Dynamic Modeling and Experimental Study of Biomimetic Robotic Manta Ray

仿生机器蝠鲼独特的胸鳍摆动推进方式更适合风浪干扰环境下长航时水下作业需求,国内外已经开展了相关研究,但目前仿生机器蝠鲼研究中存在驱动能力弱、控制精度低、仿生效果差等问题。文中以蝠鲼为仿生原型,分析其生物学特性和运动机理,构建运动学模型和动力学模型,为仿生机器蝠鲼的系统设计提供了理论依据,设计了机械结构和控制系统,通过模拟波浪干扰环境下的直线前游、原地转弯和动态沉浮等试验,测试了仿生机器蝠鲼在复杂环境下的性能,验证了仿生机器蝠鲼的运动性能和应用前景。

The unique pectoral fin swinging propulsion method of biomimetic robotic manta ray is more suitable for long-term underwater operations in wind and wave environments.Relevant research has been conducted both in China and abroad,but there are problems in the current research on biomimetic robotic manta ray,such as weak driving ability,low control accuracy,and poor biomimetic effects.This article took the natural manta ray as a biomimetic prototype,analyzed its biological characteristics and motion mechanism,and constructed its kinematics and dynamics models,thus providing a theoretical basis for the system design of the biomimetic robotic manta ray.The mechanical structure and control system were also designed.The experiments of straight forward swimming,in situ turning,and dynamic sinking and floating were carried out under simulated wave environments to test the performance of the biomimetic robotic manta ray in complex environments,verifying the motion performance and application prospect of biomimetic robotic manta ray.
