Creating a Gribot workspace
Gribot software is based on ROS, and all software project files are hosted on github. It is rather easy to create a ROS and Gribot workspace: you can find everything on the web. However, to simplify the live of readers, we are enumerating all the steps in the sections below.
Installing ROS packages
We do uses ROS Lunar under Ubuntu 16.04 and not the latest version, because not all packages have been migrated to Melodic at the time we are writing these lines. However, the goal is to go for the newest ROS version when it is possible.
We suppose that you have a working Ubuntu 16.04 system. The first step is to install ROS: beside the fact that installation details are here, we added the steps below:
This just consists in adding the ROS repository into apt sources.list.
sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
Setup the key
Installing the key will prevent error message or ROS repository locking.
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
To install the packages, just type the following commands:
sudo apt-get update
sudo apt-get install ros-lunar-desktop-full
Some packages are not installed by default: therefore you have to add them manually:
sudo apt-get install ros-lunar-canopen-motor-node ros-lunar-canopen-master ros-lunar-canopen-402 ros-lunar-canopen-chain-node
sudo rosdep init rosdep update
This make sure the ROS environment is automatically configures each time you open s shell command.
echo "source /opt/ros/lunar/setup.bash" >> ~/.bashrc source ~/.bashrc
Installing Gribot environment
Now that ROS is installed, we need to install Gribot environment.
Create a catkin environment
Catkin environment is used to host ROS and Gribot is a package.
mkdir -p ~/catkin_ws/src cd ~/catkin_ws/src catkin_init_workspace source devel/setup.bash
You can add the last line, devel/detup.bash, at the end of your .bashrc file, with the path related to your own environment.
Installing Gribot package
The Gribot package is hosted on github.
cd ~/catkin_ws/src git clone https://github.com/guycorbaz/gribot.git
When the git repository is completely downloaded, you can buil the package.
cd ~/catkin_wx catkin_make
roslaunch gribot gribot.launch
You should now see the rviz and gazebo windows that allows you to play with Gribot.
