论文摘要
我们已经开发了具有被动动态步行机制的圆锥形机器人。这项研究提出了一个指南针模型，其摇摆质量连接到上半身，并沿水平方向振荡，以阐明上身的水平动力学对两足动物行走的影响。该模型的极限周期进行了数值搜索，并研究了它们的稳定性和能源效率。根据支持摇摆质量的弹簧常数，获得了几个不同的极限周期。特定类型的解决方案降低了稳定性，同时降低了意外下降并提高能源效率的风险。获得的结果归因于摇摆的质量朝与上半身相反的方向移动，从而防止行走时加速和减速的大幅变化。研究了所提出的模型的运动与实际的双头机器人与人类步态之间的关系。
We have developed biped robots with a passive dynamic walking mechanism. This study proposes a compass model with a wobbling mass connected to the upper body and oscillating in the horizontal direction to clarify the influence of the horizontal dynamics of the upper body on bipedal walking. The limit cycles of the model were numerically searched, and their stability and energy efficiency was investigated. Several qualitatively different limit cycles were obtained depending mainly on the spring constant that supports the wobbling mass. Specific types of solutions decreased the stability while reducing the risk of accidental falling and improving the energy efficiency. The obtained results were attributed to the wobbling mass moving in the opposite direction to the upper body, thereby preventing large changes in acceleration and deceleration while walking. The relationship between the locomotion of the proposed model and the actual biped robot and human gaits was investigated.
