 In this Taiwanese OAV series, we follow a cute (if rather dysfunctional and hyperactive) robot and his many adventures with his robot and children pals. Meanwhile, the diabolical megalomaniac robot inventor Horton the third (called Horus in the US version) wants to take advantage of Robby and Robby s inventor, Dr. Upper Decker, so he and his female cohorts, could have the world all to themselves. But it won t be so easy, since Robby, Upper-Decker and their pals have tricks of their own up their sleeves.
