The Whole-Body Control framework developed at the Stanford Robotics and AI Lab provides advanced control for human-centered robotics and mobile manipulation. This project provides a framework for developing robot behaviors that use operational-space hierarchical task decompositions, based on the work of many contributors over many years, under the guidance of and in collaboration with Oussama Khatib: most notably Jaeheung Park, K. C. Chang, Diego Ruspini, Roy Featherstone, Bob Holmberg, François Conti, Roland Philippsen and Luis Sentis.

Download

Clone our GIT repository...

git clone git://github.com/poftwaresatent/stanford_wbc.git

...or grab a tarball from Sourceforge: the download area contains official releases.

Build

The dependencis are:

• a C++ compiler (we use GCC for development)
• CMake cross-platform build system version 2.6 (or higher)
• Eigen matrix library version 2
• Fast Light Toolkit version 1.1.x (optional but required for tutorials)

After you cloned our repos, or downloaded and unpacked a release, go into the top-level source directory and build it:

mkdir build
cd build
cmake ..
make

There are CMake variables that influence the configure step. They get passed to cmake using its -DVARIABLE=VALUE command-line syntax. Note that reasonable guesses are made according to your operating system, but if you have installed some dependencies in non-standard locations, you will have to tell CMake where to find them.

variable name	meaning	example
EIGEN2_DIR	Path where the Eigen matrix library is installed. This will end up adding several directories to the header search path: EIGEN2_DIR itself, EIGEN2_DIR/include, EIGEN2_DIR/eigen2, and EIGEN2_DIR/include/eigen2. Note that CMake will fail with an error message if it cannot find Eigen2, and you have to clear its cache before reconfiguring with a different EIGEN2_DIR setting. The easiest way to achieve that is to remove the entire build directory.	If you installed Eigen2 underneath /home/toto/eigen2, then you have to pass -DEIGEN2_DIR=/home/toto/eigen2 to the CMake command.

Test

We use the Google Testing Framework (included in the 3rdparty subdirectory). At the time of writing, we provide the following test programs. Also note that there is a runtests.sh script in the top-level project directory, which you can run from within the build directory by issuing ../runtests.sh (assuming that your build directory is one level below the top-level source directory, as implied in this README).

• Basic (very basic) tests for the TAO dynamics engine are available by running:

    ./tao/testTAO
  

• A fairly complete suite of unit tests for the joint-space dynamics model (which is built on TAO) is available by running:

    ./jspace/tests/testJspace
  

• A budding collection of semi-functioning unit tests for the operational-space control library is available by running:

    ./opspace/tests/testTask
  

• A quick test of the mechanism that builds controllers from YAML files:

    ./opspace/tests/testFactory
  

If any of these tests fail, there is a regression that should be fixed. Please let us know via our Issue Tracker or sending an email to [email protected]

Documentation

If you have Doxygen then you can generate code documentation for the various sub-projects. There is a little rundox.sh script in the jspace/doc, opspace/doc, and tao/doc subdirectories (look for the same pattern in other parts of the project as well, we might forget to update this README file when adding sub-projects and documentation).

cd /path/to/stanford_wbc/jspace/doc
./rundox
then open html/index.html in a web browser
