摘要
以一个简单的双自由度compass-like无动力双足行走机器人为研究对象,对其行走的动态过程进行了深入分析。建立了行走动态的数学模型,并进行了数值仿真,对其行走过程每个阶段的特征进行了论述。分析了机器人行走过程中动能、势能的分布、变化过程以及相互转化关系。机器人稳定行走周期步态在相平面内表现为极限环,讨论了其存在的条件。
Focus on the study of a simple compass-like planar biped robot, the dynamics of the biped locomotion was analyzed. A mathematical model of this biped robot was presented with numerical simulations. The dynamics and its characteristics in every stage of the biped locomotion cycle were discussed, such as kinetic energy and potential energy distribution and evolvement of the robot. It seems that dynamics of symmetric gait of the robot appeared to be a limit cycle in the phase space. Furthermore, the condition for the existence of stable limit cycle was discussed.
