According to information published by “Kommersant,” Russian researchers affiliated with MIPT, I. Kant Baltic Federal University, and Lobachevsky University have engineered a distinctive fish-like robot. This prototype mimics the anatomy and swimming style of the yellowfin tuna, recognized as one of the ocean’s fastest fish. The objective of this creation is to serve as a foundation for developing fully autonomous systems capable of independent navigation within challenging underwater settings.
The engineers devised an innovative tail propulsion mechanism: a servo motor utilizes metallic cables to reshape a flexible plate, thereby producing a smooth, undulating thrust. The physical structure also incorporates steerable fins and a ballast tank for depth control, with the device powered by a lithium-polymer battery. The robot is equipped with an advanced sensor suite that compensates for sight and hearing. Sonar capabilities enable it to “feel” its surroundings acoustically up to a distance of 6 meters. An inertial measurement unit continuously monitors the orientation and rotational movements of the body. Furthermore, the robot features a camera system, allowing it to identify objects even in turbid water (during testing, it successfully read markers from 1.5 meters away under poor visibility conditions).
The primary scientific merit of this undertaking lies in its potential for integrating neuromorphic algorithms. The research team intends to construct an artificial spinal cord that will inherently generate rhythmic tail movements, adapting to environmental shifts without external human commands. To achieve this goal, the scientists are exploring the implementation of memristors—electronic components possessing memory functions that operate analogously to biological brain neurons.
