Update robot codes with latest directives

Changes:
   - Non local variable is not uppercase
   - The assignment sign is not consistent within the file.
     Expected = but instead of blank spaces
   - Run KeyWord If is deprecated since Robot
     Framework version 5.*, use 'IF' instead

Tested:
    - Checked using robot dry-run to make sure the
      syntax is not broken
