See, it turns out that the Rabbit R1 seems to run Android under the hood and the entire interface users interact with is powered by a single Android app. A tipster shared the Rabbit R1’s launcher APK with us, and with a bit of tinkering, we managed to install it on an Android phone, specifically a Pixel 6a.
Edit: Someone also got doom and Minecraft running on this thing
“rabbit r1 is not an Android app. We are aware there are some unofficial rabbit OS app/website emulators out there. We understand the passion that people have to get a taste of our AI and LAM instead of waiting for their r1 to arrive. That being said, to clear any misunderstanding and set the record straight, rabbit OS and LAM run on the cloud with very bespoke AOSP and lower level firmware modifications, therefore a local bootleg APK without the proper OS and Cloud endpoints won’t be able to access our service. rabbit OS is customized for r1 and we do not support third-party clients. Using a bootlegged APK or webclient carries significant risks; malicious actors are known to publish bootlegged apps that steal your data. For this reason, we recommend that users avoid these bootlegged rabbit OS apps.”
So there's literally no reason for this to have been a device at all.
You'd be surprised how many companies ignore GPL. Providing broken links to the source code tarballs, telling you to send an email request to get the code then proceed to ignore the requests, etc. Only the most famous case got sued, the rest simply got away with it.
And there are other funny solutions, like when a Chinese "tech influencer/diy maker" Naomi Wu aka SexyCyborg just simply walked into the office of a Chinese manufacturer, and requested the source code in person: https://www.youtube.com/watch?v=Vj04MKykmnQ
They wrote "lower level firmware modifications", AOSP runs on Linux kernel, and firmware modifications usually mean they modified the Linux kernel. This device seems like a regular Android phone, and afaik this rules apply to all Android phones, that's why Android rom cooking can exist.
They may be compelled to release any driver code associated, however firmware is not covered by relation to kernel. Linux runs on mostly proprietary firmware. The "linux-firmware" package in many distributions that contains hot plug firmware is mostly proprietary blobs.
That said I doubt they had much significant firmware work, it may just be logo and some tweaked configuration from their SoC vendor. They likely had to modify AOSP a bit more to allow their launcher unfettered access to the device in ways not modeled by standard AOSP, but that's user space that isn't GPL.
This was a marketing post, not a technical one. Unless we see any git branches or ROM teardown we won't know what they were doing. I highly doubt that they did any kernel patches though.
Except that some people may like this form factor for these features. Of course it can be delivered in phones, but it does seem at least possible to me that some may prefer a device like this.
I love the dumb little form factors those guys do. The only thing stopping me is that I know it is overhyped bullshit which I will be bored of in a week. If it were easy to develop my own software to completely replace what's on it I might be convinced.
They're possibly complimentary but not mutually exclusive. I think if they sold the form factor of the device over the phone that that would have been more honest marketing.
