Roboko
Original Name: Roboro (ロボ子) / Yuriko (ユリ子) — 1973 only
English Name: Robyn (Amazon Kindle translation)
Roboko is a robot character and gadget that Doraemon brings back from the 22nd century. She's essentially a robotic female companion, designed with the kind of futuristic tech you'd expect from Doraemon's time period. The character was originally called Yuriko when she first appeared in 1973, though the name Roboko became standard afterward.
In English releases, particularly the Amazon Kindle translations, she goes by Robyn instead.
