RoPod/Tutorials/GAZEBO installation and interface with ROS

GAZEBO is a set of ROS packages that provide the necessary interfaces to simulate a robot in the Gazebo 3D rigid body simulator for robots. It integrates with ROS using ROS messages, services and dynamic reconfigure.

Install gazebo (versions 7.x are compatible with ROS kinetic)

curl -ssL http://get.gazebosim.org | sh

Install gazebo_ros_pkgs and some extra packages needed to run the basis ropod model

sudo apt-get install ros-kinetic-gazebo-ros-pkgs ros-kinetic-gazebo-ros-control
sudo apt install ros-kinetic-joint-state-controller
sudo apt install ros-kinetic-effort-controllers

Get familiar with ROS and with the catkin_make way of working: http://wiki.ros.org/ROS/Tutorials/InstallingandConfiguringROSEnvironment

Now we will install existing ROS and gazebo files that will allow to perform simulations of the ropod

Ensure you configured GitHub and you have downloaded the repository: See tutorial

Now you are ready to start the ropod_gazebo model plus the ROS packages to interact with it.

The first time you install the files in your computer be sure that the folders ‘build’ and ‘devel’ are removed, as well as the file src/Cmakelists.txt

Then, on the main directory level, run a cmake command to generate the executable files

catkin_make

Then source your environment variables:

source devel/setup.bash

Then, we can launch the ropod gazebo model, which is already connected with ROS

roslaunch ropod_gazebo ropod_world.launch
