iDynTree 1.0.3 (2020-04-01)

iDynTree 1.0.3 Release Notes

Fixed

• Fixed configuration and compilation with Assimp >= 5.0.0 (#661).
• Fixed runtime errors of the MATLAB bindings on Windows and compatibility with MATLAB 2020a (#664).

iDynTree 1.0.2 (2020-02-21)

iDynTree 1.0.2 Release Notes

Fixed

• Remove spurious inclusion of Eigen headers in ExtendedKalmanFilter.h public header, that could create probles when using that header in a downstream project that does not use Eigen (#639).
• Added find_dependency(OsqpEigen) and find_dependency(LibXml2) when iDynTree is compiled as a static library, fixing the use of iDynTree on Windows (#642).

Changed

• To reduce the possible unexpected problems, the automatic set of the IDYNTREE_USES_<pkg> CMake variable when the <pkg> CMake package is available in the system has been removed for Irrlicht and WORHP, as it was already disabled for ASSIMP and ALGLIB (#642). To use this dependencies it is now compulsory to set manually the IDYNTREE_USES_<pkg> variable to ON.

iDynTree 1.0.1 (2020-01-14)

iDynTree 1.0.1 Release Notes

This is a patch release of iDynTree 1.0, that fixes a regression that caused all the project that used the CMake command find_package(iDynTree <version>) to fail.

Detailed ChangeLog

Fixed

• Change CMake version compatibility from SameMajorVersion to AnyNewerVersion, as API breakage between major version will be limited, and to avoid breaking the compatibility of any downstream project that request a minimum version of iDynTree as in find_package(iDynTree 0.11 REQUIRED) (#629).

iDynTree 1.0.0 (2020-01-14)

iDynTree 1.0.0 Release Notes

This is the first major release of iDynTree, and from now on iDynTree will adheres to Semantic Versioning, meaning that from now on all releases of the iDynTree 1.x series will be API and ABI backward compatible.

In particular, iDynTree 2.0 will remove support for parts of iDynTree that have been deprecated for a long time such as anything that is enabled by the IDYNTREE_ENABLE_KDL CMake option, the iDynTree::DynamicsComputations class and the semantics support.

Release Highlights

Some major additions to the library with respect to iDynTree 0.11 are:

• Several attitude estimation algorithms were added in the iDynTree estimation library.
• Support for exporting iDynTree::Model as URDF files as been added, via the the iDynTree::ModelExporter class.
• Support for using OSQP as a QP solver been added in the iDynTree optimalcontrol library.
• The iDynTree::ModelLoader class has been modified to ensure that URDF models of serial robots load the joint in "normalized order", i.e. having joint closer to the fixed base come before joints that are closer to the end effector.

For more details on these and the other changes of iDynTree 1.0, check the "Detailed ChangeLog" section at the end of this release notes.

