Pinocchio instantiates the state-of-the-art Rigid Body Algorithms for poly-articulated systems based on revisited Roy Featherstone's algorithms. Besides, Pinocchio provides the analytical derivatives of the main Rigid-Body Algorithms like the Recursive Newton-Euler Algorithm or the Articulated-Body Algorithm.

Pinocchio was first tailored for robotics applications, but it can be used in other contexts (biomechanics, computer graphics, vision, etc.). It is built upon Eigen for linear algebra and FCL for collision detection. Pinocchio comes with a Python interface for fast code prototyping, directly accessible through Conda.

Pinocchio is now at the heart of various robotics software as Crocoddyl, an open-source and efficient Differential Dynamic Programming solver for robotics, the Stack-of-Tasks, an open-source and versatile hierarchical controller framework or the Humanoid Path Planner, open-source software for Motion and Manipulation Planning.

If you want to learn more about Pinocchio internal behaviors and main features, we invite you to read the related paper and the online documentation.

If you want to dive into Pinocchio directly, only one single line is sufficient (assuming you have Conda):

conda install pinocchio -c conda-forge

or via pip (currently only available on Linux):

pip install pin

Pinocchio main features

Pinocchio is fast:

• C++ template library,
• cache friendly,
• automatic code generation support is available via CppADCodeGen.

Pinocchio is versatile, implementing basic and more advanced rigid body dynamics algorithms:

• forward kinematics and its analytical derivatives,
• forward/inverse dynamics and their analytical derivatives,
• centroidal dynamics and its analytical derivatives,
• support multiple precision arithmetic via Boost.Multiprecision or any similar framework,
• computations of kinematic and dynamic regressors for system identification and more,
• and much more with the support of modern and open-source Automatic Differentiation frameworks like CppAD or CasADi.

Pinocchio is flexible:

• header only,
• C++ 98/03/11/14/17/20 compliant.

Pinocchio is extensible. Pinocchio is multi-thread friendly. Pinocchio is reliable and extensively tested (unit-tests, simulations, and real-world robotics applications). Pinocchio is supported and tested on Windows, Mac OS X, Unix, and Linux (see build status here).

Documentation

The online Pinocchio documentation of the last release is available here. A cheat sheet pdf with the main functions and algorithms can be found here.

Examples

We provide some basic examples of using Pinocchio in Python in the examples directory. Additional examples introducing Pinocchio are also available in the documentation.

Tutorials

Pinocchio comes with a large bunch of tutorials aiming at introducing the basic tools for robot control. Tutorial and training documents are listed here. You can also consider the interactive Jupyter notebook set of tutorials developed by Nicolas Mansard and Yann de Mont-Marin.

Pinocchio continuous integrations

Pinocchio is constantly tested for several platforms and distributions, as reported below:

Continuous Integration
CI on ROS
CI on Linux via APT
CI on OSX via Conda
CI on Windows via Conda
CI on Linux via Robotpkg

Performances

Pinocchio exploits, at best, the sparsity induced by the kinematic tree of robotics systems. Thanks to modern programming language paradigms, Pinocchio can unroll most of the computations directly at compile time, allowing to achieve impressive performances for a large range of robots, as illustrated by the plot below, obtained on a standard laptop equipped with an Intel Core i7 CPU @ 2.4 GHz.

For other benchmarks, and mainly the capacity of Pinocchio to exploit, at best, your CPU capacities using advanced code generation techniques, we refer to the technical paper. In addition, the introspection may also help you to understand and compare the performances of the modern rigid body dynamics libraries.

Ongoing developments

If you want to follow the current developments, you can directly refer to the devel branch. The master branch only contains the latest release. Any new Pull Request should then be submitted on the devel branch.

Installation

Pinocchio can be easily installed on various Linux (Ubuntu, Fedora, etc.) and Unix distributions (Mac OS X, BSD, etc.). Please refer to the installation procedure.

If you only need the Python bindings of Pinocchio, you may prefer to install it through Conda. Please follow the procedure described here.

ROS

Pinocchio is also deployed on ROS. You may follow its deployment status below. If you're interested in using Pinocchio on systems and/or with packages that integrate with the ROS ecosystem, we recommend the installation of Pinocchio via the binaries distributed via the ROS PPA. Here, you can install Pinocchio using sudo apt install ros-$ROS_DISTRO-pinocchio. This installs Pinocchio with HPP-FCL support and with Python bindings. You can then depend on Pinocchio in your package.xml config (<depend>pinocchio</depend>) and include it via CMake (find_package(pinocchio REQUIRED)) -- we include support and hooks to discover the package for both ROS1 and ROS2. An example can be found here. Please note that we always advise including the pinocchio/fwd.hpp header as the first include to avoid compilation errors from differing Boost-variant sizes.

ROS1			ROS2
Melodic			Foxy
Noetic			Galactic
			Humble
			Rolling

Visualization

Pinocchio provides support for many open-source and free visualizers:

• Gepetto Viewer: a C++ viewer based on OpenSceneGraph with Python bindings and Blender export. See here for a C++ example on mixing Pinocchio and Gepetto Viewer.
• Meshcat: supporting visualization in Python and which can be embedded inside any browser.
• Panda3d: supporting visualization in Python and which can be embedded inside any browser.
• RViz: supporting visualization in Python and which can interact with other ROS packages.

Many external viewers can also be integrated. See the example here for more information.

This release is directly accessible as a Debian package. Please see https://github.com/stack-of-tasks/pinocchio/wiki/installation for further details.

New

• The Python bindings are aligned and free of unnecessary allocations
• Add documentation option which allows to not install the documentation
• Introduces container::aligned_vector to automatically create an std::vector with specific aligned allocator

1.2.0 - 2016-09-29

Summary

The main modifications concern the update of the code to comply with the Humanoid Path Planner (HPP).

This release is directly accessible as a Debian package. Please see https://github.com/stack-of-tasks/pinocchio/wiki/installation for further details.

New Features

• Add Joint{Model,Data} classes based on Joint{Model,Data}Base and Joint{Model,Data}Variant. Those classes call directly the visitors and make Variant accessible throw methods
• Add partial Joint{Model,Data}Composite. They allow a stack of joints without adding any Inertia.
• Increase Frame class. Frames can be of several types (BODY, JOINT, SENSOR, etc) and reflect the robot tree as it appears in the URDF conventions. Frames have two attributes: parent which the direct Joint parent in the Joint tree, previousFrame which correspond to the parent Frame in the tree of Frames).
• Adding Python parser which is able to read models written in Python.
• Add algo checker to check the validity of a model.
• Improve documentation.

API modifications

• Model has some methods deprecated. The default name has been removed.
• The Geometry classes have been updated and several methods have been set to deprecated. They now use Frames as parent instead of Joint directly: a Geometry is now supported by a BODY.
• Add active collision pair flags in GeomData which define the active collision pairs.
• Unify naming conventions (nframes, njoints, etc).

Fixes

• The UDRF parser can now deal with more complex topologies. It properly handles the stack of geometries for each BODY.
• Improve packaging mainly around the Python part.

  • One can integrate a configuration at a constant velocity during a unit time
  • One can differentiate two configurations (i.e compute the velocity that must be integrated during a unit time to go from first configuration to the other )
  • One can interpolate between two configurations
  • One cancompute the distance between two configurations ( such as dist = norm ( difference) )
  • One can shoot a configuration uniformly sampled between specified limits

• Add unaligned prismatic joint
• Add geometry through Flexible Collision Library (hpp-fcl)
  • Add dedicated structs to handle geometry. GeometryModel (list of geometry objects and its relation wrt kinematic model) and GeometryData
  • When parsing urdf, meshes can be read from collada files and handled in Pinocchio
