31. Kiteretsu Daihyakka

Another Fujiko Fujio series (this one being the creation of Fujiko F. Fujio), Kiteretsu Daihyakka is the story of Kiteretsu, a schoolboy inventor and his self-built robot friend, Korosuke. The manga was created in the mid-70s, but the anime started in 1988 and ran for 8 years. There was also a live action special made in 2002.

And that's about all you can find out about the show in English.

In fact outside of Doraemon, Fujiko Fujio's works are somewhat ignored in the anglosphere, Fujiko Fujio (A)'s work especially. The only time I've encountered it I think was the BBC showing some subtitled episodes of The Laughing Salesman in 1998.
