NASA Frees Their Robotics Software 112

kremvax writes "It's a field day for robotics hackers everywhere, as NASA releases the first installment of their CLARAty reusable robotic software framework to the public. According to the JPL press release, these modules contain everything from math infrastructure to device drivers for common motors and cameras, and computer vision, image, and 3D processing."

      If your interest is computer vision, don't forget about OpenCV: http://www.intel.com/technology/computing/opencv/ [intel.com] - actually some algorithms in NASA's framework are taken from OpenCV.

      It's funny how things happen - just as I started researching how to calibrate cameras using only manual correspondences between images (no information about world geometry known - suggestions anyone?), NASA releases their framework... That I call luck.

The 1st distribution and usage condition says that a user cannot use the software to make a commercial product, and cannot sell it commercially. This violates FSF freedom 0 (and OSI freedom 6), and the FSF's site even specifically states:

    ``Free software'' does not mean ``non-commercial''. A free program must be available for commercial use, commercial development, and commercial distribution. Commercial development of free software is no longer unusual; such free commercial software is very important.

      I'm not worried. His 'manifesto' will probably involve reprogramming other robots to do the 3 Stooges' comedy routines.

With that in mind, I could envision a sort of android that uses a high output jumbo multicolor LED as a bindi. Intense white for low light. Infrared or ultraviolet for specialized situations. Should a fatal error occur, it could flash blue a code like some inkjet printers.

    But there does exist another large robotics library that is completely free called Player [sourceforge.net]. The project even has two complete simulators, Stage (for 2D simulation of many robots) and Gazebo (for 3D simulation of a smaller number of robots). Great project for any aspiring roboticists out there.
    • by gigne ( 990887 )
      From my tiny amount of research into the Player project there is only limited support for certain real world hardware.
      It seems to be the right thing to use if you have a mobile robot. or some kind of football-playing-robot, but for serious robotics it doesn't seem to have the full package.

        I don't believe I've actually seen anything for arms before... Then again, I've never explicitly gone looking. But I have a feeling there's probably not much since, as you said, it's more geared toward mobile robots. Here's a list of supported devices: clicky [sourceforge.net].
    • If it's simulation you want, then you should also check out the Microsoft Robotics Studio.

      http://msdn2.microsoft.com/en-us/robotics/default. aspx [microsoft.com]

      http://beta.channel9.msdn.com/Media/Microsoft-Robo tics-Tour-CCR-VPL-Simulation-Part-1/ [msdn.com]

      It pains me to praise Microsoft, but from the Channel 9 video it looks pretty impresive - especially the simulation capabilities.
    • There is a big difference between the two packages. The CLARAty software seems to offer some basic robot functionality for 'emergent behavior' which is lacking in the Player framework which seems to be only a platform for simulation and communication.

      In lamans terms, the CLARAty software provides interface for common 'bottom up' robot behaviors such as avoiding obstacles, position estimation, mapping, path planning etc. This stuff may seem trivial but is actually quite complex and having an interfaces t
      • by qw0ntum ( 831414 )
        Actually, that's what Player does. It functions as a hardware abstraction layer for all the bits and pieces of the robot (motors, sensors, etc) and gives programmers a standard interface to work with. I work on machine vision; there are others in my lab that work on multi-robot collaboration. Thankfully Player handles a lot of the type of things that you mentioned (obstacle avoidance, path planning) so we don't have to. Getting robots to show a semblance of thinking is hard enough on its own. ;)
    • Do you (or anybody) know if any of these packages deal with air flight? I'd like to build a VTOL UAV and focus on the application software rather than the flight control software.

      Yeah, I know I can buy one for $15K, but that's not as much fun. :) Plus there might be some good advantages for interoperating with the flight code.

    Let me make sure I'm crystal clear on this issue: the US public funds NASA billions of dollars over many years to play about with robots in space, and then the same public is not allowed to use the software THEY PAID FOR to create down to earth, commercial robots? Think again NASA!

  • Looking at the project site itself: http://claraty.jpl.nasa.gov/ [nasa.gov] it seems that most pages are restricted. whenever I want to see some real documentation, it's asking for creditentials.

    they even describe this in length here: http://claraty.jpl.nasa.gov/man/overview/access/in dex.php [nasa.gov]

    so it's no free software, it seems... :(
  • Some of the software comes from CMU, it seems. I wonder if anyone there has taken a crack at integrating CLARAty with Tekkotsu [cmu.edu]. Assuming that JPL has some pretty cracker-jack code,(which seems safe to me), then you could buy a used Aibo and a memory stick off ebay and suddenly have the makings of a world-class robotics lab in your living room.

    And that's pretty spiffy.

ERF makes it easy to setup experiments in robotics domains and even other domains by legoing (putting together) simple components to achieve lots of different experiments. It uses robotics sensors (+30) from Player/Stage/Gazebo and displays the experiments in 3d using opengl + fltk. Also it makes it trivia

    quad optical encoders all the way.
  • Too bad. NASA joins the sorry list of software authors (like ffmpeg), who provide cool stuff, but can't be bothered to cut releases. One has to setup and configure their YaM-Lite [nasa.gov] piece of software (a Perl-wrapper around CVS), and then use that to get their various software modules.

    Yes, you can ask for a slice of the code as of a certain date, but you need to know, when it was stable. You could also, presumably, ask for a certain code branch, but that is still a moving target...
