 I also think of the small scale, very small insects with very few neurons in their whole body are able to fly, to forage and to survive.   they do a lot with very little cpu power.

Actually in many insects the movements are not conscious -- e.g. Cockroaches use hairs at their tails to detect air currents (such as a human foot coming down on them) and their nervous systems autonomously make then run away to escape -- making a simple robot to do this is more about the hardware to detect the air currents than the logic required to trigger the running response.
