Bender Bending Rodríguez's mother is a minor character. Bender Bending Rodríguez told his son Ben that he inherited his arm control software from her. She can't talk and is, apparently, a religious fundamentalist, and never taught Bender about Robot reproduction, thus, she became nervous when Bender's significant other (only for one moment), Bev gave birth to his son Ben Rodríguez in 3012.
She is also part of the storyline in the Radiorama podcast special episode.
