Overview

ros-Robonaut2-ISS-770x578

VIDEO: The “first human-like robot to space” went onboard the NASA STS-133 ULF-5 mission to the International Space Station “to become a permanent resident” on the orbiting spacecraft. With a pair of robotic arms and nimble hands, the humanoid robot known as Robonaut2 (R2) can “one day venture outside the station (for EVA) to help spacewalkers to make repairs or additions to the station or perform scientific work.”

“It can lift heavy objects in space. But then, since everything is weightless, anyone can.”

Why ROS?

ROS (Robotic Operating System) is the de facto standard for robot programming. It provides libraries and tools to help software developers create robot applications. It provides hardware abstraction, device drivers, libraries, visualizers, message-passing, package management, and more.

ROS was originally developed in 2007 at Stanford university’s Artificial Intelligence Laboratory. Since 2013 it is managed by OSRF (Open Source Robotics Foundation) and offered free to use under open source BSD license.

https://github.com/ros

ROS runs within Ubuntu 14.04 (not other Linux flavors).

ROS modules can be written in any language for which a client library exists (C++, Python, Java, MATLAB, etc.).

Gazebo 3D Simulator

Gazebo visually simulates (displays) what the robot does.

http://gazebosim.org

http://gazebosim.org/tutorials

  1. The Gazebo software includes a database of many robots and environments (Gazebo worlds)

      rosrun gazebo_ros gazebo

    Catkin

    Catkin is the ROS build system to generate executables, libraries, and interfaces.

    A CMake-based build system that is used to build all packages in ROS.

  2. Build the Eclipse project files with additional build flag

    § The project files will be generated in ~/catkin_ws/build

    catkin_make
  3. Setup a Project in the Eclipse IDE:

     catkin build package_name -G"Eclipse CDT4 - Unix Makefiles"
    -DCMAKE_CXX_COMPI

    Download

  4. Directly clone to your catkin workspace.

    Using a common git folder is convenient if you have multiple catkin workspaces.

  5. Open a terminal and browse to your git folder

    cd ~/gits
    
    
  6. Clone the Git repository with

     git clone https://github.com/ethzasl/ros_best_practices.git
  7. Symlink the new package to your catkin workspace

    ln -s ~/git/ros_best_practices/ ~/catkin_ws/src/

    Launch

  8. Launch files are written in XML as *.launch files

    Master

    The ROS Master manages the communication between nodes.

    Every node registers at startup with the master.

  9. Start a master with

    </strong> roscore </strong>
  10. See http://wiki.ros.org/Master

    Nodes

  11. Run a talker demo node with

     rosrun roscpp_tutorials talker
