针对MOTOMAN-HP20的示教编程、离线编程及远程控制方法进行了研究：以机器人夹持水杯倒水为例说明了机器人的示教编程方法；并以控制MOTOMAN-HP20机器人对12个堆放整齐的矩形零件进行搬运为例，通过远程控制软件MOTOCOM32实现机器人控制柜NX100与计算机之间的通信，从而操控机器人码垛；提出了现有机器人离线编程软件存在的不足之处。 最后，以LabVIEW为基础平台，设计、开发了一种新的离线编程软件，可以实现HP20多关节机器人的运动学正解与逆解运算，可完成空间任意两个约束点之间的直线插补和空间任意三个约束点间的圆弧插补。对于空间任意已知解析式的自由曲线能够较好地实现离线编程；对于二维平面内的任意未知曲线，该软件可以通过数据库中存储的各约束点的位姿，采用不同方法进行插值，并比较选出精度最高的差值方式，编辑、生成程序文件。软件的各部分功能均通过相应的实验进行了验证，能够操控机器人按照预期的轨迹进行运动。

线程同步机制。 互斥器的功能和临界区域很相似。区别是：Mutex所花费的时间比Critical Section多的多，但是Mutex是核心对象(Event、Semaphore也是)，可以跨进程使用，而且等待一个被锁住的Mutex可以设定TIMEOUT，不会像Critical Section那样无法得知临界区域的情况，而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.

进程调度主要是操作系统中用于模仿操作的进程的-The process of scheduling the operating system is mainly used to mimic the operation of the process

这是实现操作系统交通灯调度问题，里面不是很好，希望大家提出宝贵的意见-This is the realization of operating system scheduling problem of traffic lights, which is not very good, hope that the valuable advice
