EusLisp now open source

| No Comments | No TrackBacks

EusLisp is now open source with a BSD license! There are over two decades of robotics research built on top of EusLisp that can now more easily be shared with other researchers. All of this is accessible to ROS users as well: the JSK lab at Tokyo University has developed a roseus package that enables use of ROS within a EusLisp environment. Many robots, including the Kawada HRP-2, Aibo, Nao, and Willow Garage PR2 are compatible with EusLisp.

EusLisp is a Lisp-based programming environment for developing robotics programs. It combines a solid modeler, visualization, geometric libraries, simulation and more into a single development environment. EusLisp was originally developed by Toshihiro Matsui at AIST in 1986 and has been heavily used by the JSK Lab at Tokyo University in their humanoid robotics research.

EusLisp is an integrated programming system for the research on intelligent robots based on Common Lisp and Object-Oriented programming. The principal subjects in the field of robotics research are sensory data processing, visual environment recognition, collision avoiding motion planning, and task planning. In either problem, three dimensional shape models of robots and environment play crucial roles. A motivation to the development of EusLisp was a demand for an extensible solid modeler that can easily be made use of from higher level symbolic processing system. Investigations into traditional solid modelers proved that the vital requirement for their implementation language was the list processing capability to represent and manage topology among model components. Numerical computation power was also important, but locality of geometric computation suggested the provision of vector/matrix functions as built-ins would greatly ease programming.

From EusLisp Manual, Part I, EusLisp Basics, 1. Introduction

ROS C Turtle Release Candidate 1

| No Comments | No TrackBacks

sea-turtle-hires.pngROS C Turtle Release Candidate 1 has been released. With this release, nearly all of the remaining ROS stacks have reached stable release: camera_drivers, common, common_msgs, driver_common, imu_drivers, joystick_drivers, laser_drivers, pr2_simulator, sound_drivers, visualization, visualization_common. This release also includes ROS 1.1.16, which is a minor update and is the release candidate for ROS 1.2.

As this is our release candidate for C Turtle, we encourage users to try this release out and note any issues they have with this release. You can consult our release notes that we are currently assembling to assist with any integration issues.

NOTE: Debian packages are currently building and will be available soon. The new debian packages have a "version 21" suffix, e.g. ros-cturtle-ros_1.1.16-21.

Anton Rebguns of the University of Arizona has announced the release of a Videre Stereo Camera driver. NOTE: this package only works with ROS C Turtle. The announcement is below.

I'd like to announce an initial release of a driver for Videre Stereo cameras. The driver supports both STOC and non-STOC devices. Pretty much all settings can be controlled through the dynamic_reconfigure GUI, these include:

  • TF Frame
  • Processing Mode (for STOC devices)
  • Generic camera parameters (exposure, gain, brightness)
  • Stereo Processing parameters (uniqueness, texture thresholds, speckle size and range)

There are a few parameters that are present but don't currently work, like whitebalance and horopter settings. There are no tutorials yet, if people are using it and have problems just shoot me an email. I will be adding some documentation/tutorials fairly soon.

Thanks, Anton

ROS C Turtle Alpha 6 Released

| No Comments | No TrackBacks

sea-turtle-hires.pngROS C Turtle Alpha 6 has been released. This update includes ROS 1.1.15. Many new stacks reached stable release: image_common, image_pipeline, physics_ode, pr2_common, simulator_gazebo, and simulator_stage. We are getting close to our release candidate for the actual C Turtle release. As we approach this release candidate, we anticipate more rapid releases to quickly verify final code changes going into the system.

In addition to the new stable releases, several new unstable/research stacks are being included with this release, including vslam, slam_karto and graph_mapping.

NOTE: Debian packages are still building and will be available soon. The new debian packages have a "version 18" suffix, e.g. ros-cturtle-ros_1.1.15-18.

You can now use Shadow Robot hardware with ROS! Engineers at Shadow Robot have been busy building a ROS stack and have now reached their first release. This initial release includes an interface to both simulated and real hardware, which means that, whether or not you have a Shadow Dextrous Hand of your own, you can use your ROS software to see the Shadow hand move inside of ROS tools like rviz.

To get started, you should check the Shadow Robot ROS FAQ or checkout the Launchpad site.

urbi_ros.jpg

Thanks to the efforts of Gostai, Urbi and ROS are now compatible! Urbi 2.1 has just been released, and this new release includes integration with ROS and Urbiscript.

For ROS users, Urbiscript provides users a powerful scripting environment that provides features like parallelism and event-triggers for creating behavior scripts for your robots. ROS users can also use the Gostai Studio Suite, which provides a graphical IDE. Gostai has released the Urbi kernel as open source (AGPL), which contributes the growing community of open-source platform technologies for robotics.

For Urbi users, ROS provides a quickly growing library of reusable and open-source software components with a wide range of capabilities, including navigation, perception, and manipulation.

To find out more about Urbi open source, check out Urbi Forge. To get started with Urbi + ROS, you can read the Urbi manual or try their Urbi + ROS tutorial.

New College Dataset parser for ROS

| No Comments | No TrackBacks

Ivan Dryanovski of the CCNY Robotics Lab has announced a New College Data parser for ROS. The announcement is below.

Dear ROS community,

As you may know, the New College Data is a freely available dataset collected from a robot completing several loops outdoors around the New College campus in Oxford. The data includes odometry, laser scan, and visual information.

We have recently released a ROS parser for the New College Dataset. The parser reads in the .alog data files provided on the NCD website and broadcasts ROS messages in real time. The parser also broadcasts transforms between the robot's base frame and the sensor frames, as defined in the NCD paper.

Details about the package, as well as a demo video of the NCD data being played back in rviz, are available here:

We hope you find this useful.
