Call for authors for a ROS Handbook

| No Comments | No TrackBacks

From Anis Koubaa via ros-users@

I am coordinating with Springer publisher to edit a handbook on Robot Operating System. There are only a few books on ROS http://wiki.ros.org/Books which mainly represent a brief introduction to ROS and a few basic applications. This does not translate the huge amount of work being done in the community and I feel the need to have a complete reference on the topic.

The prospective handbook will cover ROS from foundations and basics to advanced research works from both academia and industry. Tutorials and research papers will both be sought. The book should cover several robotics areas including but not limited to robot navigation, UAVs, arm manipulation, multi-robot communication protocols, Web and mobile interfaces using ROS, integration of new robotic platform to ROS, computer vision applications, development of service robots using ROS, development of new libraries and packages for ROS, etc. Every book chapter should be accompanied with a working code to be put later in a common repository for the readers.

To express your interest to the handbook and your intention of a chapter proposal, I would like to invite you fill in the following form. The proposed chapters are just considered as an initial expression of interest and will be included in the handbook proposal. It does not mean any kind of commitment for the author at this stage. An official call for chapters with instructions and deadline will be announced soon.

Thank you and look forward to receive your feedback,

Anis

NavVis presents new large scale mapping technology: The impressive shipping exhibition at Deutsches Museum can now be explored online and in 3D.

NavVis utilizes a trolley that's equipped with three laser scanners and six cameras. As a human operator wheels that trolley through the area to be mapped, the scanners record the horizontal and vertical dimensions of the hallway while the cameras record panoramas. The software framework is based on ROS, which allowed for a very modular design, as Suat Gedikli, Chief Software Architect at NavVis, says. One of the main advantages of their mapping device is its efficiency: In contrast to Google's mapping trolley, the operator does not have to crouch to move out of the field of view of the panoramic camera. With the patented NavVis camera head, the six cameras are assembled in a way such that the trolley operator is in their blind spot and therefore not visible. Hence 360-degree panoramas can be continuously recorded while moving the trolley.

The start-up recently teamed up with Deutsches Museum to digitize their impressive shipping exhibitions, which were mapped in less than one hour. The result is a 3D map of the exhibition, overlaid with photos of every square inch of all the surfaces.

Similar to Google Street View, their HTML5 based IndoorViewer allows people to virtually explore the museum online. Additionally, administrators can add content like text, images, video to various points on the map, which can then be accessed by users. This interactive feature also lets users do things like obtaining measurements between different points in the building (which is important for architects and in construction site monitoring applications).

NavVis, which was only founded in May of last year, is focused on public-oriented showcases and business-to-business applications. Felix Reinshagen, co-founder and managing director: "As the first step, our application is aimed at companies in the building management segment that are confronted with challenges such as documentation, inventory, path-finding and task management. We make our hardware, software and service available to them so that they can have their building and industrial plants digitized while handling the usage of their data according to their own requirements. An area the size of the Deutsches Museum is mapped and posted online within three working days for a four-figure amount."

From Paul Hvass, via ros-users@

Robotics and automation systems are increasingly reliant on both 2D and 3D imaging systems to provide both perception and pose estimation. Calibration of these camera/robot systems is necessary, time consuming, and often a poorly executed process for registering image data to the physical world. SwRI is continuing to develop the industrial calibration library to provide tools for state-of-the-art calibration with the goal to provide reliably accurate results for non-expert users. Using the library, system designers may script a series of observations that ensure sufficient diversity of data to guarantee system accuracy. Often interfaces to motion devices such as robots may be included to fully automate the calibration procedure.

More information can be found on the ROS-I blog post.

Dear ROS community,

I'm pleased to announce http://wiki.ros.org/arni - a collection of tools for Advanced ROS Network Introspection.
From the wiki page:
"Advanced ROS Network Introspection (ARNI) extends the /statistics
features introduced with Indigo and completes the collected data with
measurements about the hosts and nodes participating in the network.
These are gathered from an extra node that has to run on each host
machine. All statistics or metadata can be compared against a set of
reference values using the monitoring_node. The rated statistics allow
to run optional countermeasures when a deviation from the reference is
detected, in order to remedy the fault or at least bring the system in a
safe state."

