From David Fischinger via ros-users@

We are pleased to announce a new package for grasp calculation on unknown and known objects.

This package receives a point cloud representing objects and identifies where to best place the gripper. The algorithm does not require segmentation or a-priori knowledge about the objects. It has already been employed on various platforms, including a PR2 [4], a Kuka LWR [5], a Schunk arm [6] and the service robot Hobbit [7].

More details, a scientific foundation and evaluation results can be found in an IJRR journal publication from August 2015 [1], a more technical description and a simple getting started guide can be found at [2]. Code is available on GitHub [3].

Currently Indigo is supported.

Rhoeby Dynamics R2D LiDAR

| No Comments | No TrackBacks
From John Jordan President of Rhoeby Dynamics LLC

The new Rhoeby Dynamics R2D LiDAR is the smallest, lightest, lowest-cost
2D LiDAR device on the market today. It's proven capable of performing
mapping, navigation and dynamic obstacle avoidance in the indoor setting,
and comes complete with its open-source ROS driver for rapid integration
into any robotics platform.

Rhoeby.png
The device uses IR LED Time-of-Flight (not laser-based), making it a quite
novel technology. This novel approach is what enables us to achieve the
small form factor, low weight, and helps keep the cost down. All settings
are easily controlled via USB (or UART).

Video demonstrations of the LiDAR in operation can be seen here:

    http://rhoeby.com/video

In summary, the LiDAR has the following features:

    * Scan rate: up to 5 Hz, user-configurable
    * Scan range: 360 degrees, over 5 meters
    * Angular resolution: typically ~ 1.0 degree, maximum 0.36 degrees (@
1 Hz scan rate)

    * small form-factor (75 x 45 x 45 mm)
    * light-weight (< 125 g)
    * robust design (direct-drive motor)
    * no safety issues (compared to laser-based device)

We're confident that this device is well-suited to cost-sensitive
applications requiring indoor Simultaneous Localization And Mapping
(SLAM), navigation and obstacle avoidance, and will be a good fit for many
robots. The device is available now, for immediate delivery in the United
States and beyond.

2015 Metrics Report Available

| No Comments | No TrackBacks
You can now download our 2015 ROS Metrics report from: http://download.ros.org/downloads/metrics/metrics-report-2015-07.pdf 

It's the 5th edition of the report. Links to all of them can be found at: http://wiki.ros.org/Metrics

One metric which stood out to me how strong the adoption of Indigo has been. Over half our users are now using the LTS release. 

And all of these numbers do not count the any statistics for mirrors either private or public of which we've seen an increase in availability. http://wiki.ros.org/Mirrors

Demonstrating the challenge of understanding metrics, the downward change in download volume reflects the more stable core packages. During the sample period there were fewer core releases. Including no catkin, ros, or ros_comm releases in July 2015 versus one or more of each of those in July 2014.

Postdoctoral Position

Polarimetric Vision Applied to Robotics Navigation

Position details:
• Starting date: January 2016
• Duration: 12 months renewable
• Salary: around 2000 euros/month net
• Location: Le2i UMR CNRS 6306 - Le Creusot (France)

Context:
The ability of robots to move and navigate autonomously in an unknown environment is directly related to their faculty to extract information surrounding them. Polarization information is used by many animals but remains unused in the fields of robotics. For instance, the sky produces a polarization pattern that is used by bees to orient themselves[1]. The main goal of the VIPeR (Polarimetric Vision Applied to Robotics Navigation) project is to prove by developing an experimental platform that polarization can be efficiently used for navigation tasks. This project is a two years project funded by the French National Research Agency.
The first task will consist in embedding a commercial polarimetric camera on the terrestrial vehicle (Summit XL) to illustrate the ability to avoid puddles or ice hazards on the road[2]. The polarization effect by reflection will be used since after reflection, natural light that is unpolarized becomes partially linearly polarized.
The second application will consist in embedding the polarimetric sensor on a UAV (ASTEC Pellican) to exploit the polarization properties of the scattering light. The attitude estimation task will be developed by using the polarization pattern of the sky. Indeed, depending on the sun position, the sky provides a useful compass for orientation in space and can be an efficient tool to compensate the drift that frequently appear in inertial measurement unit after a long term running[3].

