针对一种新型仿暗绿鲀机器人,以提高其机动性与优化外形为目的进行研究,设计具有双自由度胸鳍和二关节尾鳍的机器鱼.它的胸鳍对称地排列在两侧,可以做拍翼和摇翼两个自由度的运动,用于推进或其他目的,如转弯和潜水.最后,进行三组实验,研究机器鱼在三种不同推进模式下的游动性能,重点在于对胸尾鳍协同推进的研究.实验结果表明,尾鳍推进和胸鳍推进的游动速度与模型预测基本吻合.此外,单独使用尾鳍推进时,游速可达0.14 m/s;单独使用胸鳍推进时,游速可达 0.04 m/s;胸鳍和尾鳍协同推进转弯时,最大游速可达 0.19 m/s,最大转弯速度可达0.4 rad/s,此时转弯半径为0.15 m.
Design of a biomimetic robotic fish with coordinated propulsion of pectoral and caudal fins
In this paper,a robotic fish with a double-degree-of-freedom pectoral fin and a two-jointed caudal fin is described.Its pectoral fins are symmetrically arranged on both sides,and it can make two-degree-of-freedom motions of rowing and feathering for propulsion or other purposes such as turning and diving.Finally,three sets of experiments were conducted in this paper to investigate the swimming performance of the fish in two modes:2-degree-of-freedom pectoral fin propulsion and two-side pectoral fin and caudal fin synergistic propulsion.The experimental results show that the swimming speeds of caudal fin propulsion and pectoral fin propulsion are in general agreement with the model predictions.In addition,the swimming speed of the fish could reach 0.14 m/s when using caudal fin propulsion alone,and 0.04 m/s when using pectoral fin propulsion alone,and when the pectoral and caudal fins were used for coordinated propulsion to turn,the maximum swimming speed was up to 0.19 m/s,and the maximum turning speed was up to 0.4 rad/s,at which time the radius of turn was 0.15 m.
