基于谐振运动原理的四足仿生机器人运动控制研究基于谐振运动原理的四足仿生机器人运动控制研究

摘要：

仿生机器人在近年来备受研究者们的关注，由于其具备的优异的生物学特性和动态平衡控制能力，在军事、医疗、救援、探测等领域都有着广泛的应用前景。然而，作为仿生机器人重要组成部分的运动控制机制研究仍然十分基础和尚未充分发掘。因此，本文基于谐振运动原理，开展了四足仿生机器人运动控制方面的研究。本文首先分析了四足仿生机器人的动力学模型，并设计了该运动控制系统的实验平台。在平台实验的基础上，本文发现了谐振运动原理在四足机器人运动控制中的重要性，根据此原理，本文设计并实现了一种利用Kevlar材料制作的新型带有绳索结构的主被动足部运动机构。通过实验验证，该运动机构能够大幅提高四足机器人的运动速度和稳定性。在此基础上，本文进一步提出了一种基于谐振运动原理的四足机器人运动控制策略，并通过仿真实验进行验证，取得了较好的控制效果。因此，本文所提出的基于谐振运动原理的四足仿生机器人运动控制方案可以为后续仿生机器人运动控制相关的研究提供有价值的参考。
