The term Bots in League of Legends refers to computer controlled opponent (AI - Artificial Intelligence) available in custom games and Co-op vs. AI matches. Bots can have either "intro", "beginner" or "intermediate" AI.
On January 24, 2012, it was announced that the bot system would be expanded with more bots, better intelligence and availability on the Crystal Scar. On February 1, 2012, the system was released.[1]
On April 15, 2014, an update to the bot AI was released, primarily improving threat evaluation and the ability to dodge skillshots, as well as updating the item builds used.[2]
In V6.3 and V6.4 Riot added more bots to the bot roster. [3]
