## About

The Robot tool is the main module for production process automation. It has no graphic/console interface. All low-level actions to OS are perfoming by the Robot tool in OpenRPA.

## Way to use

You can use the robot by the several ways:


* In Python script


* In Studio script (n/a)

### Create python script

In order to use robot just add Robot tool folder in work directory and add line “import GUI” in your script.

```
import sys
sys.path.append('../../')
import selenium # [Web app access](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.1.-Theory-&-practice:-Web-app-access-(Chrome,-Firefox,-Opera))<br>
import GUI  # [Win32 & UI Automation access](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.2.-Theory-&-practice:-Desktop-app-UI-access-(win32-and-UI-automation-dlls)) <br>
import pyautogui #[Screen capture/recognition](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.4.-Theory-&-practice:-Screen-capture-&-image-recognition) [#Mouse manipulation](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.3.-Theory-&-practice:-Keyboard-&-mouse-manipulation)<br>
import cv2 # [Computer vision](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.4.-Theory-&-practice:-Screen-capture-&-image-recognition)<br>
import keyboard #[Keyboard manipulation](https://gitlab.com/UnicodeLabs/OpenRPA/wikis/05.3.-Theory-&-practice:-Keyboard-&-mouse-manipulation)<br>
```

## Execute python script

The OpenRPA is fully portable solution. It contains own python enviroment both 32 and 64 bit versions. So, you can execute your python script in several ways:
- Execute in python x32 (OpenRPAResourcesWPy32-3720python-3.7.2)
- Execute in python x64 (OpenRPAResourcesWPy64-3720python-3.7.2.amd64)
- Execute from .cmd file

### Execute in the Python x32

To execute your python script in x32 bit version just write in command line from x32 python directory:

```
cd "\OpenRPA\Resources\WPy32-3720\python-3.7.2"
python.exe "path to your python script.py"
```

### Execute in the Python x64

To execute your python script in x32 bit version just write in command line from x32 python directory:

```
cd "\OpenRPA\Resources\WPy64-3720\python-3.7.2.amd64"
python.exe "path to your python script.py"
```

### Execute from .cmd file

In order to simplify the execution process you can write several code lines in file with the .cmd extension:

```
cd %~dp0
copy /Y ..\Resources\WPy32-3720\python-3.7.2\python.exe ..\Resources\WPy32-3720\python-3.7.2\OpenRPAOrchestrator.exe
.\..\Resources\WPy32-3720\python-3.7.2\OpenRPAOrchestrator.exe orchestratorMain.py
pause >nul
```

## Use in studio script (n/a)

```
import sys
sys.path.append('../../')
import GUI
import keyboard
import subprocess
import time

#Highlight the UI Object in Folder explorer<br>
GUI.UIOSelector_FocusHighlight([{"class_name":"CabinetWClass","backend":"uia"},{"ctrl_index":2},{"ctrl_index":0},{"ctrl_index":2},{"ctrl_index":0}])<br>

#Wait 2 seconds<br>
time.sleep(3)<br>

#Loop: get child element of UI List<br>
for lItem in GUI.UIOSelector_Get_UIO([{"class_name":"CabinetWClass","backend":"uia"},{"ctrl_index":2},{"ctrl_index":0},{"ctrl_index":2},{"ctrl_index":0}]).children():<br>
  &nbsp; &nbsp; &nbsp; &nbsp; print(str(lItem))
```
