Yep, while Rey and Finn might get all the attention, these reliable little robots are helping to overcome the evil empire while all those grown-up aliens are squabbling over who's going to clean out the Porg toilet.
But even though R2-D2 and BB-8 are best, if it came to a head-to-head, only one of them could win - so which one would you choose?
Well, let's take a closer look at what's required to be best of the bots...
You'll need more than just a Swiss Army knife if you want to take on Kylo Ren and his Sith pals.
Luckily, both R2-D2 and BB-8 both have some tricks up their metal sleeves.
But which robot will win?
Beep bop, beep, bop, beep, beep, beep.
That's actually the sound of a popular droid joke and if you speak robot, you'll know it's very funny.
So you can understand, sound is just as important for bot, as it is for us.
But is it R2-D2 or BB-8 who beeps best?
Some robots can be super-fast. Usain Bolt? Yep, the clue's in the name - he's a bot too, and just goes to show how quick those bots can be - so will BB beat R2 in this round?
There's loads of Star Wars films and they all star droids - but how many? And which ones?
All this thinking is making us tired!
Hey, robots may be cold, metallic lumps of wires and emotionless circuitery, but don't say they can't have a personality.
Just talk to Mark Zuckerberg.
But when it comes to charisma, R2-D2 and BB-8 are ready to roll, but which one will come out on top?
