This video shows the CoCoRo autonomous underwater vehicles (AUVs) in a large aquarium at the CeBIT exhibition.
This experimental setup simulates a real mission scenario in which the AUVs have to collectively find an object of potential interest at the sea floor (e.g., a black box of a crashed plane).
In the beginning the AUVs start randomly distributed in the mission area (= aquarium) where the object is assumed to be.
The AUVs do not perform a special search pattern but instead use a simple random walk. Due to the high number of AUVs, quite soon one of the AUVs will be near the object (in this case a magnetic target) and can perceive it.
The AUV then tries to keep its position above the object and starts to emit blue-light signals that attract other nearby AUVs which in turn also emit blue-light signals. This leads to a fast aggregation of most of the swarm AUVs near the object.
In future underwater swarms these AUVs could then collectively grab and lift the object to the water surface.
