The invention relates to the technical field of underwater robots, and provides a variable-stiffness bionic tail fin based on a low-melting-point thermoplastic material and an underwater robot, the variable-stiffness bionic tail fin based on the low-melting-point thermoplastic material comprises a tail fin plate, a tail fin skeleton, a tail fin shell and a temperature control assembly; the tail fin framework is arranged on at least one side of the tail fin plate, and the tail fin framework is made of a low-melting-point thermoplastic material; the temperature control assembly comprises a heating piece and a temperature control piece, the heating piece is arranged on the tail fin framework, and the temperature control piece controls the heating temperature of the heating piece so as to adjust the rigidity of the tail fin framework; the tail fin shell covers the periphery of the tail fin plate. By means of non-uniform rigidity distribution and multi-rigidity change of the variable-rigidity bionic tail fin based on the low-melting-point thermoplastic material, the swimming performance of a bionic robotic fish under various environment conditions is expected to be improved and optimized, and the variable-rigidity bionic tail fin has high reliability and practicability.

    本发明涉及水下机器人技术领域,提供一种基于低熔点热塑材料的变刚度仿生尾鳍及水下机器人,上述基于低熔点热塑材料的变刚度仿生尾鳍,包括:尾鳍板、尾鳍骨架、尾鳍外壳以及温控组件;所述尾鳍骨架设于所述尾鳍板的至少一侧,所述尾鳍骨架采用低熔点热塑材料制成;所述温控组件包括加热件和温控件,所述加热件设于所述尾鳍骨架,所述温控件控制所述加热件的发热温度以调节所述尾鳍骨架的刚度;所述尾鳍外壳包覆于所述尾鳍板外周。利用该基于低熔点热塑材料的变刚度仿生尾鳍的非均匀刚度分布及多刚度变化,有望对仿生机器鱼在多种环境条件下的游动性能有所提升及优化,具有较强的可靠性与实用性。
