In 2365, Robinson held the rank of lieutenant and served as a transporter chief aboard the Federation starship USS Enterprise-D, under Captain Jean-Luc Picard. She beamed Thadiun Okona aboard when his vessel, the Erstwhile, was disabled.
The script for "The Outrageous Okona" describes the character as "the very feminine and graciously endowed Transporter Commander B.G. Robinson. Everything she has two of are perfectly matched, coordinated, and move with a wonderful grace that is called 'woman.'" It goes onto say she always displays a "very professional manner." 
Due to much of her scenes being cut from the final version of "The Outrageous Okona", Hatcher asked that her name not be listed in the episode's credits. As such, she received no on-screen credit for her performance.
