All was unexpected. Likin, though, was temporary tax that the Qing Dynasty established for raising money to repress the taiping rebellion. It had been censured for seventy eight years. This showed that the existence of likin had its profound background of economy and society. Abolishing likin was to "change a little, then influence the whole", and it existed contradiction not only between China and other countries, but also between the center and the local authority. The problem of likin systems abolition was the problem about not only economy but also politics.

厘金虽然一开始是清王朝为筹措镇压太平天国运动军费而设立的临时税种，但其屡遭非议却长达78年的历史表明，厘金的存在有其深刻的经济与社会背景，"裁厘"可谓是"牵一发而动全身"，不仅存在着中国与各国列强之间的矛盾，而且存在着中央与地方政权之间的矛盾，厘金的裁撤问题，既是经济问题，又是政治问题。

Firstly, several kinds of schemes were proposed according to the design demand. The best scheme was chosen after analyzing and comparing the schemes. The robot's structure was designed with Pro/Engineer and AutoCAD software. Secondly, the kinematics analysis conducted, coordinate transformation matrix using D-H method was set up, and the kinematics equation direct solution and inverse solution was deduced. The manipulative interface about the kinematics equation direct solution and inverse solution was completed with VC++ and the velocity Jacobian of displacement matrix was constructed using differential transform method. In the process of the trajectory planning based on robot's kinematics analysis, I propone a method by which we can get middle nodal point with normalizing factor in order to simplify our searching for these middle nodal points. In addition, I give these middle nodal points with actual physics signification. For eliminating contradiction between real-time and accuracy, I bring forward separately limit of error and reversal interpolation method. For decreasing calculation quantity, we resort to tri-spline interpolation in the articulation space.We analyse the work range of the robot by resorting to graphic means.

首先，作者针对机器人的设计要求提出了多个方案，对其进行分析比较后，选择其中最优的方案后用Pro/Engineer和AutoCAD软件进行了机器人模型结构设计；其次，进行了运动学分析，用D-H方法建立了坐标变换矩阵，推算了运动方程的正、逆解，运用VC++制作了正、逆运动学求解的求解界面；并且用微分变换法推导了速度雅可比矩阵；在基于机器人的运动学的轨迹规划中，通过在操作空间的规划，提出了归一化因子来求解中间结点，通过它可以使求解中间结点变得更简单，并且赋予这些中间结点实际的物理含义，对于规划中精确性和实时性的矛盾，提出了以误差极限法和反向插值法来解决的方法；为了减少规划过程中计算量，在关节空间进行三次样条插值；然后借助图解法进行工作空间分析，作出了实际工作空间的轴剖图。
