The [[naoqi]] operating system the robot runs uses linux kernel version <code>4.4.185-rt184-aldebaran</code>


The Nao runs an <code>Intel Atom E3845</code> from 2013. The architecture is <code>x86_64</code>. [[Nao Robot Cpu Info|CPU Info]]

It has <code>4GB</code> of RAM.

My Nao has a mac address of <code>00:13:95:1f:86:1d</code> on Ethernet and <code>b8:b7:f1:15:f6:11</code> on Wi-Fi

Obtaining Root access on the operating system
<hr>
The operating system image comes in the <code>.opn</code> format. It can be extracted using <code>7z x file.opn</code> The <code>.ext3</code> image inside the file can be mounted using <code>sudo losetup --show --partscan -f image.ext3</code>


Once the image is mounted, you can chroot into it by running <code>sudo chroot .</code> from the root of the mounted image. Then you can change the root password using <code>passwd</code>


You can rebuild the image to the <code>.opn</code> format using the following scripts provided by NaoDevils:

https://raw.githubusercontent.com/BackThrowTheBaguetteBrawler/NaoImage/refs/heads/master/installer.sh

 ./generate_opn.sh image.ext3 2.8.7.4_20210820_094013-rootpasswordAltered.opn

The image can now be flashed to a USB drive using NaoFlasher. To install the image to the robot, plug the usb drive into his usb port, and hold his chest button down for 6 seconds.
