## Summary

FishSim uses a single motor, two crossed elastic tendons, and a five-coefficient stateless fluid model to make biomimetic robotic fish propulsion an identifiable pipeline. The paper presents a comparison of simulated and real swimming speeds at eight frequencies; trajectory error fell from 592 mm to 91 mm after identification, and it discusses coefficient sensitivity and the limits of the turning experiments.
