Mekabot M3 Installation instructions

This wiki describes the full installation of m3 software to control/simulate the Meka robot at Ensta ParisTech. This installation supports 3 versions, depending on your needs :

Only the M3 python API for development
Real-time M3 (c++ and python) for development and simulation
Real-time M3 for Meka's real-time PC (same as above but with EtherCAT component)

OS Tested	Status	Notes
Ubuntu 12.04 x86	OK	w ROS Hydro
Ubuntu 12.04 x64	OK	w ROS Hydro
Ubuntu 13.10 x86	OK	w ROS Indigo
Ubuntu 14.04 x64	OK	w ROS Indigo/MoveIt!

Current version on the Meka : Ubuntu 14.04LTS on kernel 3.10.32, rtai4.0 (magma branch from the cvs), Igh EtherCAT master 1.5.2, ROS Indigo+MoveIt!

Build Status

Ubuntu 12.04 - 14.04 (x86/x64) w/ ROS Hydro/Indigo

Prerequisites

Necessary

sudo apt-get install cmake git libeigen3-dev libprotobuf-dev protobuf-compiler gnuplot-x11 libboost-dev python-dev python-protobuf python-matplotlib python-yaml python-gnuplot python-scipy python-sip-dev python-sip sip-dev swig python-pandas python-sympy python-nose python-numpy openssh-server openssh-client

Nice to have to maybe compile a kernel later

sudo apt-get install libqt4-dev moc g++ libncurses5-dev kernel-package gcc-multilib libc6-dev libtool automake

Note : if you only want the python interface, jump to the "install Mekabot" section.

The RTAI-patched kernel (x64)

Download

The recommended way is to compile your own kernel, but you can try this one if you like :

# Get the Rtai4.0 patched kernel headers
https://drive.google.com/open?id=0ByavWcVYC8lWWExlSlBLMjRaSW8

# Get the Rtai4.0 patched kernel image
https://drive.google.com/open?id=0ByavWcVYC8lWdERoazdNU285V2s

It is always best to compile your own kernel

Installation

sudo dpkg -i linux-headers-3.10.32-rtwar4_3.10.32-rtwar4-10.00.Custom_amd64 linux-image-3.10.32-rtwar4_3.10.32-rtwar4-10.00.Custom_amd64

Now boot on the new kernel using grub at startup. Please note the name of the kernel.

Note : you might have to either hold sift on startup or update the grub config to boot on the rtai patched kernel:

sudo nano /etc/defaults/grub

(Recommended) Configure your kernel boot options

sudo nano /etc/default/grub
# Then edit the following line: 
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
# To :
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash lapic=notscdeadline hpet=disable i915.i915_enable_rc6=0 i915.powersave=0 intel_idle.max_cstate=0 processor.max_cstate=0 idle=poll"

## Explanation
# lapic=notscdeadline : usefull for i5 and i7 processors, reduces latency by a factor of 10 on the meka-mob
# hpet=disable : rtai does not like hpet, so disable it to make sure it never uses it (it should not). Not mandatory as rtai is smart enough to not use it.
# i915.i915_enable_rc6=0 : disable deep sleep for processor, we want max power.
# intel_idle.max_cstate=0, processor.max_cstate=0 :  same as above
# i915.powersave=0 : disable the power management, i.e less interruptions.
# idle=poll : Poll forces a polling idle loop that can slightly improve the performance of waking up a idle CPU, but will use a lot of power and make the system run hot. Set CPU fan to maximum all the time (in bios). 

# Theses option will provide you ~300 nanosecond latencies (which is very low, so, very good).



# Then apply the update:
sudo update-grub
sudo reboot

RTAI 4.0 installation

Download

sudo apt-get install automake
git clone https://github.com/ShabbyX/RTAI.git ~/RTAI

Installation

cd ~/RTAI
 ./autogen.sh
make menuconfig
# Configure the Number of cpus you have, and uncheck oneshot timer
make
sudo make install

Notes: Rtai libraries, modules headers etc should be installed in /usr/realtime/, and that makes everyone's life easier.

