A spider is a program run by a search engine to build a summary of a website’s content (content index). Spiders create a text-based summary of content and an address (URL) for each webpage.

Spiders is a name for the robots or crawlers that scan web and save the information in websites to a database. Hence, "Google spiders" is another name for "Google indexing bots".

Robots - An automated computer program that visit websites & perform predefined task. They are guided by search engine algorithms & are able to perform different tasks instead of just one crawling task. They can combine the tasks of crawler & spider together and help in indexing and ranking of websites on any particular search engine.
