Robotic fish are nowadays developed for various types of research, such as bio-inspired robotics, biomimetics and animal behavior studies. In the context of our research on the social interactions of the zebrafish Danio Rerio, we developed a miniature robotic fish lure for direct underwater interaction with the living fish. This remotely controlled and waterproof device has a total length of 7.5 cm with the same size ratio as zebrafish and is able to beat its tail with different frequencies and amplitudes, while following the group of living animals using a mobile robot moving outside water that is coupled with the robotic lure using magnets. The robotic lure is also equipped with an easily rechargeable battery and can be used autonomously underwater for experiments of up to one hour. We performed experiments with the robot moving inside an aquarium with living fish in order to analyze its impact on the zebrafish behavior. We found that the beating rate of the tail increased the attractiveness of the lure among the zebrafish shoal. We also demonstrated that the lure could influence a collective decision of the zebrafish shoal, the swimming direction, when moving with a constant linear speed inside a circular corridor. This new robotic fish design and the experimental results are promising for the field of fish-robot interaction.

“…While the tail beating of the RiBot does not recreate the exact same hydrodynamic patterns that fish generate, it can reproduce the average tail beating range of the zebrafish that has been shown to be an attractive stimulus. [6][7][8] We have studied the locomotion behavior of zebrafish in a rectangular tank in order to establish a controller for the locomotion of the Fish-CASUs. First, we observed a heterogeneous spatial repartition of the linear speed of the fish in the aquarium.…”

“…In terms of size, we have smaller length, width, and height compared with other robotic fish designs while respecting more the shape ratio of a zebrafish. Finally, in terms of linear speed, in a study by Aureli et al, 7 the lure is moving autonomously underwater and thus its linear speed is quite small. In a study by Butail et al, 8 the lure is attached to a robotic arm that allows it to move with speeds up to 40 mm s À1 .…”

“…RiBot, the active soft robotic lure Based on related studies on zebrafish-robot interactions, [6][7][8] the lure acceptance among the zebrafish shoal can be increased when the lure beats its tail. It is also known that zebrafish can bend their caudal peduncle up to very high angle (up to p rad) with high angular velocities (up to 4.2 rad s À1 ).…”

Robotic animals are nowadays developed for various types of research, such as bioinspired robotics, biomimetics, and animal behavioral studies. The design of these robots poses great challenges as they often have to achieve very high-level performances in terms of locomotion, size, and visual aspect. We developed a robotic system for direct underwater interactions with small fish species. This robotic platform is composed of two subsystems: a miniature wheeled mobile robot that can achieve complex locomotion patterns and a robotic fish lure that is able to beat its soft caudal peduncle to generate fish-like body movements. The two subsystems are coupled with magnets that allow the robotic lure to reach very high speeds and accelerations, thanks to the mobile robot. We used zebrafish (Danio rerio) to model small fish locomotion patterns and construct a controller for the motion of our robotic system. We have demonstrated that the designed system is able to achieve the same types of motion patterns as the zebrafish while mimicking the body movements of the fish. These results define new standards for robotic fish lures and bring to the field of fish-robot interaction a new tool for ethological studies.

“…A single fixed camera can record 2D movements, in the laboratory (e.g. Aureli et al, 2012) or even outdoors (Pillot et al, 2010;Collett et al, 2013). 3D tracks in the field have been measured using multiple fixed cameras (Major and Dill, 1978;Pomeroy and Heppner, 1992;Ikawa et al, 1994;Budgey, 1998;Ballerini et al, 2008;Corcoran and Conner, 2012;Shelton et al, 2014).…”

We describe a method for tracking the path of animals in the field, based on stereo videography and aiming-angle measurements, combined in a single, rotational device. In open environments, this technique has the potential to extract multiple 3D positions per second, with a spatial uncertainty of <1 m (rms) within 300 m of the observer, and <0.1 m (rms) within 100 m of the observer, in all directions. The tracking device is transportable and operated by a single observer, and does not involve any animal tagging. As a video of the moving animal is recorded, track data can easily be completed with behavioural data. We present a prototype device based on accessible components that achieves about 70% of the theoretical maximal range. We show examples of bird ground and flight tracks, and discuss the strengths and limits of the method, compared with existing fine-scale (e.g. fixed-camera stereo videography) and largescale tracking methods (e.g. GPS tracking).
