摘要
Armyo是用于经桡动脉截肢的假手，通常称为下肘或前臂截肢。使用Myo Armband，用户可以通过设置四个手势来控制此设备，其中每个手势都指示一个功能。
该设备的功能分为4组，每组4个功能，总共16个。由于我们有4个功能的4个手势，使用开关我们可以改变功能组但使用相同的手势。此外，想要构建此项目的设计人员可以通过更改代码来设置用户想要执行的功能。
手还有另外两个按钮，一个用于阻止通信，使其所处的位置或功能固定，另一个用于打开和关闭背光。
LCD屏幕显示有关手的组和位置的信息。
假肢的控制由Arduino Nano处理，它与Myo臂带通信，抛出一个HM10蓝牙模块。

说明
Myo-Arduino通讯
您需要实现的第一件事是Myo-Arduino通信。我们使用本教程来完成它，所以你应该这样做。推荐的BT模块是HM-10。
教程：
https://github.com/vroland/MyoBr ... -MyoBridge-Firmware
试试一些例子，确保你做对了！
硬件测试
接下来，您应该对电子产品和配置进行测试。如图所示连接组件并尝试整个过程！
您应该使用两个电池输出，2A用于带USB母连接器的伺服电机，1A用于其余组件。您可以将此输出连接到Arduino的USB端口
使用“ARMYO-Version_1.3.ino”文件对Arduino Nano进行编程。
要使用此版本，您应该知道：
1）等到Myo和Arduino连接完毕。液晶显示器将显示“Armyo esperando ......”（Armyo等待）。
2）然后使用同步手势，直到液晶显示屏显示该组。
3）为了使伺服器移动，你需要做两个同心的手势，一个用于选择，一个用于确认（这是出于安全原因“。所以，如果你做出”波出“手势并且Myo检测到它会振动，液晶显示屏会显示机芯旁边有三个悬挂点。这意味着你需要再次做手势才能让手移动。

原理图
部件
1）打印每个部分！
对于前臂或背部前臂片，您应该打印三个碎片（Asup1，Asup2和Asup3）以便于组装。
2）将一些电缆焊接到FSR传感器。确保它们足够长。然后焊接母USB连接器的VCC和GND引脚。
3）制作PCB。注意尺寸，使它们适合手。
4）将舵机放在腹前臂并拧紧。
5）组装手
您应该使用Gael的教程进行手工装配，因为它基本相同。

唯一的区别是你应该用拇指，索引和中臂的弦引入FSR的线。琴弦和电线也应穿过手腕的孔。
6）将母USB连接器放在背部前臂的空间中并粘贴三个部分。您可以使用任何塑料粘贴胶或氯仿。这个可能是有害的，所以在通风的地方使用它有保护！
7）将液晶显示屏固定在背部前臂上。
8）把整个东西放在一起享受吧！

Summary
Armyo is a prosthetic hand indicated for trans-radial amputation, commonly referred to as below-elbow or forearm amputation. Using the Myo Armband, the user can control this device by setting four gestures, where each one is indicated to a function.
The functions of this device are organized in 4 groups of 4 functions each one, indicating a total of 16. As we have 4 gestures for 4 functions, with the use of a switch we can change the group of functions but using the same gestures. In addition, the designer that wants to build this project can set the functions that the user wants to do by changing the code.
The hand also has two other buttons, one to block the communication so that the position or function it is in is fixed, and another to turn on and off the backlight.
The LCD screen shows information about the group and position the hand is in.
The control of the prosthetic is handled by an Arduino Nano which it is communicated with Myo armband throw a HM10 bluetooth module.

Instructions
Myo-Arduino Communication
The first thing you need to achieve is Myo-Arduino communication. We used this tutorial to do it and so should you. The recommended BT module is HM-10 .
Tutorial:
https://github.com/vroland/MyoBr ... -MyoBridge-Firmware
Try out some of the examples to make sure you got it right!
Hardware Testing
Next you should give a test to electronics and conifgurations. Connect the components as the image shows and try the whole thing!
You should use both batteries outputs, the 2A one for the servomotors with the USB female connector and the 1A one for the rest of the components. You can connect this output to the Arduino’s USB port
Program the Arduino Nano with the "ARMYO-Version_1.3.ino" file.
To use this version, you should know:
1) Wait until the Myo and Arduino are connected. The LCD will state "Armyo esperando..." (Armyo waiting).
2) Then make the sync Gesture to use until the LCD shows the group.
3) To make a the servos move, you'll need to make two identic gestures, one to select and one to confirm (this was done for safety reasons". So, if you make the "Wave out" gesture and the Myo detects it, it will vibrate and the LCD will show the movement asigned with three suspensive dots next to it. This means you need to make the gesture again for the hand to move.

Schematics
Assembly
1) Print every part!
For the supierior or dorsal forearm piece, you should print the three broken down pieces (Asup1, Asup2 and Asup3) for easier assembly.
2) Solder some cables to FSR sensors. Make sure they are long enough. Then solder the VCC and GND pins of the female USB connector.
3) Make the PCB's. Mind the sizes so that they fit in the hand.
4) Place the servos in the Ventral Forearm and screw them.
5) Assemble the hand
You should use Gael's tutorial for the hand assembly, as it is basically the same.
http://www.inmoov.fr/hand-and-forarm/
The only difference is that you should introduce the FSR's wires with the thumb, index and middlearm's strings. The strings and wires should also go through the Wrist's holes.
6) Place the female USB connector in the space in the Dorsal Forearm and glue the three parts. You can use any plastic pasting glue or chloroform. This one can be harmful so use it in a ventilated area with protection!
7) Fix the LCD screen to the Dorsal Forearm.
8) Put the whole thing together and enjoy!
