Core Viewpoint - The article discusses the development of a bionic jellyfish robot inspired by the natural propulsion system of jellyfish, which offers significant advantages over traditional underwater robots, particularly in energy efficiency and maneuverability [1][2][4]. Group 1: Technical Innovations - Traditional underwater robots, such as Autonomous Underwater Vehicles (AUVs), face challenges including high energy consumption, short endurance, and poor maneuverability due to reliance on propellers [1]. - The bionic jellyfish robot utilizes a unique propulsion mechanism that mimics jellyfish movement, achieving energy consumption that is only 1/10th of traditional propeller systems [1][4]. - The robot's design includes a lightweight structure with a total weight of 287 grams and dimensions of 110 mm in diameter and 159 mm in height, making it one of the lightest in its category [12]. Group 2: Propulsion and Steering Mechanism - The propulsion system is driven by a cylindrical cam mechanism that simulates the jellyfish's contraction and expansion, generating a thrust of approximately 0.75 N, sufficient to move two eggs [5][12]. - The steering mechanism employs an eccentric cam that allows for asymmetric movement of the tentacles, enabling the robot to turn without traditional steering systems [6][8]. - The robot can achieve a maximum turning speed of 22.7°/s and can perform complex maneuvers, including 90° and 180° turns, with a maximum turning angle of 200° [15]. Group 3: Performance Testing - In controlled tests, the robot achieved a maximum average swimming speed of 7.5 cm/s, which is competitive among existing bionic jellyfish robots [12]. - The robot demonstrated excellent adaptability in real-world environments, maintaining stable propulsion and maneuverability even in complex aquatic settings with minimal disturbance to surrounding marine life [18][21]. - The experimental results showed a high correlation between predicted and actual performance, validating the design's effectiveness and reliability [11][12].
