\n\tAbstract\uff1aWe used the immersed boundary-lattice Boltzmann method (IB-LBM) to establish a two-dimensional autonomous locomotion control bionic tadpole model. The tadpole is established by connecting a passive elliptical head with a beating tail. It can control the tail swing amplitude to change the swimming speed and achieve the desired swimming direction by attaching an angle offset on the tail axis. Based on the proposed tadpole swimming model, we studied its hydrodynamics in the swimming process by changing the confined space's width. And three points can be summarized as follows. First, in a specific width scope, the same swimming pattern will produce a lower swimming speed in a narrower channel. Second, a slight swing strength causes a small-scale disturbance to the surrounding fluid and will generate a small swimming speed. Third, a relatively small or excessive swimming speed is not conducive to the stability of its swimming. In addition, we further developed a perception-response strategy for the tadpole to achieve its autonomous locomotion control. A virtual perceptive field is proposed as the visual range, which helps to implement tadpole motion control with a set of mechanical response rules. With these improvements, the tadpole can effectively implement obstacle avoidance in complex obstacle array environments and track sine curve routines. Therefore, our study is significant in providing a reference for the theoretical design of some underwater bionic tadpole-like robots.\n<\/p>\n