Team:
Researchers involved in the project: O. Morel, D. Sidibe?, C. Demonceaux, D. Fofi, R. Seulin

Required qualifications :
• Ph.D. in Computer Vision (polarization skill is not required)
• Strong programming skill in C++ and/or Python under Linux (ROS experience would be a
plus)

Application procedure:
• Applications must be sent by email to Olivier Morel (olivier.morel@u-bourgogne.fr)
quoting "VIPeR postdoc position" in the email subject, and they must contain a motivation
letter, a CV including a list of publications, and the contact information of two referees.
• Review of applications will begin immediately and will continue until the position is filled,
but for full consideration please apply before November 1st, 2015.

| No Comments | No TrackBacks
From Edward Venator via ros-users@

Southwest Research Institute (SwRI) is pleased to announce the release of Mapviz, a graphical tool for viewing ROS data from outdoor robotic systems. Mapviz, like Rviz, uses an extensible plugin architecture to display ROS data. The Intelligent Vehicles sections at SwRI developed Mapviz as a tool for our work using ROS in automotive applications. Whereas Rviz is designed for 3D display of data from indoor robots, Mapviz is a 2D (top-down) viewer designed for use with outdoor robots. We look forward to feedback and contributions from others who find Mapviz useful.

Some Features of Mapviz:

* Tile Map background maps from OpenMapQuest (open.mapquest.com) and stamen design (http://maps.stamen.com), with Bing map support coming soon
* Multires Image backgrounds to display custom maps or backgrounds
* Robot marker(s) with custom robot image icons
* Plugins for several ROS message types:
    - sensor_msgs/Disparity
    - gps_common/GPSFix (sensor_msgs/NavSatFix support coming soon)
    - sensor_msgs/Image
    - sensor_msgs/LaserScan
    - visualization_msgs/Marker
    - nav_msgs/Odometry
    - nav_msgs/Path
    - marti_visualization_msgs/Textured Marker (a custom message type for painting image data onto the visualization)
    - TF transforms

Jerry Towler of Southwest Research Institute will give a presentation on Mapviz during Day 2 of ROSCon 2015.

If you want to use Mapviz, it is available on GitHub at http://github.com/swri-robotics/mapviz. Ubuntu Debian installers from the OSRF build farm are up in the shadow-fixed repository for Indigo (Trusty) and Jade (Trusty, Utopic, and Vivid).

New Universal Robot driver

| No Comments | No TrackBacks
From Thomas Timm Andersen:

I am glad to share my new driver for the Universal Robots: https://github.com/ThomasTimm/ur_modern_driver

 

The driver is written in c++ and is designed to replace the old driver transparently, while solving some issues, improving usability as well as enabling compatibility of ros_control.

 

The most noticeable differences for current users will be the ability to use the teach pendant while the driver is connected as well as support for the UR3 and newest firmware versions.

The driver also makes it possible to send URScript commands from ROS to the robot as well as introduces a joint speed interface for doing visual servoing with the UR robots.

 

The driver resides in its own package, so you can install it and test it out without risking your current setup. Just use the included launch files instead of the ones from urX_bringup.

 

I have also included support for ros_control for those who would like to test that out. Note that the use of ros_control will probably require some minor modifications to your existing code if you choose to incorporate this into an existing project. Whether the driver should expose the "old" action interface or be controlled via ros_control is determined by a parameter at launch time. Note that the PID controllers are not optimally tuned at this time.

 

I have tested the driver with all the newest versions of ur-sim (1.6.08725, 1.7.10857, 1.8.16941, 3.0.16471, and 3.1.18024) as well as some real robots (UR5 and UR10, both with a CB2 controller running 1.8.14035).

 

Please try it out and report any issues / incompatibilities so it hopefully can make it into Jade (or indigo?)

nimbro_network: Multi-master ROS network solution

| No Comments | No TrackBacks
From Max Schwarz via ros-users#

our group has developed a network transport solution for multi-master ROS
systems. We used it with great success in the DLR SpaceBot-Cup and the DARPA
Robotics Challenge, where our team (NimbRo Rescue) got fourth place.

Opposed to other multi-master solutions, our software is targeted for *bad*
networks, such as WiFi connections. For example, it can handle large latencies
and large packet-drop ratios without introducing further latency or dropping
messages.

The stack is now available under BSD-3 license here:

https://github.com/AIS-Bonn/nimbro_network

Some features:

 * Topic transport:
   * TCP protocol for transmission guarantee
   * UDP protocol for streaming data without transmission guarantee
   * Optional transparent BZip2 compression using libbz2
   * Experimental Forward Error Correction (FEC) for the UDP transport
   * Automatic topic discovery on the receiver side. The transmitter defines
      which topics get transferred
   * Optional rate-limiting for each topic
 * Service transport:
   * TCP protocol with minimal latency (support for TCP Fast-Open is included)
   * UDP protocol with minimum latency
 * Additional nodes/filters for transmitting the ROS log, TF tree and
   H.264-compressed camera images.
 * rqt plugins for visualization and debugging of network issues

For more details, see the included README file. If you have any questions,
please don't hesitate to ask me. We would also like to hear from you if you
end up using our software!
