央视报道！哈工程最新研制成果“机器鱼”，4000米深海行动自如！

Core Viewpoint - The article discusses the development and significance of a new soft-bodied underwater robot that utilizes innovative electro-hydraulic actuation technology, enabling it to operate effectively in extreme deep-sea environments, overcoming the limitations of traditional rigid robots [4][10][22]. Group 1: Technology and Innovation - The soft-bodied robot measures 32 cm in length, has an 18 cm wingspan, and weighs only 670 grams, showcasing exceptional adaptability to deep-sea conditions [1][7]. - Traditional rigid robots struggle in the deep sea due to high pressure and complex environments, making soft-bodied robots a more suitable solution due to their flexible structure and minimal environmental interference [3][4]. - The research team led by Professor Li Guorui from Harbin Engineering University has pioneered the use of electro-hydraulic actuators (EHA) for deep-sea soft-bodied robots, which do not rely on external pumps, thus allowing for a more compact and flexible design [4][10]. Group 2: Design Features - The robot features a wave-shaped tail for propulsion, buoyancy modules for stability, and an integrated optical sensing module for height adjustment, enabling it to monitor its distance from the seabed continuously [7][9]. - It incorporates a micro deep-sea optical sensing system that allows real-time perception of its motion and environmental targets, enhancing its operational capabilities in extreme conditions [9][10]. Group 3: Performance and Testing - The research team successfully tested the robot in various depths, including a deployment at 3176 meters in the South China Sea, where it demonstrated reliable maneuverability and sensing capabilities under extreme pressure and complex flow conditions [17][21]. - The robot's innovative design allows it to perform complex trajectory movements and low-disturbance detection, marking a significant advancement in deep-sea exploration technology [22][24]. Group 4: Future Implications - The development of this soft-bodied robot represents a breakthrough in deep-sea exploration, providing a powerful tool for marine scientific research, resource exploration, and environmental monitoring [22][10]. - The integration of artificial intelligence and robotics is expected to drive significant advancements in ocean development, making the ocean economy a vital growth point for coastal regions [22].
