Book with a robot that had a teapot/kettle as a head?
Ok this is actually driving me crazy I swear I've read a book like this before but I can't find it anywhere. I recall searching for it a few years back without success. I even tried looking through local library catalogues, but I couldn't find it. Of course, it could just be that I used the wrong keywords/publication dates/filters when searching. Or maybe I imagined this whole book. Also, it has been many years since I've seen or even thought about this book, so I cannot guarantee that any of the details are even remotely accurate.
The book is MG/YA maybe, and it had a blue cover. The cover was very minimalistic, just the title and 2 white/light blue humanoid silhouettes with similar heights standing next to each other in a neutral pose. I think one silhouette was meant to be the main character, who i think was a girl? The other one has a teapot-like thing instead of a head and in the story it was specified that this was supposed to be the robot, who had a kettle for a head. I think they found the robot or maybe built it or something but it was missing a head so they just used a kettle as a placeholder?
I don't remember much of the plot, but one of the big things was that there was binary ASCII in the text and I had to use an online translator to translate. I think there was even a whole page of just binary at one point. I think some of the binary was dialogue from the robot. Also, I don't think the robot character interacted much with anyone other than the main character.
I vaguely recall the title being "IO", or perhaps "10" or "I0", but nothing comes up when I search for it, so I'm probably just remembering it wrong. I remember the title being the same, or similar to, the name of the robot.
I read this book around 2016-2018, or maybe a bit later, so I suspect it was published around 2000s or 2010s, but it could be older. I read this book if it exists in New Zealand, if that helps.
Also, the more details I write, the more I'm beginning to think that my brain made some of this up, so I'll take any clue as to what this book might be, even if what I said doesn't match up. It isn't unlikely that I've mixed up 2 or more books, so even books with details that kinda sorta match are appreciated. It is also possible that I just straight up imagined this book.
