====festival====
  
−
Get the robobot software from the svn repository:

====Music files====
−
so add the following line to ~/.bashrc:

Play sound files, like
  
−
  cd mission

  sudo apt-get install sox libsox-fmt-all
−
  cd build
+
  play -v0.1 music.mp3
−
cmake ..
+
−
make
+
  
−
Then test-run the application:
+
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.<br>
 +
This is a symbolic link to some real music (Radetzky Marsch in this case):
  
−
  ./mission
+
  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

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 sensors and the gamepad. The camera can capture images and image processing is intended here. The mission object is intended for splitting ling missions into mission snippets that the REGBOT can execute.

Setting the sound level can be done by:
  
−
===USB as SOCKET for REGBOT client===
+
amixer set PCM 0dB unmute
  
−
This is not compatible with use of ROBOBOT_BRIDGE, so don't use it here
+
Setting to maximum (100%) is about the same as setting 4dB (may be too much for amplifier).
  
−
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:
+
amixer set PCM 100% unmute
  
−
sudo apt install socat
+
===Regbot GUI===
  
−
Add the following line to /etc/rc.local
+
To run the regbot gui on the raspberry the following package is needed
  
−
socat TCP-LISTEN:24001,fork,reuseaddr FILE:/dev/ttyACM0,raw,echo=0 &
+
Additional python packages used
  
−
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.
+
* python-pyqtgraph

[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

# 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"
