The Year of CoCoRo 31/52: The first phase of our "combined scenario #1" is that the CoCoRo system, as a whole, enters the habitat. Then happens the only human intervention in the execution of the scenario: The swarm gets released by pressing a button performed by a human operator. This sends a WLAN signal that triggers the release of the swarm: For this very important security measure we kept the human in the loop on purpose, because a robot swarm is just a tool that a human operator, who is responsible for it, can use to achieve or facilitate a certain task. After the release of the swarm the Jeff robots sink to the ground of the water body and start their search for the metallic/magnetic target object while the Lily robots swarm out to later build the "relay chain" between the target spot and the surface station.
