In addition to what has already been said and linked to, what exactly are you wanting to do with the bot?

While there are many complicated "bots" which already exist and can do a range of things, at the heart of it, all a bot is is "an automated process".

The bot flag exists to hide mass-automated edits from Special:Recent_Changes, but is not actually required in order to make automated edits.

Depending on what you want to do, there are several scripts on http://dev.wikia.com which can be used to do batch edits from your normal account.
