How can I set the trigger to make the robot check if there is a specific file in the folder and then start doing the algorithm?
If you want to make a sort of a time trigger then you will want to use the ‘File found?’ function. It checks if the file exists in the specified destination. If it exists then the ‘Yes’ branch is executed, if it doesn’t then the ‘No’ branch will be executed. It all means to you that you can create a loop where you would be checking if the file exists until it actually appeared in the folder. And the ‘Yes’ branch will contain actions that must be performed when the file appeared.
@Zoilaa, take a look at this link if you need more information about the function I proposed.

Your workflow will represent something like this:
