===Opencv 3.4===
 +
 +
It should be OK just to install libopencv-dev - in December 2020 this installs version 3.2.0
 +
 +
sudo apt install libopencv-dev
 +
 +
To find the installed version of OpenCV try
 +
 +
pkg-config --modversion opencv
 +
 +
To install newer OpenCV version 3.4  (as of Jan 2020 it is version 3.4.9)
 +
 +
cd
 +
mkdir -p git
 +
cd git
 +
# this method will install version 4.2 - that is not fully compatible (jan 2020)
 +
# git clone https://github.com/opencv/opencv.git
 +
# git clone https://github.com/opencv/opencv_contrib.git
 +
# use this to get a version compatible with opencv 3.4
 +
# get source (jan 2020)
 +
wget -O opencv-3.4.zip https://github.com/Itseez/opencv/archive/3.4.zip
 +
unzip opencv-3.4.zip
 +
wget -O opencv_contrib-3.4.zip https://github.com/Itseez/opencv_contrib/archive/3.4.zip
 +
unzip opencv_contrib-3.4.zip
 +
# compile the lot, but ommit python3 support, as the compile will fail (as of jan 2020)
 +
cd opencv
 +
mkdir build
 +
cd build
 +
# create makefiles, also for all modules in the opencv_contrib (e.g. ArUco code detect)

 +
# inspect printout to see if needed features are enabled
 +
# use -j2 option not to overload or overheat the processor (j2 means use 2 cores only)
 +
# this probably takes more than an hour.
 +
# if the compilation crashes about halfway or so, it is probably due to lack of memory
 +
#    then just start the compile again, and it is likely to continue (at least for a while)
 +
make -j2
 +
# install into /usr/local
 +
sudo make install
 +
# load environment settings

===ROBOBOT mission demo C++===
+
−
 
+
−
This is an example software in C++ to access both raspberry camera and REGBOT, and with an example mission controlled from the raspberry.
+
−
 
+
−
Get the ROBOBOT software from the svn repository:
+
−
 
+
−
svn checkout svn://repos.gbar.dtu.dk/jcan/regbot/mission mission
+
−
 
+
−
or just update if there already
+
−
 
+
−
svn up
+
−
 
+
−
To be able to compile the demo software CMAKE needs also to use the user installed library (raspicam installed above),
+
−
so add the following line to ~/.bashrc:
+
−
 
+
−
export CMAKE_PREFIX_PATH=/usr/local/lib
+
−
 
+
−
Then build Makefiles and compile:
+
−
 
+
−
cd ~/mission
+
−
mkdir -p build
+
−
cd build
+
−
cmake ..
+
−
make
+
  
−
Then test-run the application:
+
$ amixer
 +
  Simple mixer control 'PCM',0
 +
    Capabilities: pvolume pvolume-joined pswitch pswitch-joined
 +
    Playback channels: Mono
 +
    Limits: Playback -10239 - 400
 +
    Mono: Playback 400 [100%] [4.00dB] [on]
  
−
./mission
+
An thus:<br>
 +
Setting the sound level can be done by:
  
−
It should print that the camera is open and connected to the robot (bidge).
+
amixer set PCM 0dB unmute
  
−
====Software structure====
+
Setting to maximum (100%) is about the same as setting 4dB (may be too much for amplifier).
  
−
The software is structures as shown in figure 1 below.
+
amixer set PCM 100% unmute
  
−
[[file:mission-software.png | 500px]]
+
===Regbot GUI===
  
−
Figure 1. The example mission software intended as basis for full mission control. In the main.cpp file, three objects are created: bridge (UBridge reg(127.0.0.1)), camera (UCamera cam()) and mission (UMission mission(&reg, &cam)). The bridge handles communication and stores all data from the robot and the gamepad. The camera can capture images and image processing is intended here. The mission object is intended for splitting long missions into mission snippets that the REGBOT can execute.
+
To run the regbot gui on the raspberry the following package is needed
  
−
The mission class has access to robot data and the camera at all times using the pointers "bot->" and "cam->". e.g. the heading (relative to the start position) and if the yellow gamepad button is pressed, can be fetched as:
+
Additional python packages used
  
−
float heading = bot->pose.h;
+
* python-pyqtgraph
−
bool yellowButton = bot->joy.button[3];
+
* python-qt4-gl
 +
* python-serial
 +
* python-scipy
  
−
The sound system can be used for debugging, e.g. add a C++ line like:
+
sudo apt install python-pyqtgraph python-qt4-gl python-serial python-scipy
  
−
system("espeak \"bettina reached point 3\" -a30 -s130");
 
