Harvard Bee Robot Mass Production

The Harvard Robobee team has patented a mass production manufacturing process of micro aerial vehicle with insect-like form and size. Until now the manufacturing was artisanal but now this inspired from pop-up books new process allows fast production with incredible tolerance.
The next step is to develop the collective behaviour and intelligence of bee colony.
The applications will be from flower pollination to military surveillance.
