ONLINE COVER Go Fish! Colonies of insects, flocks of birds, and schools of fish are able to produce complex global behaviors through simple local interactions. Inspired by nature, Berlinger et al. achieve complex 3D collective behavior with fish-inspired robots called Bluebots. Using implicit vision-based coordination, a swarming school of Bluebots, called Blueswarm, demonstrated synchrony, aggregation-dispersion, dynamic circle formation, and search-capture behaviors. This month's cover is a composite photograph of a Blueswarm (see also the Focus by Wolek et al.) [IMAGE CREDIT: FLORIAN BERLINGER]
