The Year of CoCoRo 37A/52: Again, we bring 2 videos online this week on "The Year of CoCoRo". This video shows an explanatory computer animation of our "combined scenario #2", which is again a variant of a collective search scenario. In a fragmented habitat only one compartment holds the magnetic search target. In every compartment a swarm of Jeff robots searches the ground. The Jeff robots that find this target inform Lily robots that spread this information into other compartments by moving randomly. As soon as Jeff robots, that did not find search targets in their current compartment so far, are informed that other Jeff robots somewhere else have found something, they rise up to the surface, make a random walk and then sink down to the ground again into a randomly chosen new compartment. Over time the whole swarm of robots converges to the one place where the target was found. By signaling upwards by Jeff and Lily robots, also the surface station is attracted to the place above the search target.
