Simply put, you create a file called robots.txt and put it in your home directory. The point of the file is to PREVENT robots accessing content. If you want them scanning your site completely you don't need a robots.txt.
However, your error log can get cluttered up with "robots.txt -- file not found" as the spiders keep checking for it, so it may be worth adding just to clean up your error logs.
