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 iCub machines configuration/Archive for obsolete information.

Operating system installation

Ubuntu LTS, default settings and partitioning. The first user to be created must be called icub, to make the distributed setup possible: for NFS network mount, this user has to have 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.

Configure a static IP as explained in one of the following subsections, depending if the machine is a desktop or a server one.

Also, it is recommended to set up the /etc/hosts file as follows: 

10.10.1.41 icubbrain1
10.10.1.42 icubbrain2
10.10.1.50 pc104
10.10.1.51 icub-cuda
10.10.1.53 icub-laptop

You should be able to do ping icubbrain1, in addition to ping icubbrain1.visnet

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. Usually you do not need all of the following variables and settings, just a subset.
# /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 ICUBcontrib_DIR=$ROBOT_CODE/icub-contrib-common/build
export YARP_ROOT=$ROBOT_CODE/yarp
export YARP_DIR=$YARP_ROOT/build
export ICUB_ROOT=${ROBOT_CODE}/icub-main
export ICUB_DIR=${ICUB_ROOT}/build
export icub_firmware_shared_DIR=${ROBOT_CODE}/icub-firmware-shared/build
export YARP_DATA_DIRS=${YARP_DIR}/share/yarp:${ICUB_DIR}/share/iCub:${ICUBcontrib_DIR}/share/ICUBcontrib
export FIRMWARE_BIN=${ROBOT_CODE}/icub-firmware/build
export IPOPT_DIR=$ROBOT_CODE/Ipopt-3.11.9
export OpenCV_DIR=$ROBOT_CODE/opencv-2.4.9/build
#export OpenCV_DIR=$ROBOT_CODE/opencv-2.4.9/build-cuda # for opencv_gpu

# if your modules rely on icub-contrib-common (such as POETICON++), set the following:
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

# himrep, IOL, stereo-vision, SiftGPU, Lua
export SIFTGPU_DIR=~/SiftGPU    # note: SiftGPU installed outside NFS
export LIBSVMLIN_DIR=${ROBOT_CODE}/himrep/liblinear-1.91
### DO NOT REMOVE ';;;' ###
export LUA_PATH=";;;${ROBOT_CODE}/rFSM/?.lua;${ICUBcontrib_DIR}/share/ICUBcontrib/contexts/interactiveObjectsLearning/LUA/?.lua"
export LUA_CPATH=";;;$YARP_ROOT/bindings/build-lua/?.so"

export PATH=$PATH:$ICUB_DIR/bin:$YARP_DIR/bin:$ICUBcontrib_DIR/bin
export PATH=$PATH:${ROBOT_CODE}/rFSM/tools:${ICUBcontrib_DIR}/share/ICUBcontrib/contexts/interactiveObjectsLearning/LUA
export PATH=$PATH:${YARP_ROOT}/bindings/build-lua
# CUDA
export PATH=$PATH:/usr/local/cuda-6.5/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-6.5/lib64

export YARP_ROBOT_NAME=iCubLisboa01

# To enable tab completion on yarp port names
if [ -f $YARP_ROOT/scripts/yarp_completion ]; then
  source $YARP_ROOT/scripts/yarp_completion
fi
  • Then, before the following line of /etc/bash.bashrc
[ -z "$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. yarp conf 10.10.1.53 10000 (yarpserver runs on iCub laptop)
  • special machines such as pc104 need different flags

CUDA

Prerequisites

CUDA Toolkit, SDK and Examples

  • download and install NVIDIA CUDA Toolkit from http://docs.nvidia.com/cuda (not from Ubuntu packages)
  • output of successful installation:
Driver:   Installed
Toolkit:  Installed in /usr/local/cuda-6.5
Samples:  Installed in /home/icub
Please make sure that
-   PATH includes /usr/local/cuda-6.5/bin
-   LD_LIBRARY_PATH includes /usr/local/cuda-6.5/lib64, or, add /usr/local/cuda-6.5/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run the uninstall script in /usr/local/cuda-6.5/bin
To uninstall the NVIDIA Driver, run nvidia-uninstall

SiftGPU

  • download it from http://cs.unc.edu/~ccwu/siftgpu/
  • unzip it - typically in your home directory, not in the NFS shared folder
  • define export SIFTGPU_DIR=~/SiftGPU or similar in your iCub bashrc file
  • compile with make
  • if you obtain the error "/usr/local/cuda/bin/nvcc: Command not found", this can help: sudo ln -s /usr/lib/nvidia-cuda-toolkit /usr/local/cuda. See also http://askubuntu.com/questions/231503/nvcc-compiler-setup-ubuntu-12-04
  • run the test programs SimpleSIFT, MultiThreadSIFT in a real console on the machine (not via ssh)

himrep

Clone https://github.com/robotology/himrep, follow the instructions to compile liblinear, CMake, make install

IOL

  • sudo apt-get install lua5.1 liblua5.1-dev
  • clone rFSM (no need to compile anything here)

Clone https://github.com/robotology/iol, CMake, make install

stereo-vision

Clone https://github.com/robotology/stereo-vision, CMake with USE_SIFT_GPU=ON, make install

Best practices

Edit XML files locally, in /home/icub/.local/share/yarp

To install robot-specific XML files, compile icub-main (just make) then use commands like yarp-config robot --import-all (installs all files) or yarp-config robot --import iCubLisboa01 affordancesExploration.xml (installs specific files)

To install application conf/*.ini files, compile a project (e.g., icub-main, poeticon, iol) then use commands like yarp-config context --import-all (installs all files) or yarp-config context --import actionsRenderingEngine (installs the files of specific applications)
