This project took the open source code from SunFounder Picar-V (as in video) project and modified it to enable a new UI interface. It also got rid of any Django dependencies. To the best of my abilities it only uses modules available in the Ubuntu archive + pip3. The car itself was modified with a new battery pack (from SunFounder) so as to enable one member of my team (-Ogra-) to design a charging station -facility- . This is all for conference and trade shows but hopefully a few hobbyists can also reuse what I did. TO USE, YOU WILL NEED TO CONNECT INTERFACES, since it is in strict confinement. It is meant to work with Ubuntu Core (tested on Core 22), but Core 22.04 works too. INSTALLATION First, install the snap (snap install core-car). Then, connect your interfaces on Core, otherwise the OS will not give access snap connect core-car:name_of_plug snapd:name_of_slot It should look like this skidooman@core-car~$ snap connections core-car Interface Plug Slot Notes camera core-car:camera :camera manual gpio-memory-control core-car:gpio-memory-control :gpio-memory-control manual home core-car:home :home manual i2c core-car:i2c pi:i2c-0 manual i2c core-car:i2c pi:i2c-1 manual network core-car:network :network - network-bind core-car:network-bind :network-bind - I would then sudo snap restart core-car, and it should work.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for Red Hat Enterprise Linux (RHEL) 8 and RHEL 7, from the 7.6 release onward.
The packages for RHEL 7, RHEL 8, and RHEL 9 are in each distribution’s respective Extra Packages for Enterprise Linux (EPEL) repository. The instructions for adding this repository diverge slightly between RHEL 7, RHEL 8 and RHEL 9, which is why they’re listed separately below.
The EPEL repository can be added to RHEL 9 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 8 with the following command:
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf upgrade
The EPEL repository can be added to RHEL 7 with the following command:
sudo rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
Adding the optional and extras repositories is also recommended:
sudo subscription-manager repos --enable "rhel-*-optional-rpms" --enable "rhel-*-extras-rpms"
sudo yum update
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap
and /snap
:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again or restart your system to ensure snap’s paths are updated correctly.
To install ucore-car, simply use the following command:
sudo snap install ucore-car
Browse and find snaps from the convenience of your desktop using the snap store snap.
