TL;DR
Rename Personal Roboport in the English locale to Portable RoboportWhy?
"Personal Roboport" brings forth concepts like "customized, unique to the user, one-of-a-kind;" and "singular ownership, not shared between multiple people or multiple places." But Personal Roboports aren't just used by the player character, they are also used by spidertrons and tanks. Also, there are mods that add custom vehicles with equipment grids, and mods that add equipment grids to locomotives. The Personal Roboport item is not unique to a single vehicle nor to the player character themself."Portable Roboport" is a more accurate description. It is literally a piece of machinery (equipment) that is easy to transport (portable). I'll make a comparison: A diesel generator that is designed for easy transport by hand, or by vehicle, is known as a portable generator. If one were to call it a personal generator in conversation, that would spark confusion.
I almost wonder if "Personal Roboport" was a bad translation from long ago. Or perhaps just a brain fart, when somebody couldn't quite remember the word they were looking for.