  
−
This line makes the robot say "bettina reached point 3" the parameters "-a30" turns amplitude down to 30%, and "-s130" makes the speech a little slower and easier to understand.
+
=====* no python-pyqtgraph =====
−
It requires that espeak is installed (sudo apt install espeak).
+
  
−
===USB as SOCKET for REGBOT client===
+
On my 14.04 32 bit ubuntu the python-pyqtgraph package was not found using apt-get, so I
  
−
This is not compatible with use of ROBOBOT_BRIDGE, so '''don't use it''' here
+
downloaded from http://www.pyqtgraph.org/
 +
the debian package ''python-pyqtgraph_0.9.10-1_all.deb'' and installed using:
  
−
To use the REGBOT client through (not on) the raspberry pi, the serial connection /dev/ttyACM0 on the raspberry can be converted to a network port by SOCAT. So install:
+
sudo dpkg -i python-pyqtgraph_0.9.10-1_all.deb
  
−
  sudo apt install socat
+
  sudo apt install python-pyqtgraph
  
−
Add the following line to /etc/rc.local
+
To start the GUI
  
−
  socat TCP-LISTEN:24001,fork,reuseaddr FILE:/dev/ttyACM0,raw,echo=0 &
+
  cd ~/regbot/qtgui
 +
python regbot.py
  
−
This creates a TCP socket server, listening to port 24001 and piping /dev/ttyACM0 to the socket (with no local echo). This only takes the data from the /dev/ttyACM0 when a client is connected to the socket.
+
Connect to network localhost or kill the bridge and connect directly to "/dev/ttyACM0" (not com5 as is the default serial connection).
  
−
Works after a reboot, or the same line on the command prompt.
+
== File sharing for development ==
  
−
This is good for configuring the REGBOT (in REGBOT client connect wifi to IP of robot, e.g. 192.168.0.2).
+
Mirror the local disk on the Raspberry to a PC, make all file editing here, and then on a terminal connection to the robot to compile the software.

[edit] Installation instruction on the raspberry

Install raspberry pi version of Linux on a micro-SD, instructions can be found here:

Install on raspberry first section (prerequisites).

[edit] Opencv 3.4

It should be OK just to install libopencv-dev - in December 2020 this installs version 3.2.0 

sudo apt install libopencv-dev

To find the installed version of OpenCV try 

pkg-config --modversion opencv

To install newer OpenCV version 3.4 (as of Jan 2020 it is version 3.4.9) 

cd
mkdir -p git
cd git
# this method will install version 4.2 - that is not fully compatible (jan 2020)
# git clone https://github.com/opencv/opencv.git
# git clone https://github.com/opencv/opencv_contrib.git
# use this to get a version compatible with opencv 3.4
# get source (jan 2020)
wget -O opencv-3.4.zip https://github.com/Itseez/opencv/archive/3.4.zip
unzip opencv-3.4.zip
wget -O opencv_contrib-3.4.zip https://github.com/Itseez/opencv_contrib/archive/3.4.zip
unzip opencv_contrib-3.4.zip
# compile the lot, but ommit python3 support, as the compile will fail (as of jan 2020)
cd opencv
mkdir build
cd build
# create makefiles, also for all modules in the opencv_contrib (e.g. ArUco code detect)
# cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_opencv_python3=OFF -D OPENCV_EXTRA_MODULES_PATH=~/git/opencv_contrib/modules ..
cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_opencv_python3=OFF -D OPENCV_EXTRA_MODULES_PATH=~/git/opencv_contrib-3.4/modules ..
# inspect printout to see if needed features are enabled
# use -j2 option not to overload or overheat the processor (j2 means use 2 cores only)
# this probably takes more than an hour.
# if the compilation crashes about halfway or so, it is probably due to lack of memory
#    then just start the compile again, and it is likely to continue (at least for a while)
make -j2
# install into /usr/local
sudo make install
# load environment settings
sudo ldconfig

[edit] Raspicam

NB! this should not be needed

A rather short raspberry pi camera API is available from https://www.uco.es/investiga/grupos/ava/node/40. And can be downloaded from https://sourceforge.net/projects/raspicam/files/,

or get the file from sourceforge with no GUI, with: 

cd ~/Downloads
wget --no-check-certificate -O raspicam-0.1.9.zip https://downloads.sourceforge.net/project/raspicam/raspicam-0.1.9.zip?r=https%3A%2F%2Fsourceforge.net%2Fprojects%2Fraspicam%2F%3Fsource%3Dtyp_redirect&ts=1486483484&use_mirror=netix

Once fetched and available on the raspberry, then Unpack and install: 

unzip raspicam-0.1.9.zip
cd raspicam-0.1.9
mkdir build
cd build
cmake ..
make
sudo make install
sudo ldconfig

The library is installed in /usr/local, and therefore to make cmake find it the path needs to be added to startup configuration, in file ~/.bashrc 

nano ~/.bashrc
add at the end:
export CMAKE_PREFIX_PATH=/usr/local/lib

(needs a re-logon to be activated, or repeat on the command line)

[edit] DNSMASQ

To enable the ROBOBOT to be connected directly to a PC, then it is easier if the ROBOBOT provides an IP for the PC.

