During the early 1980s, Namco wasn't only conquering arcades with games like Pac-Man. The company was doing something else. Something important. It was building robots.
Ash wasn't on hand when I stumbled on this video showing a robot Mappy navigating a cheese-less maze at the Namco Bandai HQ, so I have no clue what this is about. But I do know that it's a robot that looks like Mappy, and it's in a maze. There's also a bit of Goro getting ready to run the maze. Odd.