Know issues : On 64-bit CPUs, if an error regarding -mpreferred-cache-boundary=3 shows up, edit line 57 in /usr/src/linux/arch/x86/Makefile (where linux is your rtai patched kernel) to set this parameter to 4:

sudo gedit  /usr/src/linux/arch/x86/Makefile
# 57: KBUILD_CFLAGS += $(call cc-option,-mno-sse -mpreferred-stack-boundary=4)

Part of the explanation: http://mail.rtai.org/pipermail/rtai/2013-December/026198.html

Know issues : on 12.04 32 bits machines, rtai fails to compile (some header is missing)

sudo apt-get install gcc-multilib g++-multilib libc6-dev
sudo ln -s /usr/include/i386-linux-gnu/gnu/stubs-32.h /usr/include/gnu/stubs-32.h

Post install

Update the ld library path to find rtai:

sudo -s
echo /usr/realtime/lib/ > /etc/ld.so.conf.d/rtai.conf
exit
sudo ldconfig

Install ROS

sudo sh -c "echo 'deb http://packages.ros.org/ros/ubuntu $(lsb_release -cs) main' > /etc/apt/sources.list.d/ros-latest.list"

For Ensta people : use local repo (way faster)

sudo sh -c "echo 'deb http://fermion.ensta.fr/ros/ubuntu $(lsb_release -cs) main' > /etc/apt/sources.list.d/ros-latest.list"

If on Ubuntu < 13.10

ROS_DISTRO=hydro

If on Ubuntu > 13.10

ROS_DISTRO=indigo

ROS + MoveIt! + ROS Control

wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install ros-$ROS_DISTRO-desktop-full ros-$ROS_DISTRO-moveit-* ros-$ROS_DISTRO-ros-control ros-$ROS_DISTRO-ros-controllers python-rosinstall python-pip

You can check the ros_control implementation in the wiki.

sudo -E rosdep init
rosdep update

Openni (ROS Hydro Only)

sudo apt-get install ros-$ROS_DISTRO-openni*

Create the ROS-workspace

source /opt/ros/$ROS_DISTRO/setup.bash
## Create the ROS-workspace
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
catkin_init_workspace
cd ~/catkin_ws/
catkin_make

Install Mekabot M3

Download

git clone https://github.com/ahoarau/mekabot.git ~/mekabot
cd ~/mekabot
git submodule init
git submodule update
git submodule foreach git checkout master

Installation

Holomni PCV for the mobile base

If on Ubuntu 14.04 LTS:

sudo -E add-apt-repository ppa:hoarau-robotics/ppa
sudo apt-get update
sudo apt-get install holomni-pcv

If not :

cd ~/mekabot
cd holomni_pcv
mkdir build;cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
sudo make install

Mekabot

cd ~/mekabot
mkdir build;cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
sudo make install

Note :

Compiling in Release makes the M3 system twice as fast (Essentially due to KDL).

If you are running on real hardware, install EtherCAT first, then compile Mekabot with -DETHERCAT=1 and in release as above.

Update your bashrc

touch ~/.m3rc
echo '

echo 'source ~/.m3rc' >> ~/.bashrc
source ~/.bashrc

(Recommended) Compile Legacy shared memory ROS

cd ~/catkin_ws/src
ln -snf ~/mekabot/m3core/ros m3core_ros
ln -snf ~/mekabot/m3meka/ros m3meka_ros
cd ~/catkin_ws
catkin_make_isolated
catkin_make_isolated
catkin_make

Get time synchronization for ROS (Highly recommended for Ensta users)

sudo apt-get install ntp
sudo nano /etc/ntp.conf

Comment all the servers lines and add 'server ensta.ensta.fr'. It should look like that :

#server 0.ubuntu.pool.ntp.org
#server 1.ubuntu.pool.ntp.org
#server 2.ubuntu.pool.ntp.org
#server 3.ubuntu.pool.ntp.org
server ensta.ensta.fr

# Use Ubuntu's ntp server as a fallback (or not at ensta ;) )
server ntp.ubuntu.com

sudo service ntp restart

(OPTIONAL) Force the time to update every day (can drift after long shutdown)

sudo -s
touch /etc/cron.daily/ntpdate
echo '#!/bin/sh
ntpdate ensta.ensta.fr'>>/etc/cron.daily/ntpdate
exit
sudo chmod 755 /etc/cron.daily/ntpdate

(Recommended) Install some IDEs

Python (for most users): Eclipse + PyDev or spyder

sudo apt-get install eclipse spyder

ROS and C++ Real-time (Advanced users): Qt creator and/or Kdevelop

sudo apt-get install qtcreator 
sudo apt-get install kdevelop

(OPTIONAL) Setup robot's Pcs :

sudo -s
echo '192.168.20.117 meka-mob'>>/etc/hosts
echo '192.168.20.118 meka-moch'>>/etc/hosts
echo '192.168.20.119 meka-mud'>>/etc/hosts
exit

Configure your virtual installation

This scripts just updates the hostname in your m3_config.yml, that tells which computer is running the m3rt_server. On the meka it's meka-mob, but for vitual installations, it's your computer!

configure_robot_config_virtual.py

Run the server and visualize the robot on Rviz (virtual installation)

# run the realtime server
m3rt_server_run 
# In another terminal :
# Launch roscore, robot description, robot state publisher, joint state publisher and rviz
roslaunch meka_description m3ens_viz.launch

You're done !
