摘要
对由三个四面体和一个八面体并联组成的新型变几何桁架机器人机构 ,进行了结构分析和位置分析 ,并利用导出法推导出机器人手部的速度显式解析解。结果表明 ,这种机构在机器人运动学分析中具有计算简单、计算精度高的特点 。
Structure and position analysis is carried out for a novel type of variable geometry truss robot manipulator mechanism which is constructed in parallel by three tetrahedrons and an octahedron. The closed form solutions for the velocity and acceleration of the robot manipulator are obtained by using analytical method. The results show that this novel mechanism has the characteristics of simple calculation and high accuracy in its kinematic analysis, therefore, it can satisfy the requirements of real time control of the manipulator mechanism.
