Core Viewpoint - The research conducted by the Harbin Engineering University team presents a novel deep-sea soft robot that operates autonomously, showcasing significant advancements in underwater robotics technology [3][5][17]. Group 1: Research and Development - The research was a collaborative effort involving Harbin Engineering University, Zhejiang University, and the China Ship Scientific Research Center, and it has been validated in various deep-sea environments, including depths of 1369 meters and 4070 meters [5][15]. - The robot measures approximately 32 cm in length and 18 cm in wingspan, weighing only 670 grams, and is designed to withstand extreme underwater pressure without a rigid shell [7][11]. Group 2: Technical Innovations - The robot utilizes an electrohydraulic drive mechanism inspired by the "electrohydrodynamics" phenomenon, allowing for precise control of its flexible components through the directional flow of dielectric fluid [11][13]. - A unique "electrohydraulic, plasticized medium integration" strategy was developed to maintain the flexibility of the polymer shell while ensuring efficient actuation, utilizing surrounding seawater as an alternating electrode to enhance performance [13][15]. Group 3: Functional Capabilities - The robot is equipped with a miniaturized energy control system that enables coordinated movement, allowing it to perform various maneuvers such as straight-line motion and turns in response to electrical signals [13][15]. - It features a micro deep-sea optical sensing system that provides real-time awareness of its movement and environmental targets, enhancing its capabilities for near-bottom sensing in extreme conditions [13][15]. Group 4: Testing and Future Directions - The team conducted extensive sea trials, demonstrating the robot's ability to perform complex trajectory movements and environmental sensing tasks in challenging underwater conditions [15][20]. - Future research will focus on interdisciplinary integration of driving, sensing, and communication systems for small deep-sea soft robots, aiming to overcome challenges related to material durability and system reliability [20].
