Software repository

Directory structure

On the Raspberry the main directory and files are:

/home/local/
+-git        - Directory for libratyes available from a GIT repository (mostly Teensy/arduino libraries).
+-svn        - Directory for software from the subversion repository (Robobot specific software).
|  +-regbot  - Directory for the Teesny software (firmware) this part is called Regbot.
|  |  +-regbot_gui Debug app for Regbot.
|  |  +-regbot     The firmware source code.
|  +-robobot - Directory for the Robobot specific code.
|  |  +-setup      Directory with some default configuration files.
|  |  +-raubase    The basic Raspberry Pi software for Robobot.
|  |  |  +-src     Source code 
|  |  |  +-build   Build directory with Makefile
|  |  |  |  +-log  Directory for data-monitoring logfiles
|  |  |  CMakeList.txt   Directives to generate a Makefile using cmake
|  |  |  robot.ini       Configuration and calibration file
|  |  +- ip_disp   Small app to update the IP address of the Raspberry.
|  |     log_ip_dist.txt Logfile for IP and temperature monotoring
|  +-log     - Directory with logfiles from ip_disp (IP, users and CPU temperature)
on_reboot.bash  - Script to start applications that should start after a reboot (ip_disp)

Development notes

This section is for development notes.

Software installation Raspberry Pi

Install on Raspberry

Barebone installation (Raspbian GNU/Linux 11 (bullseye) as of July 2023)

Raspberry base install

Raspberry wifi

make a bootable SD card
Make a new user called local and set the group permissions

sudo adduser local gpio

Install general-purpose development packages

User and network (WiFi)

Connect to DTU Wifi

connect to DTU network without with secret password
use NTP (network time protocol) with DTU network

Enable autostart

Display of IP

Start app to display IP on Regbot display, log CPU temperature and synchronize hostname

Hostname update

A script updates the Raspberry Pi hostname, with the name in ~/svn/log/robotname. The script rename_host.bash is:

#!/bin/bash
hn=`hostname`
f="/home/local/svn/log/robotname"
if [ -f $f ]; 
then
 nn=`cat $f`
 yy= $(expr length $nn)
 if [ $yy -gt 2 ];
 then
   if [ $hn != $nn ]; 
   then
     sed -i "s/$hn/$nn/g" /etc/hostname
     sed -i "s/$hn/$nn/g" /etc/hosts
   else
     echo Same hostname, all is fine.
   fi
 fi
else
 echo "No robot name file: "  $f
fi

Additional packages

Install the following packages:

libreadline-dev
libopencv-dev
libgpiod-dev
gpiod
cmake
subversion
aptitude
telnet
nmap
lsof
sudo apt install libreadline-dev libopencv-dev libgpiod-dev gpiod cmake subversion aptitude telnet nmap lsof

and, if available

sudo apt install libcli11-dev

Install command line interface library (if not found by 'apt install libcli11-dev')

cd
cd git
git clone https://github.com/CLIUtils/CLI11.git

Install the GPIO library to access pins on the Raspberry PI.

sudo apt install libpigpiod-if-dev

Robobot base software

To make the initial copy from the repository

cd
cd svn
svn checkout svn://repos.gbar.dtu.dk/jcan/robobot

To update with a new version

cd
cd svn/robobot
svn update

Teensy

Software tool chain installation

Old Robobot pages

robobot an extension to Regbot with a raspberry pi for more extended missions, but uses mission code in Teensy, like Regbot.
