摘要

提出了一种具有三个自由关节的行走机器人的数学模型。将机器人作为变因果动态系统(VCDS)进行系统研究,确定了机器人的数学模型。考虑到可能的对称结构,只考虑垂直的xz平面演化。结果可以推广到三维空间。该方法最适合于可变动态系统,因为这对的每条腿都可以根据因果顺序改变状态。认为第一腿两个关节都是自由的,第二腿第二个关节是自由的。在MATLAB环境下实现了该模型,并给出了一些演化实例。

Control Strategy of a 3-DOF Walking Robot
The paper presents the mathematical model of a walking robot where the active pair of legs has three free joints. The mathematical model of the robot is determined considering a systemic approach of the robot as variable causality dynamic systems (VCDS). Taking into account a possible symmetrical structure, only the vertical xz-plane evolution is considered. The results can be extended to three-dimensional space. The approach is best on variable dynamic systems, considering that each leg of the pair can change the state depending of the causality order. It is considered that the first leg has both joints free and the second leg has the second joint free. The model is implemented in MATLAB environment and some evolutions examples are presented.