Detailed ChangeLog

Added

• Added method to compute the inverse dynamics inertial parameters regressor in KinDynComputations ( #480 ).
  KinDynComputations finally reached feature parity with respect to DynamicsComputations, that will finally be removed in one of the future iDynTree feature releases.
• Added method to return the convex hull of the constraint on the projection of the center of mass (#478).
• Added objects to deal with linear optimal control problems in the optimalcontrol library.
• Added OSQP interface via osqp-eigen in the optimalcontrol library.
• Fixed bugs in MultipleShooting solver in the optimalcontrol library.
• Added few lines of documentation in the optimalcontrol library.
• Added interface for ALGLIB and WORHP in the optimalcontrol library.
• Multiple shooting solvers can use hessians of costs and constraints in the optimalcontrol library.
• Taking into account also the sparsity pattern of constraints and dynamical system (both in jacobians and hessians) in the optimalcontrol library.
• Added visualization of vectors in the visualization library.
• Added a SolidShape helper library. This library is part of iDynTree, and is meant
  to contain all the algorithms that use in some form the visual and collision geometries of the model,
  and so they depend on the Assimp library to load meshes.
• Added an helper function that provides rough estimates of the inertial parameters (mass, first moments of mass,
  3d inertia matrix elements) of a robot given the total mass of the robot, and its collisions shapes. While the estimates
  provided are quite rough, they can be quite useful at least to provide an expected order of magnitude of the parameters,
  to normalize errors or as initial points of a nonlinear optimization procedure.
• Added attitude estimator interface to estimate the orientation of an IMU, given the IMU measurements (#516).
• Added DiscreteExtendedKalmanFilterHelper base class (#516).
• Added AttitudeMahonyFilter implementation of an explicit formulation of passive complementary filter over quaternion groups (#516).
• Added AttitudeQuaternionEKF implementation (#516).
• Added getWorldFrameTransform implementation in SimpleLeggedOdometry class
• Added a new version of changeFixedFrame in SimpleLeggedOdometryclass. This can be used to set a desired homogeneous transformation for the fixed frame
• Added bindings for AttitudeMahonyFilter, AttitudeQuaternionEKF, DiscreteExtendedKalmanFilterHelper (#522)
• Added basic tests for the Attitude Estimator classes (#522)
• Added DiscreteKalmanFilterHelper class for an implementation of a discrete, linear time-invariant Kalman Filter (#559)
• Added dynamic reset functionality to DiscreteExtendedKalmanFilterHelper class (#553)
• Added high-level Matlab/Octave wrappers of the iDyntree bindings (#530)
• Added bindings for the class Span with the name DynamicSpan (#522)
• Implement RPYRightTrivializedDerivativeRateOfChange() and RPYRightTrivializedDerivativeInverseRateOfChange() into Rotation class
• Implement left Jacobian and left Jacobian inverse of SO(3) in Rotation class (#562)
• Add nameIsValid attribute to iDynTree::SolidShape class.
• Add operator[] method to iDynTree::VectorDynSize (#596)
• Add operator[] method to iDynTree::VectorFixSize (#596)
• Implement getTotalMass() method for Model class
• Enable the installation of the ModelTestUtils.h file (#607)
• Added iDynTree::ModelExporter class to export iDynTree::Model instances to URDF files (#554).
• Added support in the URDF parser to correctly parse the optional name parameter of visual and collision elements.
• Added iDynTree::ModelCalibrationHelper to simplify loading a model from file, update its inertial parameters and exporting again to file (#576).
• In yarprobotstatepublisher, add tf-prefix and jointstates-topic options for the tf prefixes and ROS topic.

• In yarprobotstatepublisher, add reduced-model optional parameter to stream only the link transformations to transform server. By default, tranformations from all the frames are streamed to the transform server.

Changed

• The changelog has been migrated to the format described in https://keepachangelog.com/en/1.0.0/ .
• If the IDYNTREE_USES_YARP option is enabled, the minimum required version of YARP is 3.3 .
• The CMake config files are now installed in ${CMAKE_INSTALL_PREFIX}/lib/cmake/iDynTree also in Windows.
• Updated iDynTree::ModelLoader class to load by default models with normalized joint ordering (#491).
• In yarprobotstatepublisher the model joint positions values are initialized to zero and the joint positions values are updadted in run time if the values are available in ROS topic given through jointstates-topic parameter.
• In yarprobotstatepublisher, joint size check between model joints and joints in ROS topic given through jointstates-topic parameter have been removed.

Deprecated

• All the classes and methods that end in Semantics are deprecated, and will be removed in iDynTree 2.0, see #622 for more info.
• The CMake option IDYNTREE_USES_KDL and all the classes available when enabling it are deprecated, and will be removed in iDynTree 2.0 .
• In yarprobotstatepublisher, the robot option is deprecated, and replaced by name-prefix.

Fixed

• Fixed missing DOF_ACCELLERATION data in dynamic variable cache ordering
  (#587)
• Fixed compatibility of Span with SWIG bindings compilation (#522)
• Fixed implementation of Transform::log() method (#562)
• Fixed implementation of SpatialMotionVector::exp() method (#562)

iDynTree 0.11.2 (2019-12-12)

iDynTree 0.11.2 Release Notes

Unless noted otherwise, the changes in this patch release were introduced in Pull Request #482 .

Bug Fixes

• Fixed cache invalidation bug in the getFrameBiasAcc method of KinDynComputations. The internal
  cache used by getBiasAcc was never updated even if the method setRobotState was called, so the
  getFrameBiasAcc method always returned the bias acceleration corresponding to the first call to setRobotState.
• Fixed getBiasAcc method in KinDynComputations to take into account the effect of non-zero and non-parallel
  linear and angular base velocity, described in #370 .
• Fixed compilation on 32-bit Windows ( #506 )
• Fixed a URDF parser regression introduced in iDynTree 0.11 for which collision geometries were also loaded as visual geometries, and viceversa (#497, #559).
• Fixed a URDF parser regression introduced in iDynTree 0.11 for which geometry elements without origin tag were not correctly parsed (#496, #564).