Install DNSMASQ 

sudo apt install dnsmasq

allow dnsmasq to provide IP to pear-to-pear networks Edit the /etc/dnsmasq.conf (nano is a small text editor, fine for editing configuration files owned by Linux root) 

sudo nano /etc/dnsmasq.conf
find and change/add the following line (a bit down, eg to serch use: ctrl-W dhcp-range)
dhcp-range=192.168.17.100,192.168.17.150,12h

To work, the eth0 must have an IP, if noone provides one, change /etc/dhcpcd.conf (dhcp client deamon) to have a default IP, if no DHCP server is available

Edit of /etc/dhcpcd.conf to have a fall back behaviour for eth0 and eth1. 

sudo nano /etc/dhcpcd.conf
Add the following lines at the end (uncomment and modify):
# define static profile
profile static_eth0
static ip_address=192.168.17.1/24
# static routers=192.168.0.1
# static domain_name_servers=192.168.0.1

# fallback to static profile on eth0
interface eth0
fallback static_eth0

This will also give a default IP for an eventual second network (usb-to-cable) if needed

Now, after a reboot, you should be able to connect a PC directly with at network cable to a PC, and the PC should get an IP from the raspberry, so now 

ssh local@192.168.17.1

[edit] Sound

[edit] festival

Easy understandable voice, but takes time to generate and require two intermediate files 

sudo apt install festival
echo "The brown fox jumps over lazy dog" > aaa.txt
text2wave aaa.txt -o aaa.wav
aplay aaa.wav

[edit] Music files

This part works

Play sound files, like 

sudo apt-get install sox libsox-fmt-all
play -v0.1 music.mp3

This line plays an mp3 file with volume reduced by a factor 0.1. The at startup the blue button on the gamepad plays the file in /home/local/Music/music.mp3.
This is a symbolic link to some real music (Radetzky Marsch in this case): 

ls ~/Music
   radetzky-marsch_Schloss-Schoenbrunn-Konzerte_Wien_full-length.mp3
cd ~/Music
ln -s radetzky-marsch_Schloss-Schoenbrunn-Konzerte_Wien_full-length.mp3 music.mp3

[edit] Sound level

On a Raspberry pi version 3+ (not tested on other versions) 

$ amixer
 Simple mixer control 'PCM',0
   Capabilities: pvolume pvolume-joined pswitch pswitch-joined
   Playback channels: Mono
   Limits: Playback -10239 - 400
   Mono: Playback 400 [100%] [4.00dB] [on]

An thus:
Setting the sound level can be done by: 

amixer set PCM 0dB unmute

Setting to maximum (100%) is about the same as setting 4dB (may be too much for amplifier). 

amixer set PCM 100% unmute

[edit] Regbot GUI

To run the regbot gui on the raspberry the following package is needed

Additional python packages used

  • python-pyqtgraph
  • python-qt4-gl
  • python-serial
  • python-scipy 
sudo apt install python-pyqtgraph python-qt4-gl python-serial python-scipy


[edit] * no python-pyqtgraph

On my 14.04 32 bit ubuntu the python-pyqtgraph package was not found using apt-get, so I

downloaded from http://www.pyqtgraph.org/ the debian package python-pyqtgraph_0.9.10-1_all.deb and installed using: 

sudo dpkg -i python-pyqtgraph_0.9.10-1_all.deb

sudo apt install python-pyqtgraph

To start the GUI 

cd ~/regbot/qtgui
python regbot.py

Connect to network localhost or kill the bridge and connect directly to "/dev/ttyACM0" (not com5 as is the default serial connection).

[edit] File sharing for development

Mirror the local disk on the Raspberry to a PC, make all file editing here, and then on a terminal connection to the robot to compile the software.

[edit] Share files from windows

On the windows computer install "winscp" and use it to copy files to and from the raspberry disk as needed.

There are other methods too.

[edit] Share files on Linux

On a Linux PC use sshfs for sharing. Make an empty directory for the mapped disk, and then mount 

mkdir robobotdisk
sshfs local@192.168.0.2: robobotdisk

Unmount with 

fusermount -u robobotdisk

Or use "sudo unmount robobotdisk"
