Abstract
The undulating fin propulsion is inspired by fish using Median and/or Paired Fin (MPF) mode. This mode provides advantages of the vector thrust production and small disturbance to the ambient flow field, and also it could be applied on underwater robots conveniently. Two bionic undulating fins are designed to imitate the structure and function of undulating fin of aquatic animals, which are fixed-waveform mode and independently-driven mode. The active deformation of bionic undulating fins is described by a kinematic model. Base on the kinematic model, a simplified computational model is derived theoretically to analyse the dynamics of the bionic propulsor. The dynamic model considers six components of forces and moments. The dynamics performance related to the geometric parameters, undulating parameters as well as the carrier velocity are further discussed through simulation. Furthermore, the above analytic method is verified through the thrust/moment and velocity test using the bionic propulsor.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
