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。

The results prove that using the laser power P=1.7Kw, scanning velocity V=4mm/s, spot diameter D=3mm, cladding thickness T=0.6mm, 50%: 50% Ni60:Ni-Cr-Cr_3C_2 as laser cladding process can obtain the laser coating with lubricous tight surface, tiny dilution rate ,fining microstructure and higher micro hardness and fine metallurgical-bonding Interface.

试验结果最终证明，激光熔覆工艺参数对熔覆层的宏观形貌、微观组织及涂层性能有极大的影响，在激光熔覆工艺参数为功率P=7Kw，速度Vs=5mm/S光斑直径D=3mm，厚度T=0.6mm，50%；50%的Ni60；Ni-Cr-Cr_3C_2的条件下，所得到熔覆层表面光滑致密、组织细小均匀、稀释率小、硬度高且与基体实现了良好的冶金结合，证明这种方法是一种在提高热锻模寿命方面有前途的方法。

The master processor finishes the A/D convertion and buffers the result data on it's RAM until 200 Bytes before it is writen into the dual-port RAM. When the data reached the flash's one page, the slave processor reads the data and sends it into the flash by page programming.

方案中，主单片机负责A/D转换并在片上RAM缓存数据，满200字节时打包写入双口RAM；当双口RAM缓冲区中的数据达到闪存的页容量时，由单片机读取数据，从单片机以页编程方式一次写入闪存。
