How to apply If, Else condition in RobotFramework with SikuliLibrary? by using those two image on RIDE.

One answer here, but it's not exactly answer of my question.

Answer 1

There is an Exists keyword that will tell you if an image exists on screen. This results in a true/false response that can be used by the Run Keyword If keyword:

*** Settings ***
Library    SikuliLibrary

*** Test Cases ***
TC
    ${exists}    Exists    ./some_image.png
    Run Keyword If    "${exists}"=="true"    Run True Keyword
    ...    ELSE IF    "${exists}"=="false"   Run False Keyword
    ...    ELSE                              Run Error Keyword   

This may be implemented as a seperate keyword which will click on the image if exists and otherwise ignores.

*** Settings ***
Library    SikuliLibrary

*** Test Cases ***
TC
    # Check if button exist and retry for 2 seconds returning false.
    Click If Exists    ./ok_btn_dialog.png    ${2}
    Click             ./login_screen.png

*** Keywords ***
Click If Exists
    [Arguments]    ${image}    ${timeout}=${0}
    ${exists}    Exists    ${image}    ${timeout}
    Run Keyword If    "${exists}"=="true"    Click  ${image}
