The article discusses the insect-like micro air vehicle (MAV). A PBS show recently showed some of these in action. Trying to design a computer like an insect's brain is apparently pretty tricky. According to the author, 98% of the insect's brain neurons are for sensory processing. So imagine all the little tiny sensors necessary, and the little tiny computer that has to take all the inputs and take action while flying.
