RBDL - Rigid Body Dynamics Library Copyright (c) 2011-2013 Martin Felis email@example.com
The RBDL is a highly efficient C++ library that contains some essential rigid body dynamics algorithms such as the Articulated Body Algorithm (ABA) for forward dynamics, Newton-Euler Algorithm for inverse dynamics and the Composite Rigid Body Algorithm (CRBA) for the efficient computation of the joint space inertia matrix. It further contains code for forward and inverse kinematics and handling of external constraints such as contacts and collisions.
The code was written by Martin Felis firstname.lastname@example.org and tightly follows the notation used in Roy Featherstone''s book "Rigid Body Dynamics Algorithm".
- 20 February 2013: removed too specialized RigidBodyDynamics::Body constructor (API version 1.1.0)
- 29 January 2013: added code for api_version_checking. Current API version is 1.0.0.
- 11 January 2013: removed Eigen3 sources and relying on an already installed Eigen3 library. Optionally RBDL can be used with the included but slower SimpleMath library.
- 18 June 2012: added support of luamodel_introduction
- 01 June 2012: added support of joint_models_fixed
- 14 May 2012: fixed Body constructor as reported by Maxime Reis
- 04 April 2012: added benchmark tool for CRBA
- 01 March 2012: added multi degree of freedom joint_models
- 06 Februry 2012: restructured constraint handling using RigidBodyDynamics::ConstraintSet
- 24 January 2012: implemented compact and fast representation of RigidBodyDynamics::Math::SpatialTransform
The documentation is contained in the code and can be extracted with the tool doxygen.
To create the documentation simply run
which will generate the documentation in the subdirectory ./doc/html. The main page will then be located in ./doc/html/index.html.
An online version of the generated documentation can be found at http://rbdl.bitbucket.org.

Building and Installation
The RBDL is built using CMake (http://www.cmake.org). To compile the library in a separate directory in Release mode use:
mkdir build cd build/ cmake -D CMAKE_BUILD_TYPE=Release ../ make
For optimal performance it is highly recommended to install the Eigen3
linear algebra library from
http://eigen.tuxfamily.org. RBDL also
comes with a simple, albeit much slower math library (SimpleMath) that can
be used by enabling
cmake -D RBDL_USE_SIMPLE_MATH=TRUE ../
The library is published under the very permissive zlib free software license which should allow you to use the software wherever you need.
