        ${download directory}    Join Path    ${OUTPUT DIR}    downloads_${now}
        Create Directory    ${download directory}
        ${chrome options}=    Evaluate    sys.modules['selenium.webdriver'].ChromeOptions()    sys, selenium.webdriver

I have quite simple workaround for file downloads. It has following rules:

Create download folder in suite setup

Set Global Variable    ${global_downloadDir}    ${CURDIR}\\Downloads\\${suite_orgName}
${chromeOptions}=    Evaluate    sys.modules['selenium.webdriver'].ChromeOptions()    sys, selenium.webdriver
${prefs} =    Create Dictionary    download.default_directory=${global_downloadDir}
Call Method    ${chromeOptions}    add_experimental_option    prefs    ${prefs}
Create Webdriver    Chrome    chrome_options=${chromeOptions}

Clear the folder on test teardown
```
Run Keyword And Ignore Error    Empty Directory    ${global_downloadDir}
```
With above, you'll be easily able to manipulate downloaded files.

Although above answer is good but for me following code worked.

Conference Summary
     ${output}=   Run keyword   SLO conformance summary
    # create unique folder in current directory
    ${current_date}=    Get Current Date 
    ${folder_name} =    Convert Date    ${current_date}    result_format=${SUITE NAME}.%d.%m.%Y_%H.%M
    ${download directory}    Join Path    ${OUTPUT DIR}    ${folder_name}
    Create Directory    ${download directory}
    ${options}  Evaluate  sys.modules['selenium.webdriver'].ChromeOptions()  sys, selenium.webdriver
    Call Method  ${options}  add_argument  --start-maximized
    ${preferences} =    Create Dictionary   prompt_for_download=false  download.default_directory=${download directory}    download.directory_update=True
    Call Method  ${options}  add_experimental_option  prefs  ${preferences}
     Create WebDriver  Chrome  chrome_options=${options} 
    Go To    ${output}     
    sleep   4
    Page Should Not Contain Element  //div[@class='errorIcon']
    Run Keyword     Get export position
