Blatherbot

Blatherbot is a Robot of apparent British origin. He is one of the oldest living members of the League of Robots, and despite never having the title of ruling the League, he holds permanent position and is well respected by the rest of the members, who are quite willing to listen to him blather on about whatever.

Trivia

 * While he is never referred to by any name in the film nor the commentary, due to his apparent only functionality, that of blathering, it would seem likely that this would be his name. But, as one would gather, this name was purely decided by The Infosphere in our Infinite Wisdom - however, it was subsequently canonised with the character's inclusion in mobile game Worlds of Tomorrow.
