2012年7月6日 · Usually, though, the different colours are shown in the exact pattern where R2-D2 would be blue. But, in Return of the Jedi, you can see on the Death Star a black and red R2 unit with colours placed very differently from R2-D2's . Feel free to ask about specific details if you feel this answer is incomplete.

According to the same source (Legends via Wookieepedia), the R2-AG-series made use of old R5-series shells when the latter series was discontinued. The R2-AG-series was a line of agromech droids, which sounds much more useful when moisture farming then an astromech droid. As evidenced by the quote, Luke thought Red to be an R2-series unit.

Most hyperspace capable star fighters we know of required an R2 or other Astromech unit, including those used by the Jedi, those used by Naboo, and those used by the Rebel Alliance. Astromech droids, and specifically R2 units are seen being used on star ships for maintenance tasks, including 3 or 4 on the queen's ship alone.

2011年10月5日 · So an R2 could potentially do quite a bit to affect the performance of an X-Wing by in effect reprogramming it (or adjusting programming parameters) on the fly. Compensating for an overheating or damaged engine, control thruster, or failing shield generator are all things that can be considered "repair" and would result in the X-Wing ...

2015年12月29日 · Front and center are C-3PO and BB-8. Off to the side (and behind another person) is an R2 unit. One would expect, that if that was R2-D2, he would have been standing in close proximity to the two droids in the middle given R2-D2's importance. That this expectation is not met indicates thats not R2-D2.

2012年8月28日 · The millionth R2 unit would be R2-LFLS, still pronounceable by humans in a hurry. Bumping up to five digits would get you 60 million droids. Considering that doesn't count alternate lines like the QT, R2-AG, or R2-R, (and considering that sci-fi writers have no sense of scale ), I think that's more than enough serial numbers to be plausible.

2020年12月22日 · This decision affects all optional R2, R3 and R4-adapted leg-bracket and barrel-housed propellant rocket systems. IA is instead recommending feature swap outs after 20 years, regardless of actual logged hours of operation.” Additionally, this bit of trivia on R2-D2’s operational state is official canon as well; bold emphasis is mine:

2015年10月7日 · R5-D4 then changed hands once again in Mos Eisley, being sold to Voren Na'al, Rebel Alliance historian and spy. While communicating with the droid through a datapad, Na'al learned a great deal about the sale of R2-D2 and C-3PO to Owen Lars. Na'al then refurbished the maltreated droid and installed an intelligence gathering software package.

2019年12月27日 · There is no reason to think, after all this time, that R2-D2 could stand up like this just because a droid with a similar head could do so. (Out of universe, I expect the similarity was intentional, to make us think the droid were an R2 unit for …

2016年9月12日 · I regret that I am unable to present my father’s request to you in person, but my ship has fallen under attack and I’m afraid my mission to bring you to Alderaan has failed. I have placed information vital to the survival of the Rebellion into the memory systems of this R2 unit. My father will know how to retrieve it.
