“…Especially fish behaviour has been investigated with biomimetic robots [27 -29]. These robots consist of fish-like replicas that move either self-propelled [30][31][32] or dragged by an external vehicle or manipulator [29,[33][34][35][36][37][38][39][40][41][42][43][44][45][46]. Self-propelled robots are often large as all necessary technical equipment has to fit into the robot's chassis and thus can be used mostly for interactions with larger animal species [30,39,47].…”

Externally dragged and steered robots can be much smaller because most technical equipment is peripheral and thus can be used to investigate smaller species [27].…”

Using a robotic fish to investigate individual differences in social responsiveness in the guppy

Responding towards the actions of others is one of the most important behavioural traits whenever animals of the same species interact. Mutual influences among interacting individuals may modulate the social responsiveness seen and thus make it often difficult to study the level and individual variation in responsiveness. Here, open-loop biomimetic robots that provide standardized, non-interactive social cues can be a useful tool. These robots are not affected by the live animal's actions but are assumed to still represent valuable and biologically relevant social cues. As this assumption is crucial for the use of biomimetic robots in behavioural studies, we hypothesized (i) that meaningful social interactions can be assumed if live animals maintain individual differences in responsiveness when interacting with both a biomimetic robot and a live partner. Furthermore, to study the level of individual variation in social responsiveness, we hypothesized (ii) that individual differences should be maintained over the course of multiple tests with the robot. We investigated the response of live guppies (Poecilia reticulata) when allowed to interact either with a biomimetic open-loop-controlled fish robot—‘Robofish’—or with a live companion. Furthermore, we investigated the responses of live guppies when tested three times with Robofish. We found that responses of live guppies towards Robofish were weaker compared with those of a live companion, most likely as a result of the non-interactive open-loop behaviour of Robofish. Guppies, however, were consistent in their individual responses between a live companion and Robofish, and similar individual differences in response towards Robofish were maintained over repeated testing even though habituation to the test environment was detectable. Biomimetic robots like Robofish are therefore a useful tool for the study of social responsiveness in guppies and possibly other small fish species.

“…1 Among underwater robots, swimming robots have significant potential for study of marine life, monitoring oceanic environments, and underwater operations. [2][3][4][5][6][7] As a specific sea creature, jellyfish has a soft body, which is found in the waters all over the world. Owing to low metabolic rate, jellyfish has the ability to move vertically without expending much energy, while it passively depends on ocean current, tides, and wind for horizontal movements.…”

Jellyfish uses jet propulsion to achieve a diversity of propulsion modes in the water. In this article, a miniature jellyfish-inspired swimming robot is designed and built, which is capable of executing horizontal and vertical propulsion and maneuvers. In order to imitate the jellyfish in terms of morphology and kinematics, the robotic jellyfish is designed to be comprised of a streamlined head, a cavity shell, four separate drive units with bevel gears, and a soft outer skin encasing the drive units. A combination of four six-bar linkage mechanisms that are centrally symmetric is adopted as the driver to regulate the phases of contraction and relaxation of the bell-shaped body. Furthermore, a triangle wave generator is incorporated to generate rhythmic drive signals, which is implemented on the microcontroller. Through independent and coordinated control of the four drive units, the robotic jellyfish is able to replicate various propulsion modes similar to real jellyfish. Aquatic tests on the actual robot verify the effectiveness of the formed design scheme along with the proposed control methods.

“…Robotic fish is designed for swimming a liquid (Kheirikhah et al, 2010), and can be used in some cooperative applications such as research about the underwater environment, archaeology, finding patrol in the seas, and it can be used for research in some complex environment in-depth oceans. It is difficult for an ordinary robot because the motion should be well programmed (Yu, Chen, Wu, & Wang, 2016). The robotic fish can swim underwater using its wings and propellers (J.…”

There is a high demand for functional smart materials, especially for new material groups in advanced Technologies. These materials are used in the actuator, sensor, control systems, and robotic systems, in addition, they can be hybridized with traditional material to create a particular function. Piezoelectric materials and shape memory alloys are the most important families among these groups. This review includes an overview of shape memory alloys (SMAs) and piezoelectric material actuator systems in terms of robotic applications. The theoretical background of each SMAs and piezoelectric materials is well explained. Different types of each system are interpreted. Using actuator-based SMAs and piezoelectricity in the robotic area is extensively overviewed. Some weaknesses and challenges facing such systems have discussed through recent studies in the literature.
