Question: I want to use selenium webdriver methods in the robot framework library. 

```
def custom_go_to
        driver = BuiltIn().get_library_instance('SeleniumLibrary')
        driver.go_to(url)

```

The above code from custom library works fine, but I want to use selenium method at the place of robotframework builtin library.
When I try to use **driver.get(url)** it says

```
'SeleniumLibrary' object has no attribute 'get'

```

The custom library I created ERP.py looks like

```
class ERP: 
   @keyword
    def custom_go_to(self, url):
        driver = BuiltIn().get_library_instance('SeleniumLibrary')
        driver.get(url)

```

And Test Case looks like

```
***Settings***
Library  SeleniumLibrary
Library  path_to_lib/ERP.py

*** Variable ***
${BROWSER}  |  chrome
${URL}  |  facebook.com

***Test Cases***
Open the browser using an inbuilt keyword and go to a given URL using custom go to using EventFiringWebDriver.
     Open Browser |  about:blank  |  ${BROWSER}
     Custom Go To  |   ${URL}

```

How can I use Selenium webdriver methods inside the robot framework library?

Answer: 
The selenium library itself is not a webdriver object, it's just an instance of the SeleniumLibrary class. You need to get a reference to the driver, which is an attribute in the library.

```
def custom_go_to(url):
    selib = BuiltIn().get_library_instance('SeleniumLibrary')
    selib.driver.get(url)

```

For more information about interacting with SeleniumLibrary at a low level, see the document [Extending SeleniumLibrary](https://github.com/robotframework/SeleniumLibrary/blob/master/docs/extending/extending.rst) in the SeleniumLibrary git repository.
'SeleniumLibrary' do not have get attribute. Please refer to [Selenium Library Robot Framework](http://robotframework.org/SeleniumLibrary/) for more info.

You should be using 

```
Open Browser    ${LOGIN URL}    ${BROWSER}
