Spider is a program that search engins used to download web pages.

Crawler is a program that automatically follows all your links on every webpages on your site.

And if you want to know about Robots then It is a program that automatically visit websites & perform predefined task like crawling task. It combines the tasks of crawler & spider together and help indexing and ranking of websites on search engines.

Spider is the program which is responsible for searching, downloading and store your site in search engine data base.
Crawler is the program that follows the content on your site, each time you edit, add new content or links etc, the crawler notify google about the changes for the ranking or other way round.

A program that automatically fetches Web pages. Spiders are used to feed pages to search engines. It's called a spider because it crawls over the Web. Another term for these programs is web crawler.
Crawling is the process performed by search engine crawler, when searching for relevant websites on the index. For instance,Google is constantly sending out "spiders" or "bots" which is a search engine's automatic navigator to discover which websites contain the most relevant information related to certain keywords.
