Even if entirely impractical, I have a special place in my heart for R.O.B. the Robot Operating Buddy. I knew people that had one yet it was so slow and clunky to use we didn't even try to play Gyromite with it. The Gaming Historian makes the case that Nintendo created R.O.B. to get into stores after the video game crash but that they might have been successful without it. It's hard to say ultimately what would have happened if they didn't create R.O.B. but there's not denying how big Robots were at the time and including one with the Nintendo was a huge attractor for young kids.
