sitemap is an XML (structured data) file that tells google what pages are on your website to help google index and structure your page right. I suggest you install YOAST SEO Plugin (or some other sitemap plugin) in case you use wordpress for your site. In google webmaster tools (you should use webmastertools!) you can submit your site map, and google will tell you if there were any errors. Its really easy. Robots.txt is a file that is on every webhost, you can use it to set access restrictions. For example you could ban some sites, or users (like crawlers from semalt, mejasticseo, ahrefs etc.) from accessing your site or specific pages of your site. Generally, you dont need to change robots.txt, if you want to restrict access to your website, you should read more about robots.txt. If you dont want to restrict anything, you can leave it as it is. hope that helps
We create Sitemap to tell about all website pages to search engine. While Robots is set of instruction for spiders.
Sitemap is a list of pages that is access by the user. Google will index that page then the ranking result will come. Robots.txt is tag which is used inside the body which prevent the page for crawling or indexing.
Sitemaps help ensure your site is fully indexed by feeding your content to search engines. XML sitemap is standard. Robots is set of instruction for spiders.

1. Something you need for better indexing. Check Google next time. 2. It's robots.txt, not robo.txt or robot.txt I am really curious why don't you first write those words in Google or any other SE before starting new thread asking such questions...
