From Ben Arvey via @ros-users

Hello, my name is Ben Arvey and I've been developing a set of analysis tools for ROS under the direction of Dr. Bill Smart. Our lab is giving a talk at ROSCon concerning our research, of which this is one aspect.

I'm looking for some preliminary feedback from developers. Any information about what you need in an analysis tool would be very helpful!

Here's the web app (Chrome works best):

Here's a page with some basic documentation info and suggestions for feedback:

Experimental Indigo binaries for ARM

| No Comments | No TrackBacks
From Austin Hendrix via ros-users@

I'm pleased to announce that I have experimental binary builds of ROS available for ARM and ready for wider testing.

I have builds of the ros-core and ros-base metapackages, along with PCL and the navigation stack.

Notably missing are the OpenNi drivers, rviz, moveit, and many other packages. I'm planning to work on them, but they're not currently available.

Installation instructions are available at , and the full build status is available at (green packages are built, red packages failed to build).

Just to clarify, these are builds of ROS Indigo targeted at Ubuntu Trusty (14.04) running on armhf processors

Over at Queen Mary University London, they run a postgraduate course in Media and Arts Technology, and one of the students there, Ed Burton, created this innovative performance using ROS and the RoNeX.

This is still a work in progress but here's a  teaser of Ed's work, using ROS for a beautiful project:

And here is a quick peak at his RoNeX installation:

Lasers, anyone?

We're happy to announce that SICK has donated hardware to OSRF for the ROS community to use in testing and development. We're now the proud owners of one each of the following laser scanners: TiM551, LMS111, and LMS511.

This generous donation was motivated by SICK's longstanding commitment to robotics, combined with their desire to see first-class support for their sensors in ROS. The LMS series is best known for providing reliable LiDAR data in tough conditions including the DARPA Urban Challenge and Boston Dynamics' LS3 AlphaDog. The TiM is a smaller version designed for great performance with low power consumption in indoor or outdoor environments.

The sensors are available for loan to members of the ROS community who want to use them for testing and development, and especially for improvement of the ROS drivers and associated tools. If you'd like to borrow one of these devices to try it out in your project, please let us know:

Thank you to our friends at SICK, and we look forward to even more robotics applications that are enabled by SICK sensors and ROS software!

From Manos Tsardoulias 

Dear all,

We are happy to announce that the current version of STDR Simulator is 0.2! The changes compared to the v0.1.3 follow:

  • Several bugs were fixed
  • Code was refactored
  • Lidar resources were added
  • Added support of:
    • RFID tags and Readers
    • Thermal sources / sensors
    • CO2 sources / sensors
    • Sound sources / sensors

Special thanks to Sergey Alexandrov and Scott K Logan for code contributions.

Our future plans:
  • Make the sensor measurements more realistic
  • Add simulated battery in robots
  • Detection of robots footprint via other robots' distance sensors
  • Add a simple physics engine
It would be excellent if any of you would like to contribute either by code developmentissue reporting or features request!

The STDR team.

New Package: Behavior Trees pi_trees

| No Comments | No TrackBacks
From Patrick Goebel via ros-users@

Hello ROS Fans,

I have created a ROS package implementing behavior trees called pi_trees.  It is written in Python and is modeled after the most excellent executive_smach package (though without the visualizer).  The only documentation I have so far is a PDF which was copied out of a chapter from my latest ROS book mentioned earlier on the list.

The package consists of a standalone Python module and a ROS wrapper for connecting to ROS topics, services and actions.

Hopefully someone will find the package useful.  And if anyone can find problems with the code or a better way of doing things, I'd love to hear it.

Early registration for ROSCon 2014 closes this Friday, August 15th. Register today to confirm your spot, save money, and ensure that you get a ROSCon t-shirt.

In addition, the deadline for the reduced rate rooms at the Palmer House is next Thursday, August 21st. Book your room today.
