Binary. Binary, or Droidspeak, is made up of beeps and whistles. The language is “spoken” by droids such as R2-D2 and BB-8.
C-3PO, his robot companion, could speak 6-million languages including excellent English with a hint of a British accent and all R2-D2 could muster were beeps and whistles. Clearly the technology was there to let him speak, but whoever designed him intentionally decided to stick with the beeps and whistles.
Binary, also known as Droidspeak, was the droid language composed of electronic beeps, bloops, buzzes, chirps, whines, and whistles. All droids could "speak" and understand Binary.
Most are quite intelligent, and some can even speak the human language, such as C-3PO. However, most droids, including R2-D2 and BB-8, "speak" a droid language through sequences of beeps and whistles. It is known as "Binary," and several humans in the Star Wars universe can understand it.
One of the most significant changes revealed on the official Star Wars website was that R2-D2 would have spoken English instead of emoting through various sound effects. This design choice would have meant that R2, much like his partner C-3PO, would have had a distinct voice that spoke in full and articulate sentences.
Wanna know how to say "I love you" in Droid? You guessed it: "Bleep bloop."
Further in Empire Strikes Back, neither Yoda nor Darth Vader recognizes either droid. Luke travels with R2-D2 to the Dagobah where they find Yoda. Yoda's relationship with R2-D2 is not on the same level with the same characters. Perhaps, the old creature simply forgot.
Anakin and Luke can also speak “binary,” the language of the droids, giving them a window onto the experience of their robotic companions.
The ultimate secret of R2D2's emotive character is that sound designer Ben Burtt actually combined his own voice with the sound of the synthesizer to create baby-like wails and cries in addition to the computer-like sounds of the Arp. It's this unique combination that gives R2D2 its own organic life.
The C1-series astromech droid utilized this form of communication, as did Industrial Automaton's R2 series astromech droid. While difficult, some organics such as Anakin Skywalker, Hera Syndulla, Kazuda Xiono, Cal Kestis, and Rey were able to understand it.
Obi-Wan Kenobi was another human who could speak Binary, as well as Anakin, who shared the strongest relationship with R2-D2, as seen in the prequel trilogy and Star Wars: The Clone Wars.
“You use English words but retain some of the structures from that native language.” The professor has concluded that Yoda's original language, which he “grew up speaking”, was Hawaiian.
Note: Canon sources are mixed as to whether R2-D2 has a gender, but Wallace (an official source) indicates that the droid has masculine programming.
Yoda recognized R2-D2 during The Empire Strikes Back.
In the original script for "A New Hope," which was revealed on Twitter in 2016 by original Chewbacca actor, the late Peter Mayhew, R2-D2 spoke in "a flurry of electronic swearing," which is pretty great. Threepio reacts as expected, which is exactly like your grandparents might.
During this week's edition of The Star Wars Show web series, Lucasfilm revealed the first look and details of the droid C2-B5. He (or, rather, it) is essentially a black-painted R2-D2 because, as we learn in the video shown below, both are part of the astromech droid family.
Because droids learn and grow, R2-D2 has grown smarter and more intelligent without a memory wipe. But he has also been associated and working with some of the most powerful and knowledgeable people in the Galaxy (Anakin most specifically, but he was on missions with many other Jedi as well).
The A button is also used to open the lights on and off menu when R2-D2 sleeps; R2-D2 in his base form sleeps at 8 PM * , while all of the special skill forms sleep at 10 PM. R2-D2 will wake up at 7 AM, and will turn the lights on himself.
It is Mayo's first feature-length film and tells the story of Luke, a young man with autism who embarks on a quest for a job and a girlfriend. It stars Lou Taylor Pucci, Seth Green, Cary Elwes and Kristin Bauer.
5. Love triangles and awkwardness — The Empire Strikes Back wasn't the first inkling that Luke and Leia had feelings for each other. Their romance was heavily alluded to in A New Hope, what with all of Luke's suggestive facial expressions to Han whenever Leia was around, and Han's clear attraction to Leia.
Undoubtedly, his greatest love was with a character named Mara Jade. Mara is a strong character as a part of the expanded universe of the Star Wars Legends series of novels. Their love is so strong that Luke winds up marrying her, and she bears a son that they name Ben (not Ben Solo).
After the battle, R2-D2 and C-3PO were the sole witnesses to the marriage of Anakin Skywalker and Padmé Amidala in Lake Country. After this Padmé gave ownership of R2 to Anakin while she kept 3PO.
By claiming he's never owned a droid, he applies the same tactic as he did with his embellishment about Anakin. He hasn't owned a droid because R2-D2 is his friend. No one can "own" him, and to claim to have done so disrespects the countless ways the little astromech has saved the galaxy.
During the Clone Wars, it was common practice to wipe the minds of astromech droids after every mission to avoid the risk of Separatists taking valued information. But Anakin remained staunchly against this idea for R2-D2, meaning the droid never had to worry about losing the memories of his past.
