Don't submit your robots.txt file -- It is not the kind of file they expect, and it won't do any good.
The best way to "submit" is simply to get links from other sites that are currently in the search engine index that point to your site. Their spider will follow those links to your site, and then follow the internal links on your site to find all of your pages, except those disallowed in robots.txt.
If you go to the search engines' "submit your site" pages and enter the URL of your home page, that *may* get the process started, but if your site lacks incoming links then the results will probably be short-lived. So the best approach is to get incoming links to your site from well-ranked and related-topic sites and from major directories, and just let the search engine spiders follow those links to find your site. "Site Submission" as practiced back in the 90's is dead, and you'll note that the Search Engine Submission forum here on WebmasterWorld is now deprecated.
