The document provides an overview of ROS (Robot Operating System), describing it as an open-source, meta-operating system that facilitates robotic development through tools and libraries across multiple platforms. It details its history, main features, advantages, and disadvantages, emphasizing the open community and integration approach while also noting challenges such as limited support for Windows and real-time applications. Additionally, it highlights its widespread use in research and development, with numerous documented packages and federated repositories.

- 3. Contents ● Overview ● ROS Principles ● ROS History ● Applications ● Community and Software Federation ● Pros and Cons
- 4. ROS Overview “ROS is an open-source, meta-operating system for your robot. It provides the services you would expect from an operating system, including hardware abstraction, low-level device control, implementation of commonly-used functionality, message- passing between processes, and package management. It also provides tools and libraries for obtaining, building, writing, and running code across multiple computers” ● As technology it can be sen as: ● Robotic Development Platform ● Integration Software Framework for complex robotics systems ● Even Further “It is a initiative or to promote Robotics” ● Technology ● Conveys and Data Standardization ● Open Community –
- 5. ROS Overview (II) - Target
- 6. ROS Overview (III) - Principles ● Software Integration over Development ● Open Source ● Federation of development groups ● Online Community ● Homogeneous and unified documentation (Wiki) ● Social Networks and Mailing lists ● Scientific Approach (promoting research) ● Multiple Product Vision: Research, Academic & Market (service robotics, ¿industrial?)
- 7. ROS Overview (III) Main Features ● Distributed Components ● Main operative System: Linux, MacOS, (low support for windows) ● Programming Languages ● High Support for C++, python ● Lower Support Lisp, Java, Octave, others, ● Platforms: X86 y ARM ● Integrating popular packages: OpenCV, Eigen, Bullet, OROCOS (KDL, BFL), OpenSLAM, OpenRave, Stage and Gazebo, PCL, ¿¿MRPT??
- 9. The PR2 Robot ● Fold Towels ● Open Doors ● Opening Drawers ● Fetch Beers ● Plug In ● Recycling trash ● Play Hannoy Towers ● Cart Pushing
- 10. ROS History (I) Background ● Willow Garage ● Origin - Stanford University and Research Institute ● Spin-off ● Silicon – Valley Area ● Some Researchers ● Gary Bradski ● Kurt Konolige ● Brian P. Gerkey ● Radu Bogdan Rusu
- 11. ROS History (II) - Evolution Gracias por los contenidos Creative Commons de la web de ROS y de las transparencias creadas por "Radu Bogdan Rusu" para el evento: "
- 12. Robotic Software Repository Federation Stats (March 2012): ● 2363+ Documented Packages ● 100+ Federated Repositories (90+ Institutions) ● Some of them: ● CMU, TUM, MIT, PENN ... ● Unified Wiki and Documentation ● Autogenerated metainformation
- 14. Examples of Package Contents ● Meta Information (manifest) ● Components (Nodes or launch) ● Libraries ● Tools (every kind) ● Datasets ● Third Party Adapters ● Message Definitions ● Service Definitions
- 15. Advantages ● For developers and research groups: visibility ● Many people know how to use your packages ● Focus effort on research → don't reinvent the wheel ● Learn robotics by example ● Checking others code ● Reading others doc ● Promotes conveys, methodologies for general robotic software development
- 16. Disadvantages Change the development philosophy: ● ● Forget the “reinvent the wheel” - go to The Integration Paradigm ● But The integration cost is not zero –Read packages documentation –Check third party code ●In Spite of everything → Non-Uniform development methodologies between packages ●Too Linux system focused (little support for windows or RT systems) ●Not very good for real time applications (custom solutions needed) ●Several package alternatives for the same development targe t ●You have to learn a lot of usefulness stuff for very single projects
