May 2018 Archives

Looking foward to ROSCon 2018 we're highlighting presentations from last year. The ROSCon 2018 registration is currently open. As well as the Call for Proposals.

Twinkle Jain and Gene Cooperman present how they are using DMTCP to checkpoint ROS processes.

Video

Abstract

The ROS master is well-known to be a single point of failure. The DMTCP open-source package for transparent checkpoint-restart was recently extended to support checkpointrestart for the ROS master. After a failure, the ROS master is rolled back and resumed from the last checkpoint. Checkpoints can be performed as often as every few seconds. The DMTCP plugin model also allows users to add plugins that model and restart their external devices in a state equivalent to that at checkpoint. Finally, we speculate on the potential of DMTCP's distributed mode to support a global restore with appropriate plugins in the future.

From Discourse

Greetings ROS users,

Happy World Turtle Day! :turtle: [1]

I am pleased to announce that the 12th ROS distribution, Melodic Morenia [2], is now available on Ubuntu Bionic 18.04, Ubuntu Artful 17.10, and Debian Stretch. 32-bit ARM (armhf) packages are available on Bionic, and 64-bit ARM (aarch64) packages are available for Ubuntu Bionic and Debian Stretch.

To install ROS Melodic, refer to the Installation page on the Wiki:

http://wiki.ros.org/ROS/Installation

There are a couple of Release notes to be aware of while installing Melodic:

• If you installed Melodic from binaries during the beta, you'll have to remove all of your packages and reinstall them.
• There are currently no debug packages (containing the debug symbols) available for Ubuntu Bionic or Artful packages. This will be remedied a short time after the release, see https://github.com/ros-infrastructure/reprepro-updater/pull/60 for details and the fix.

Check out the Migration guide for a changelog of new features and API changes:

http://wiki.ros.org/melodic/Migration

465 packages in the ROS ecosystem are in the initial release of Melodic, compared to 2020 currently in Kinetic. You can see the released packages on the status page for Melodic:

http://repositories.ros.org/statuspage/rosmelodic_default.html

And you can compare the versions of packages in Melodic and other active ROS distributions here:

http://repositories.ros.org/statuspage/comparekinetic_melodic.html

http://repositories.ros.org/statuspage/compareindigokineticlunar_melodic.html

If there's a package missing in Melodic that you'd like to see released, please: * check if the package can be released here:

http://repositories.ros.org/statuspage/blockedreleases_melodic.html * contact the maintainers to let them know: * by opening an issue on the source repository * posting on the ROS discourse release category: https://discourse.ros.org/c/release

Even though we've made the initial Melodic release, it's never too late to add packages to Melodic (or Lunar, Kinetic, or Indigo) for upcoming syncs.

Melodic T-shirts (and hoodies) should come through in the mail this week.

We'd also like to announce the name of the next ROS distribution:

Noetic Ninjemys

Thank you to all of the maintainers and contributors who helped make this release possible. We couldn't do this without you.

Looking foward to ROSCon 2018 we're highlighting presentations from last year. The ROSCon 2018 registration is currently open. As well as the Call for Proposals.

In this talk Dirk and Mikael focus on sharing a vision of how ROS2 will be useful in different use cases.

Video

Abstract

Using a concrete use case, this talk will describe the vision of how ROS 2 users will design and implement their autonomous systems from prototype to production. It will highlight features, either available already in ROS 2 or envisioned to become available in the future, and how they can be applied toward building more capable, flexible, and robust robotic systems. While the presentation starts with a simple application, it later utilizes more advanced features like introspection and orchestration capabilities to empower the system for more complex scenarios and harden it to the point of a production-ready system.

Looking foward to ROSCon 2018 we're highlighting presentations from last year. The ROSCon 2018 registration is currently open. As well as the Call for Proposals.

The first talk at ROSCon 2017 was given by Shinpei Kato about the current state of Autoware a ROS-based open sources software platform for urban self driving mobility.

Video

Abstract

Autoware is open-source software (OSS) for urban self-driving mobility, empowered by ROS. It provides complete modules of perception, decision making, and control, which enables drive-by-wire vehicles to drive autonomously in public road environments. The current maintainer of Autoware is Tier IV, a Japanese academic startup company comprising professors and students. Automotive makers and suppliers now often use Autoware to build their research and development prototypes of self-driving mobility. Autoware has also been partly ported to ROS2. This talk will be of interest to any researchers, developers, and practitioners who are looking for opensource solution of self-driving mobility.

To kick off this series we'll start with the ROSCon Opening Remarks. Brian Gerkey welcomes everyone and Tully Foote provides some perspective on the 10 years of ROS as we approached ROS's 10th anniversary.
