[edit]

DCC-DCC converter

To run the Raspberry PI from the 7.4 Volt Battery of the car the DC-DC converter has to be soldered into the voltage supply chain.

Camera mount

Servo and LED

[edit]

For a start a 3D Printed case for the Raspberry PI was used:

[edit]

Raspbian

Raspbian Stretch with desktop and recommended software

Download Zip File from https://www.raspberrypi.org/downloads/raspbian/
Create SD Card as described in https://www.raspberrypi.org/documentation/installation/installing-images/
Insert SD Card into Raspberry PI
Connect Keyboard, Mouse, HDMI-Monitor and 5 Volt Mini USB (2.5 Amps recommended)
Setup Country, pi user password etc. and connect to your WIFI network - after the setup you'll be asked to restart your pi

WebCam Interface

https://github.com/silvanmelchior/RPi_Cam_Web_Interface

cd /usr/local/src
sudo git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git
cd RPi_Cam_Web_Interface/
./install.sh

In case of error

A message like:

#mmal: mmal_component_create_core: could not create component 'vc.ril.camera' (1)
sh: 1: /var/www/html/macros/error_hard.sh: Permission denied

Indicates that you might have a cabling problem.

In case of success

http://<yourpi>/html should show the cam interface:

Servo Interface - Servoblaster

wf@pibee:~ $ cd /usr/local/src
wf@pibee:/usr/local/src $ sudo git clone https://github.com/srcshelton/servoblaster
cd servoblaster
sudo make install
sudo reboot

OpenJDK

sudo apt-get install openjdk-8-jdk

Screen

sudo apt-get install screen

[edit]

Tested on

Mac OS 10.13.6 High Sierra with macports 2.5.4
Ubuntu 18.04.2 LTS

OpenCV

MacOS

If you'd like to generally use OpenCV you can get it e.g. from the macports project:

sudo port install opencv +java
ls /opt/local/share/OpenCV/java
libopencv_java343.dylib opencv-343.jar

For your convenience you'll find these two files in the lib directory.

Ubuntu 18

You might want to use scripts/opencvubuntu to download the 75 MByte libopencv_java343.so and install the backports libjasper libraries that are not published with Ubuntu 18 by default. You'll find some other links in the script that might also give you hints on how to proceed if you have another environment or different needs. You might want to create an Issue if you run into trouble.

Windows

Help Wanted -please file an issue if you want to things running on Windows.

[edit]

Deploying to your Raspberry is done by compiling e.g. on a laptop and then transferring the results to your PI.

You need to configure your targetHost and targetUser in a file ~/dukes/dukes.ini

Example Configuration

#
# rc-dukes configuration file
# see https://github.com/rc-dukes/dukes
#
targetHost=10.9.8.7
targetUser=pi
# carserver configuration
carserver.port=8080

The deploy script as a help option that shows how it can be used:

deploy.sh [-a|-d|-h|-m|-s]

  -a |--autostart         : configure the remotecar app to autostart on reboot
  -d |--debug             : debug this script
  -m |--maven             : run maven install
  -h |--help              : show this usage
  -s |--start             : deploy and start remotecar (duke) fat jar

deploy -m will create the duke-farm fat jar
deploy -s will send the jar to your PI using rsync and start it
deploy -a will create an autostart configuration that restarts the client on reboot see https://github.com/rc-dukes/dukes/issues/26
