Swarm robotics is an approach to the coordination of multiple robots as a system which consist of large numbers of mostly simple physical robots. ″In a robot swarm, the collective behavior of the robots results from local interactions between the robots and between the robots and the environment in which they act.″
This could perhaps be applied to an AWE farm where the units are structurally independent but are evolving according to the other units and the environment. The respective tethers can be a challenge.
Another configuration is a kite network (Daisy type, or The Pyramid with the connections by ropes between the three units) where units are structurally connected. Perhaps in the end the whole could be seen as a single unit, but a more or less complex one for robotics.
