ICub machines configuration

From ISRWiki
Jump to navigation Jump to search

In this page we will list configurations that are commonplace to Linux machines used at Vislab to work with the iCub robot.

See VisLab machines configuration/Archive for obsolete information.

Operating system installation

Follow Ubuntu defaults and partitioning. For servers and critical machines, use LTS releases. Machines involved in demos must have a user named icub, to make the distributed setup possible (this is required by the graphical 'yarpmanager' program). Furthermore, to use the NFS network mount, this user has to have the uid 1000 and guid 1000.

In order to add a user:

  • either use the Ubuntu graphical frontends
  • or use a Terminal: sudo adduser icub followed by sudo usermod -aG admin icub to give it sudo privileges

Other operations

Network configuration

See also: VisLab network, ISR computing resources.

Manually configure your internet connection as detailed in one of the following subsections, depending if the machine is a desktop or a server one.

Optionally, you may also customize the /etc/hosts file; this would allow us to quickly access other machines, as in: ping icbubrain1. Alternatively, we can do nothing and just use ping icubbrain1.visnet (i.e., attach the .visnet part after a machine name, see VisLab network for details).

Desktop machines

With the graphical Network Manager (https://help.ubuntu.com/14.04/ubuntu-help/net-fixed-ip-address.html), configure the connection "Auto eth0" IPv4 as follows:

Address Netmask Gateway DNS Servers notes
10.10.1.x 255.255.255.0 10.10.1.254 10.0.0.1, 10.0.0.2 visnet (iCub machines)
10.0.x.y 255.255.0.0 10.0.0.254 10.0.0.1, 10.0.0.2 isrnet (rest of ISR)

Servers

Edit /etc/network/interfaces like this: 

auto lo
iface lo inet loopback
  
auto eth0
iface eth0 inet static
address 10.x.y.z # put your IP here, see above table
netmask 255.255.x.y # see above table
network 10.10.1.0
broadcast 10.10.1.255
gateway 10.10.1.254
dns-nameservers 10.0.0.1 10.0.0.2

In some versions of Ubuntu, to configure DNS you also need to edit /etc/resolvconf/resolv.conf.d/head like this: 

nameserver 10.0.0.1
nameserver 10.0.0.2

then run: 

sudo resolvconf -u

Dependencies

sudo apt-get install build-essential libace-dev libgsl0-dev libncurses5-dev gfortran libtinyxml-dev
sudo apt-get install git-core subversion ssh gcc g++ make cmake-curses-gui
sudo apt-get install qttools5-dev qtdeclarative5-dev qtdeclarative5-controls-plugin qtmultimedia5-dev qtdeclarative5-qtmultimedia-plugin qtquick1-5-dev

iCub Simulator dependencies: SDL and ODE.

The GTK versions of graphical YARP programs will be discontinued in 2015 (replaced by Qt equivalents). If you still want to obtain the old programs during compilation, do: 

sudo apt-get install libgtkmm-2.4-dev

Environment variables

  • Create a file called ~/.bashrc_iCub like this one:
# /usr/local/src/robot directory can be mounted from NFS, or created manually with permissions:  sudo chown icub.icub /usr/local/src/robot -R
export ROBOT_CODE=/usr/local/src/robot
export YARP_ROOT=$code/yarp
export YARP_DIR=$YARP_ROOT/build
export ICUB_ROOT=$code/icub-main
export ICUB_DIR=$ICUB_ROOT/build
export PATH=$PATH:$YARP_DIR/bin:$ICUB_DIR/bin
source $YARP_ROOT/scripts/yarp_completion
export YARP_DATA_DIRS=$YARP_DIR/share/yarp:$ICUB_DIR/share/iCub
export YARP_ROBOT_NAME=iCubLisboa01 # only for machines that connect to the real robot
export IPOPT_DIR=/home/icub/Ipopt-3.10.2/build # Inverse Kinematics solver - see http://wiki.icub.org/wiki/Installing_IPOPT
export OpenCV_DIR=$code/OpenCV-2.4.8/build # manually installed, with TBB support - see below

If you need icub-contrib type packages, some lines need to be added or changed: 

export ICUBcontrib_DIR=$code/icub-contrib-common/build
export PATH=$PATH:$YARP_DIR/bin:$ICUB_DIR/bin:$ICUBcontrib_DIR/bin
export YARP_DATA_DIRS=$YARP_DIR/share/yarp:$ICUB_DIR/share/iCub:$ICUBcontrib_DIR/share/ICUBcontrib
  • Then, before the following line of /etc/bash.bashrc
[ -z "$PS1" ] && return

add this: 

# per-user environment variables (non-interactive and interactive mode)
source $HOME/.bashrc_iCub

The reason why we use the above custom file (as opposed to the standard ~/.bashrc) is that we want to enforce the variables both during interactive and non-interactive sessions, such as commands launched via yarprun from another machine.

Additional software

OpenCV

Ubuntu packages

 sudo apt-get install libcv-dev libhighgui-dev libcvaux-dev libopencv-gpu-dev

This is the easiest way to install OpenCV, however some machines may require a custom manual compilation instead (see below).

Manual compilation

  • on most machines: download OpenCV 2.4.3 or higher, create a build directory, CMake, set WITH_CUDA=OFF, compile, set OpenCV_DIR to the path of OpenCV-x.y.z/build, for example:
export OpenCV_DIR=$code/OpenCV-2.4.3/build
  • on CUDA machines, in order to compile CUDA-enabled modules: create a build-cuda directory, CMake, set WITH_CUDA=ON, compile, set OpenCV_DIR to the path of OpenCV-x.y.z/build-cuda

YARP and iCub

If you work with the robot, use the volume shares exported from the NFS server.

In other cases:

Follow the instructions on the iCub software article. When compiling, do not use sudo make install but simply make (we have configured the PATH variable to find the latest compiled binaries, and we do not want two copies of the same thing on the system).

  • yarp CMake configuration
CMAKE_BUILD_TYPE Release
CREATE_GUIS
CREATE_LIB_MATH

// to enable 640x480@30Hz images with Bayer encoding
// install libraw1394-dev libdc1394-22-dev then enable
CREATE_OPTIONAL_CARRIERS
ENABLE_yarpcar_bayer_carrier
  • icub-main CMake configuration
CMAKE_BUILD_TYPE Release
// on servers, do http://wiki.icub.org/wiki/Installing_IPOPT then enable
ENABLE_icubmod_cartesiancontrollerclient ON
ENABLE_icubmod_cartesiancontrollerserver ON
ENABLE_icubmod_gazecontrollerclient ON
  • final configuration
  1. yarp namespace /icub
  2. in order to find the yarpserver running on iCub laptop, write 10.10.1.53 10000 into the file specified by yarp conf
  • special machines such as pc104 need different flags

CUDA

IOL

  • sudo apt-get install lua5.1 liblua5.1-dev
  • clone rFSM
