摘要
Armyo是用于經(jīng)橈動脈截肢的假手，通常稱為下肘或前臂截肢。使用Myo Armband，用戶可以通過設(shè)置四個手勢來控制此設(shè)備，其中每個手勢都指示一個功能。
該設(shè)備的功能分為4組，每組4個功能，總共16個。由于我們有4個功能的4個手勢，使用開關(guān)我們可以改變功能組但使用相同的手勢。此外，想要構(gòu)建此項目的設(shè)計人員可以通過更改代碼來設(shè)置用戶想要執(zhí)行的功能。
手還有另外兩個按鈕，一個用于阻止通信，使其所處的位置或功能固定，另一個用于打開和關(guān)閉背光。
LCD屏幕顯示有關(guān)手的組和位置的信息。
假肢的控制由Arduino Nano處理，它與Myo臂帶通信，拋出一個HM10藍牙模塊。

說明
Myo-Arduino通訊
您需要實現(xiàn)的第一件事是Myo-Arduino通信。我們使用本教程來完成它，所以你應(yīng)該這樣做。推薦的BT模塊是HM-10。
教程：

試試一些例子，確保你做對了！
硬件測試
接下來，您應(yīng)該對電子產(chǎn)品和配置進行測試。如圖所示連接組件并嘗試整個過程！
您應(yīng)該使用兩個電池輸出，2A用于帶USB母連接器的伺服電機，1A用于其余組件。您可以將此輸出連接到Arduino的USB端口
使用“ARMYO-Version_1.3.ino”文件對Arduino Nano進行編程。
要使用此版本，您應(yīng)該知道：
1）等到Myo和Arduino連接完畢。液晶顯示器將顯示“Armyo esperando ......”（Armyo等待）。
2）然后使用同步手勢，直到液晶顯示屏顯示該組。
3）為了使伺服器移動，你需要做兩個同心的手勢，一個用于選擇，一個用于確認（這是出于安全原因“。所以，如果你做出”波出“手勢并且Myo檢測到它會振動，液晶顯示屏會顯示機芯旁邊有三個懸掛點。這意味著你需要再次做手勢才能讓手移動。

原理圖
部件
1）打印每個部分！
對于前臂或背部前臂片，您應(yīng)該打印三個碎片（Asup1，Asup2和Asup3）以便于組裝。
2）將一些電纜焊接到FSR傳感器。確保它們足夠長。然后焊接母USB連接器的VCC和GND引腳。
3）制作PCB。注意尺寸，使它們適合手。
4）將舵機放在腹前臂并擰緊。
5）組裝手
您應(yīng)該使用Gael的教程進行手工裝配，因為它基本相同。

唯一的區(qū)別是你應(yīng)該用拇指，索引和中臂的弦引入FSR的線。琴弦和電線也應(yīng)穿過手腕的孔。
6）將母USB連接器放在背部前臂的空間中并粘貼三個部分。您可以使用任何塑料粘貼膠或氯仿。這個可能是有害的，所以在通風的地方使用它有保護！
7）將液晶顯示屏固定在背部前臂上。
8）把整個東西放在一起享受吧！

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!
