It was a simple enough mistake.

Anyone could have made it, really. The new Mindstorms Robotics Invention kit has been in the wild for a few weeks now: a new paradigm for LEGO Mindstorms, and I am curious to take a look at it sometime soon. Set 51515 is set to replace the 31313 EV3 as the LEGO Robotics set of choice at some point. Probably when the EV3 enthusiasts have all moved on to using Arduino…

But this wasn’t the problem I found myself with. So… when I was asked if I wanted any LEGO picked up, while a friend was out shopping,, I had a failing in my internal logic. I remembered that the third generation of Mindstorms, EV3 was set 31313. I also remembered thing that the new set followed a similar pattern, and it was the fourth generation.

And so I asked that if set 41414 could be picked up, that I would be grateful.
