In this paper, we aim to study the swimming performance of fish robots by using a statistical approach. A fish robot employing a carangiform swimming mode had been used as an experimental platform for the performance study. The experiments conducted aim to investigate the effect of various design parameters on the thrust capability of the fish robot with a flexible caudal fin. The controllable parameters associated with the fin include frequency, amplitude of oscillation, aspect ratio and the rigidity of the caudal fin. The significance of these parameters was determined in the first set of experiments by using a statistical approach. A more detailed parametric experimental study was then conducted with only those significant parameters. As a result, the parametric study could be completed with a reduced number of experiments and time spent. With the obtained experimental result, we were able to understand the relationship between various parameters and a possible adjustment of parameters to obtain a higher thrust. The proposed statistical method for experimentation provides an objective and thorough analysis of the effects of individual or combinations of parameters on the swimming performance. Such an efficient experimental design helps to optimize the process and determine factors that influence variability.
在本文中，我们旨在通过统计方法研究机器鱼的游动性能。使用一种采用仿鱼游动模式的机器鱼作为实验平台，对性能进行研究。实验旨在研究各种设计参数对具有柔性尾鳍的机器鱼的推力性能的影响。与鱼鳍相关的可控参数包括频率、摆动幅度、展弦比和尾鳍的刚性。在第一组实验中，使用统计方法确定了这些参数的重要性。然后，仅对那些显著的参数进行了更详细的参数实验研究。结果，减少了实验次数和时间，完成了参数研究。通过获得的实验结果，我们能够了解各个参数之间的关系，并可以调整参数以获得更高的推力。所提出的用于实验的统计方法为个体或参数组合对游动性能的影响提供了客观而全面的分析。这种高效的实验设计有助于优化过程并确定影响变异性的因素。
