无惧高压低温极端环境，软体机器人挺进4070米深海

Core Insights - The research team from Harbin Engineering University has developed a new type of deep-sea soft robot that utilizes electro-hydraulic drive technology, enabling it to navigate extreme underwater environments effectively [1][2][5]. Group 1: Technology and Innovation - The deep-sea soft robot measures approximately 32 cm in length and 18 cm in wingspan, weighing only 670 grams, showcasing its lightweight design [1]. - The robot operates by converting electric field forces into driving forces through a flexible electro-hydraulic unit, which consists of a thin film shell, flexible electrodes, and a dielectric liquid [2][3]. - The team has addressed the challenges posed by high pressure and low temperature in deep-sea environments by integrating a "plasticization mechanism" that maintains the flexibility and deformation capabilities of the electro-hydraulic unit [3]. Group 2: Performance and Testing - The robot has been tested in various deep-sea locations, including the South China Sea, where it successfully completed complex trajectory movements and environmental sensing tasks at depths of up to 3176 meters [5][6]. - During trials, the robot demonstrated reliable maneuverability and perception capabilities in extreme pressure and complex flow conditions, confirming its operational effectiveness [5][6]. - The research team is exploring further integration of miniaturized components for driving, sensing, and communication, aiming to enhance the robot's capabilities for ecological observation and in-situ sampling [6].
