Yeah, ROB was made in Japan, by Nintendo. Definitely a 1st party accessory, like the Zapper (though it looked a LOT different in Japan), but unlike the Power Glove. Heck, look at Smash Bros. It wouldn't be in the game as a playable character if it was US-only, and one of the costumes is ROB's Japanese color scheme (red and white, like the Famicom).
"On two occasions, I have been asked [by members of Parliament], 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able to rightly apprehend the kind of confusion of ideas that could provoke such a question." ~ Charles Babbage (1791-1871)
