's pretty amazing. o_O And they actually started looking for an absense of light? Wow.
It's not suprising.
If this is newsworthy at all, and I would argue that it's not, it is because this 'feat' was achieved with unguided evolutionary programming. The robotics itself is quite unsophisticated, and so one might wonder: why even perform this experiment with actual robotics when one could have more quickly and cheaply did the same experiment through simulation?
