The main advantage is that this design is built for the LED use in our design, 主要的优点是，这种设计是建立在应用在我们的设计， so the efficiency is maxim. But there are several disadvantages; the first one is that 因此效率是格言。但也有一些缺点；第一个是 this project is an academic one, so it’s interesting try to design a module like this. The 这个项目是一个学术，所以这是有趣的尝试设计一个这样的模块。本 second one is referral to the transmitter emplacement; in the robot we can’t have 32 V 另一种是转介到发射位置；在机器人不能有32伏 for input voltage and the input voltage minimum is so high. Without these limits the 输入电压和输入电压最小值太高。如果没有这些限制 most efficient and appropriate is use this module. 最有效的和适当的是使用此模块。 The other possibility is design a driver . One possibility is using a MOSTET2. 另一种可能性是一个驱动程序设计。一种可能性是使用mostet2。 Other type is driven using a moderate power FET 13(field effect transistor) and 其他类型的驱动使用中等功率场效应晶体管（场效应晶体管）和13 appropriate logic. Its possible drive by a high speed MOS transistor with low input 适当的逻辑。其驱动的高速晶体管具有低输入 capacitance in order to achieve sharp turn-on edges that can be easily detected by the 电容以达到尖锐的导通的边缘可以很容易地发现的 receiver. 接收机。 All these drive system are right for a general optical communication, without 所有这些驱动系统适合一般光通信，无 limit of external current input. Our problem is again the transmitter emplacement 外部输入电流限制。我们的问题是再发射位置 where we have power limit. For these reason we decided use an hex inverters array, 我们在那里有功率限制。由于这些原因，我们决定使用一个十六进制逆变器阵列， exactly the MM74HC04. 完全mm74hc04。

1) Wear safety shoes and clothes appropriate for safe operation. Take caution to avoid getting clothes or hair caught in the machine.穿着有利于安全操作的鞋子和衣服。注意不要让设备绞住衣服和头发 2) Use the rated power supply indicated on the machine.使用设备上标注的额定电压（工作） 3) Never touch rotating parts while the machine is running. Make sure the machine has come to a full stop before changing the polishing fixture.设备运行时不要触碰运转中的零件。替换抛光夹具前确认设备已经完全停转 4) To prevent rusting, immediately wipe the unit dry after you turn off the power. 为了防止生锈，切断电源后立即将部件拭干 5) Never use or store the machine in very humid environment. 不要在特别潮湿的环境里操作或者存放设备 个人见解，望探讨
