Hardware documementation

Supported hardware

We support the following hardware:

• Raspbery Pi 4 or 5 without any special hardware (bunch of of-the-shelf components and 3D printed parts)
• Raspbery Pi 4 Compute module with custom carrier board. The carrier board is not part of this repository and is available on request.

Both version shares the same software, but are different in hardware (e.g. different GPIO layout, some extra features on custom carrier board). The target hardware is defined during compilation time. If you want to extend this project to different platforms or hardware, please refer to source code available in hardware directory.

3D Model

The source design is available on Onshape, and you can access it here.

The design files for 3D printing are available in the repository's 3mf directory. You can find the file ScannerAssembly.3mf containing the models to be printed.

For optimal results, we recommend printing the assembly with PLA. Don't forget to adjust the 3MF file according to your printer specifications. If you need assistance with this, consider including a brief guide or tips on printer adjustments.

Additionally, we recommend printing a protective cap for Livox Mid-360, which you can find in the LivoxCap.3mf file.

Feel free to reach out if you have any questions or need further assistance!

Software

Important notes

Currently Raspbian Bullseye is recommended for the system. The system is tested on Raspbian Bullseye. The software can run other distros (e.g. Ubuntu) but it is not tested and maintained.

Update system

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential cmake git rapidjson-dev debhelper build-essential ntfs-3g libserial-dev libgpiod-dev

Static IP for eth0

sudo nano /etc/dhcpcd.conf

And add in the end:

interface eth0
static ip_address=192.168.1.5/24
static routers=0.0.0.0    

Clone and build app

Note that, target hardware is defined during compilation time using -DMANDEYE_HARDWARE_XXX:BOOL=ON parameter. The next example shows how to build the app for Raspberry Pi 4 without custom carrier board.

git clone https://github.com/JanuszBedkowski/mandeye_controller.git
cd mandeye_controller
git submodule init
git submodule update
mkdir -p build && cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DMANDEYE_HARDWARE_STANDARD:BOOL=ON
make -j4

Test wiring and hardware

Before running the application, you should test the wiring and hardware. You can use the following commands to test the hardware:

cd mandeye_controller/build
./led_demo
./button_demo

Both program should work correctly, without need of sudo. If not , check if your user is in gpio group, if not add it:

sudo usermod -a -G gpio $USER

Set USB mount

Follow manual for build and configuration of USB mount https://gist.github.com/michalpelka/82d44a21c29f34ee5320c349f8bbf683

cd /tmp
git clone https://github.com/rbrito/usbmount.git
cd usbmount
dpkg-buildpackage -us -uc -b
cd ..
sudo apt install ./usbmount_0.0.24_all.deb

Edit config sudo nano /etc/usbmount/usbmount.conf: by changing keys:

FILESYSTEMS="vfat ext2 ext3 ext4 hfsplus ntfs fuseblk"
FS_MOUNTOPTIONS="-fstype=vfat,users,rw,umask=000 -fstype=exfat,users,rw,umask=000"
VERBOSE=yes

Install udev rules:

sudo mkdir /etc/systemd/system/systemd-udevd.service.d
sudo nano -w /etc/systemd/system/systemd-udevd.service.d/00-my-custom-mountflags.conf

and add content:

[Service]
PrivateMounts=no

Restart udev:

sudo systemctl daemon-reexec
sudo service systemd-udevd restart

Verify if usb mount works correclty:

touch /media/usb/test

tail -f /var/log/syslog

Setup systemctl for autostart

Create a file /usr/lib/systemd/system/mandeye_controller.service with content. Note that you need to adjust your user's name:

[Unit]
Description=Mandeye
After=multi-user.target

[Service]
User=mandeye
StandardOutput=null
StandardError=null
ExecStartPre=/bin/sleep 20
ExecStart=/home/robot/mandeye_controller/build/control_program
Restart=always

[Install]
WantedBy=multi-user.target

Next reload daemons, enable and start the service`

sudo systemctl daemon-reload
sudo systemctl enable mandeye_controller.service
sudo systemctl start mandeye_controller.service

You can check status of the service with:

sudo systemctl status mandeye_controller.service
