Interesting piece on Wired titled “Bye Swarmbots, Hello Swarmanoids” (Link). This seems to be an alternative approach to polybots (reLink). From the article:
A team at the Free University of Brussels in Belgium is embarking on a 42-month research project to build and test a 60-strong swarm of small, autonomous robots — the swarmanoid — capable of collaborating in 3-D environments.
I like the division labor approach:
The three types of bots will join forces to create a swarmanoid and perform various jobs. The footbots will transport objects on the ground level, while handbots with specialized climbing and grappling features take to the walls. Some eyebots equipped with visual sensors will operate attached to the ceiling, overseeing the action below and feeding information to their robotic colleagues; others will fly.