No modification of existing nodes is required in order to use the
monitoring features. Therefore, the barrier of entry is very low:
- See the arni tutorial
or
- git clone https://github.com/ROS-PSE/arni into your catkin_ws
- roslaunch arni_core init_params.launch
- start all your other nodes
- rosrun rqt_gui rqt_gui
- Plugins -> Introspection -> Arni-Detail
  (Click on an item (host, node, topic or connection) in the tree view
  to get more details and graphs in the other widget)
- Enjoy out of the box distributed metadata-based monitoring

If you want to use the more advanced features in your own ROS network,
see the documentation on how to write "specifications" and "constraints".

The documentation can be found in the wiki including the tutorials (http://wiki.ros.org/arni/Tutorials).

Please give feedback and report any bugs found.


Many thanks to my students that worked hard on this:
Matthias Hadlich, Matthias Klatte, Sebastian Kneipp, Alex Weber, Micha Wetzel

Groovy Galapagos EOL Complete

| No Comments | No TrackBacks
As we have have now released indigo and are looking forward to Jade, it is time to retire Groovy. 

Groovy was first officially released at the end of 2012, but work toward the release had been started in early 2012.[1] During it's life cycle Groovy almost double the number of packages released reaching a maximum of 900. 

Reviewing the history of the rosdistro repository which contains the release metadata reveals that there was 2912 commits from 127 contributors over the history of the Groovy release. This represents the maintainers making the releases and does not count the many more contributors to the source code of the individual packages. There were commits on 612 different days over the 794 days tracked in this repository. This means on average there were releases of groovy packages more than 5 days per week. For a quick visualization of the activity on the repository we've put together a rendering of commits to the groovy subdirectory:These statistics only count catkin based releases, not the 178 rosbuild packages indexed separately.) 

ROS Groovy Galapagos Rosdistro Git Activity from OSRF on Vimeo.




As you may have already noticed, last week we disabled all the groovy jobs on the farm. We have kept them there for reference but do not intend to reenable them. Along those same lines, we can accept pull-requests to keep source builds working on groovy(such as  if a repository is relocated to a new host), but cannot accept pull-requests for new groovy releases. 

As always we'd like to pay trubute to the hundreds of people who put the time in to make groovy happen. It would not have happened without your efforts.

Amazon Picking Challenge @ ICRA 2015

Greetings colleagues! We are excited to announce a new manipulation contest to be held at ICRA in May 2015 (http://icra2015.org) in Seattle, WA, USA.

This may be of particular interest to the ROS community since we are encouraging researchers to push their new developments into the open-source domain (as a requirement to be eligible for the available travel support and contest prizes). We hope this leads to the contribution of new and interesting work within ROS.

------------------

Amazon is able to quickly package and ship millions of items to customers from a network of fulfillment centers all over the globe. This wouldn't be possible without leveraging cutting-edge advances in technology. Amazon's automated warehouses are successful at removing much of the walking and searching for items within a warehouse. However, commercially viable automated picking in unstructured environments still remains a difficult challenge. In order to spur the advancement of this fundamental technology we are excited to be organizing the first Amazon Picking Challenge at ICRA 2015. It is our goal to strengthen the ties between the industrial and academic robotic communities and promote shared and open solutions to some of the big problems in unstructured automation. To this end the contest will be awarding travel grants to ICRA 2015, practice equipment, and a large prize pool for the competition winners.

This competition will challenge entrants to build their own robot hardware and software that can attempt simplified versions of the general task of picking items from shelves. The robots will be presented with a stationary lightly populated inventory shelf and be asked to pick a subset of the products and put them on a table. The challenge combines object recognition, pose recognition, grasp planning, compliant manipulation, motion planning, task planning, task execution, and error detection and recovery. The robots will be scored by how many items are picked in a fixed amount of time, with $26,000 in prizes being awarded. Participants will be encouraged to share and disseminate their approach to improve future challenge results and industrial implementations.
