One year ago, we posted an article on this same blog that introduced a wheeled mobile robot that could move passive lures inside an aquarium to interact with living zebrafish Danio rerio. During the past year, we have been able to design an active lure, RiBot, that is equipped with an actuated tail in order to mimic the fish body movements underwater. RiBot is a combination of the words “Riba” (рыба) and “Robot” (робот) that means respectively fish and robot in Slavic language. This remotely controlled and waterproof device has a total length of 7.5 cm which is only 1.8 times the size of a zebrafish and is able to beat its tail with different frequencies and amplitudes, while following the group of living animals using the external wheeled mobile robot that is coupled with the robotic lure using magnets. An infrared universal TV control with RC5 protocol can be used to change the different beating tail modes. The robotic lure is also equipped with a rechargeable battery and has an autonomy of more than one hour.
Preliminary experiments of mixed societies of an actuated lure combined with an external wheeled robot and zebrafish Danio rerio will be presented at the SWARM 2015 conference in Kyoto, Japan
