Long long ago , i promise to produce a joystick for you , but i failed again and again . cause i am stranger in chengdu , it is too difficult to search some materials which the joystick need . but now , i beat all the difficulties , and i can do it , and send some pictures to you 很久以前,我就答应要给你做个摇杆,但是我一次又一次地失败了.主要是因为我在成都是个陌生人,有些摇杆需要的材料特别难找,但是现在,我还是解决了所有问题,我现在可以做摇杆了,现在把其中一个成品的照片发到这里来给你看一下
The tradtional interface requires the user to press many keys or conditional functionality with the accessing screen . " matrix mapping system " on the other hand requires only a few keystrokes or movements of the joystick for a large number of functions to be accessed without requiring any precise cursor movements 传统的选单表，需要使用者一面看着萤幕一面按下很多键，相反地， “全方位搜索系统”的大量功能，只需按下很少键或稍微移动游戏杆，而无需仔细调校光标位置。
After the hardware and software of the contro1 system of the experiment system have been finished , an experiment is done on the basis of the experiment system . the resu1t of the experiment shows that the underwater manipu1ator can be contro11ed under the contro1 ways of joystick and 1oca1 area network , and can finished the required work missions in the two contro1 ways 研制完成了水下机械手控制系统的硬件和软件系统，并对系统进行了实验调试，结果表明操纵杆和局域网两种控制方式均能实现对水下作业机械手的遥操作，可完成机械手相应的作业任务。
This article presents two control methods , which have already been realized in our micromanipulation system after we investigate all kinds of international advanced control technologies on micromanipulation , and combines our micromanipulation system characteristics . one method is that using joysticks controls the displacement in three - dimensional way based on the visual feedback , the other is that using pid control theory realizes the automatic displacement based on the raster sensors 本文在研究国际上应用在微操作系统各种先进控制技术的基础上，结合我们的微操作系统的自身特点，利用操纵杆实现基于视觉反馈的微操作控制和利用光栅传感器组成闭环系统实现基于pid控制原理自动定位。
