仿生水母机器人采用极致的仿生设计：以水凝胶为电极材料，通过静电液压驱动结构，使机器人含水量 达到90%以上，从形态到材质都高度贴近真水母。 "离开水体后，它的透明驱动结构更直观。"陶凯将机器人从水缸中取出，其机身全透明，并搭载了电路 板、集成微摄像头模组以及嵌入式人工智能处理芯片。"这些脚蹼通过收缩舒张制造水流，实现推进与 悬浮，全程几乎无声、无明显扰动。"陶凯解释，这种设计让机器人在深海中如同"隐身"，可避免对海 洋生物与环境造成干扰。 实验室内，红、白两色的水母在水缸中自由移动，而旁边的仿生水母机器人几乎与水中环境融为一体， 如果不仔细看很难察觉。 这款直径仅120毫米、重量56克的微型机器人，是西北工业大学机电学院陶凯教授团队自主研制的仿生 水母机器人。机器人凭借近乎透明的躯体和仿水母肌肉结构，精准模拟了水母利用涡环推进的灵动姿 态，在水下实现高效且近乎无声的静默运行。 海水的平均密度远高于空气，物体在海水中移动十分困难。传统机器人进行海底探测时，不仅耗能巨 大，还会扰动起海底沉积物，干扰探测作业。"如何成为海洋中纯粹的观察者，而非干扰者？这是深海 探索的难题之一。"陶凯说，"仿生水母机器人正是面向深海 ...

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].

Group 1 - The A-share market opened lower on October 28, with the robot ETF fund (562360) remaining flat in early trading, while stocks like Oatmeal Technology rose over 7% [1] - The robot ETF fund (562360) has seen a net inflow of over 10 million yuan in the last four trading days, indicating strong investor interest [1] - The fund tracks the CSI Robot Index, which includes stocks from system solution providers, digital workshop integrators, automation equipment manufacturers, and related companies [1] Group 2 - According to Dongfang Securities, China's robot industry chain has strong manufacturing advantages, and companies are continuously expanding overseas production capacity, reducing uncertainty from external factors [2] - Leading robot companies are maturing their products and are about to enter mass production, suggesting a potential opportunity for investment in the sector [2]
