===ROBOBOT demo C++===
+
====festival====
  
This is an examplesoftware in C++ to access both raspberry camera and REGBOT, and with an example mission controlled from the raspberry.
+
Easy understandable voice, but takes time to generate
 +
and require two intermediate files
  
Get the robobot software from the svn repository:
+
sudo apt install festival
 +
echo "The brown fox jumps over lazy dog" > aaa.txt
 +
text2wave aaa.txt -o aaa.wav
 +
aplay aaa.wav
  
svn checkout svn://repos.gbar.dtu.dk/jcan/regbot/robobot robobot
+
====Music files====
  
To be able to compile the demo software CMAKE needs also to use the user installed library (raspicam installed above),
+
This part works
so add the following line to ~/.bashrc:
+
  
export CMAKE_PREFIX_PATH=/usr/local/lib
+
Play sound files, like
  
Then build Makefiles and compile:
+
sudo apt-get install sox libsox-fmt-all
 +
play -v0.1 music.mp3
  
cd robobot
+
This line plays an mp3 file with volume reduced by a factor 0.1.
cd build
+
The at startup the blue button on the gamepad plays the file in /home/local/Music/music.mp3.<br>
cmake ..
+
This is a symbolic link to some real music (Radetzky Marsch in this case):
make
+
  
Then testrun the application:
+
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
  
./robobot
+
===Sound level===
  
It should print that the camera is open, save an image and print some data from the robot (e.g. position).
+
On a Raspberry pi version 3+ (not tested on other versions)
  
===USB as SOCKET for REGBOT client===
+
$ 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]
  
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:
+
An thus:<br>
 +
Setting the sound level can be done by:
  
  sudo apt install socat
+
  amixer set PCM 0dB unmute
  
Add the following line to /etc/rc.local
+
Setting to maximum (100%) is about the same as setting 4dB (may be too much for amplifier).
  
  socat TCP-LISTEN:24001,fork,reuseaddr FILE:/dev/ttyACM0,raw,echo=0
+
  amixer set PCM 100% unmute
  
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.
+
===Regbot GUI===
  
Works after a reboot, or the same line on the command prompt.
+
To run the regbot gui on the raspberry the following package is needed
  
This is good for configuring the REGBOT (in REGBOT client connect wifi to IP of robot, e.g. 192.168.0.2).
+
Additional python packages used
  
===Share files from windows===
+
* python-pyqtgraph
 +
* python-qt4-gl
 +
* python-serial
 +
* python-scipy
  
To share files on all windows computers (without need for administrator) configure a samba share
+
sudo apt install python-pyqtgraph python-qt4-gl python-serial python-scipy
(or follow Simon on http://simonthepiman.com/how_to_setup_windows_file_server.php)
+
  
First install samba
 
  
sudo apt install samba samba-common-bin
+
=====* no python-pyqtgraph =====
  
then edit /etc/samba/smb.conf
+
On my 14.04 32 bit ubuntu the python-pyqtgraph package was not found using apt-get, so I
  
sudo nano /etc/samba/smb.conf
+
downloaded from http://www.pyqtgraph.org/
 +
the debian package ''python-pyqtgraph_0.9.10-1_all.deb'' and installed using:
  
comment out all lines under the headlines:
+
  sudo dpkg -i python-pyqtgraph_0.9.10-1_all.deb
  [homes]
+
[printers]
+
[print$]
+
[cdrom]
+
  
Add the following section at the end:
+
sudo apt install python-pyqtgraph
  
[robobot]
+
To start the GUI
comment = Raspberry Pi user LOCAL home directory
+
path = /home/local
+
writeable = Yes
+
only guest = Yes
+
create mask = 0777
+
directory mask = 0777
+
browseable = Yes
+
public = yes
+
  
 +
cd ~/regbot/qtgui
 +
python regbot.py
  
Add "local" and "pi" as a samba user (and set password, for user pi it should be "raspberry"):
+
Connect to network localhost or kill the bridge and connect directly to "/dev/ttyACM0" (not com5 as is the default serial connection).
  
sudo smbpasswd -a local
+
== File sharing for development ==
sudo smbpasswd -a pi
+
  
Reboot to implement
+
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.
  
sudo reboot
+
===Share files from windows===
 
+
====Windows map drive====
+
 
+
On the windows computer, connect a network cable directly between the robobot and the computer, e.g. using a USB to Ethernet converter. Robobot should now be available with network address 192.168.0.2 (you could try a ping if in doubt).
+
 
+
In the file browser:
+
* select "map network drive" (menu tools, or right-click on "my computer").
+
* select drive R: (for robobot) - or another if R is used already.
+
* in the folder field write: \\192.168.0.2\robobot, and select "Connect using different credentials", then OK.
+
* Type in username (local or pi) and the appropriate password (and OK).
+
  
Now the code and other files can be accessed and manipulated from windows, e.g. using an IDE.
+
On the windows computer install "winscp" and use it to copy files to and from the raspberry disk as needed.
  
* But the code still needs to be compiled on the raspberry (install and use putty for a ssh terminal access)
+
There are other methods too.

[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

# 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"
