The Squires Curve of Description the Kinematic Trajectory of Thumb Needle

描述了建立手臂运动的模型。在此基础上 ,导出了拇指尖运动轨迹的Squires曲线。最后 。

In this article, the arm kinetic model was built up. At this foundation the Squires curve for the kinematic trajectory of thumb tip was derived.Based on mathematical software MathCAD, this curve was drawn and the motion picture of arm was formed at last.
