Well, consider the autobot as a program that types instead of you. You can "record" a script of keys and delays. So basically you can simulate a player or anything. That lets you spam servers (it can type extremely fast). It's also able to crack passwords.
You can experiment using notepad. Write a script and press F6 (I think). Make it repeat what you type 10 times and it will appear there 10 times without you even touching the keyboard.
