Driven by bio-inspired propulsion mechanisms， bionic robotic fish exhibit high propulsion efficiency， superior maneuverability， and low navigation noise during underwater locomotion， enabling stable operation in complex aquatic environments. This provides new technical pathways for marine environmental monitoring， fishery resource surveys， and underwater engineering operations. This paper systematically reviews the research progress of AI-enabled soft bionic robotic fish from 2005 to 2024， summarizing key developments across core dimensions including biological prototype mechanisms， bionic design theories， structural and actuation approaches， intelligent control algorithms， and power supply systems. Comparative analyses are conducted based on propulsion modes， actuation types， and typical application scenarios.The results show that the BCF （Body and/or caudal fin） propulsion mode delivers superior efficiency for long-distance， high-speed cruising， while the MPF （Median and/or paired fin） propulsion mode offers enhanced stability for low-speed maneuvering and near-bottom precision operations. Significant breakthroughs have been achieved in artificial muscles and flexible actuation for low-noise， highly biomimetic locomotion， yet bottlenecks remain in cycle life， output consistency， and engineering costs. Phased progress has been made in multimodal perception， autonomous decision-making， and distributed cooperative control， yet cross-platform adaptability， performance in complex sea conditions， and reproducibility in real-sea trials remain insufficient.Future research should prioritize three core breakthrough directions： deep integration of artificial intelligence and intelligent control， development of novel smart materials， and expansion of cross-medium operational capabilities. Key priorities include establishing unified testing benchmarks， long-term sea trial verification systems， and standardized engineering design specifications to comprehensively enhance the engineering application level of soft bionic robotic fish in marine exploration， fishery resource surveys， and underwater operation scenarios.
