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.


.. code-block:: python

    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>

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 (\OpenRPA\Resources\WPy32-3720\python-3.7.2)
- Execute in python x64 (\OpenRPA\Resources\WPy64-3720\python-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:

.. code-block:: python

    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:

.. code-block:: python

    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:

.. code-block:: python

    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)