New features

• The getFrameAcc method that returns the acceleration of a frame was added to the KinDynComputations class.
  As this method takes in input every time the robot acceleration, it is computationally expensive and
  is not suitable to be used for multiple frames in a tight loop. If you need a computationally convenient
  method to access frame accelerations, please open an issue.
• It is now possible to specify a non-zero bias base acceleration as input of the ForwardBiasAccKinematics function.
  This is convenient if the bias acceleration that is being computed is the bias acceleration obtained with the
  MIXED velocity representation.

iDynTree 0.11.1 (2018-09-10)

iDynTree 0.11.1 Release Notes

Bug Fixes

• Fix a locale-dependent floating point parsing in the URDF parser (#475).
• Fix compatibility with SWIG 2 (#476).
• Fix behavior of InverseKinematics if Add***Constraint method are called multiple times (#479).

iDynTree 0.11.0 (2018-08-31)

iDynTree 0.11 Release Notes

Summary

• iDynTree now official supports the following compilers: Microsoft Visual Studio 2015/2017, GCC >= 5.3 and clang >= 3.8 .
• The C++14 standard language is now used in the project, including in the public headers.
• libxml2 is now a required dependency. Check the docs to see how to install it.
• A new URDF parser was implemented. A side effect of the new parser is that the serialization of the links and joints of models
  parsed from URDF may change. In your code, please use name string (in place of indices) to identify joints and links, or use the
  iDynTree::ModelLoader class to load a Model with the specified joint serialization.
• CMake 3.5 is now required to build iDynTree.
• This is the last release of iDynTree that supports YARP 2.3.72 . From iDynTree 0.12, the optional part of iDynTree that depends on YARP will require YARP 3.

Important Changes

core

• Improve SpatialInertia documentation ( #435 ).

sensors

• The iDynTree/Sensors/SixAxisFTSensor.h header has been deprecated in favor of the iDynTree/Sensors/SixAxisForceTorqueSensor.h.

model_io

• Added dependency on Gnome libxml2, see next bullet point.
• Added library idyntree-modelio-xml to parse generic XML files. Support for XSD validation (when parsing from file). This library requires Gnome libxml2.
• Rewritten URDF parser to use the new idyntree-modelio-xml library.
• Dropped required dependency on TinyXML1. If TinyXML is found in the system, it is possible to compile the old URDF parser that has been renamed into idyntree-modelio-urdf-legacy.

core

• Added toEigen methods for Span and added typedef for Eigen maps of vectors.
• Added some typedefs to VectorDynsize and VectorFixSize classes to enable the use of make_span with these objects.
• Added copy operator in VectorDynSize and VectorFixSize for Span<double>.

high-level

• Added method to obtain relative Jacobians sparsity pattern
• Added method to obtain free floating Jacobians sparsity pattern

inverse-kinematics

• Constraints Jacobian now exploit sparsity pattern

iDynTree 0.10.0 (2018-06-20)

iDynTree 0.10.0 Release Notes

Important Changes

• Since 0.10 release, iDynTree uses C++14 in its headers, and requires GCC >= 5 and Visual Studio >= 2015
  to compile.
• Similar to the YARP policy, any new version of iDynTree will have a consecutive minor version number.
  Development version (the one contained in the devel branch before release will be denoted with a
  patch version number greater than 100. The next minor release of iDynTree will be 0.11 .

core

• Added the iDynTree::Span class (#434), modeled after
  the C++20's std::span ( http://en.cppreference.com/w/cpp/container/span ). This class can be used to write
  methods and functions that access a contiguous sequence of objects in memory with a known length.
  This is extremly useful to make sure that iDynTree classes are easy to use regardless of which
  vector type the downstream code is using, for example if it is one of std::vector<double>,
  Eigen::VectorXd or yarp::sig::Vector .

inverse-kinematics

• Frame Constraints can now be enabled and disabled dynamically ( #389 ).

estimation

• Addition of iDynTree::SchmittTrigger, iDynTree::ContactStateMachine and iDynTree::BipedFootContactClassifier classes for performing contact state detection using Schmitt trigger based thresholding and biped foot contact classification based on an alternate contact switching pattern reasoning over contact makes used for getting primary foot in contact
  (#410 , #411 ).
• Addition of iDynTree::GravityCompensationHelpers class for computing gravity compensation torques using accelerometer measurements (#438)

optimalcontrol

• Initial improvement of the optimal control library ( #442 ). See the inline documentation of the classes for more details, or open an issue
  ( https://github.com/robotology/idyntree/issues/new ) requesting documentation on some specific aspects of the optimal control library.

iDynTree 0.8.2 (2018-06-20)

iDynTree 0.8.2 Release Notes

Bug Fixes

• In the classes devoted to the external force-torque estimation, since #343 it is possible to have external forces that are completly estimated from external sensors such as skin sensors. If in a given submodels there are no unknown due to this, the pseudoinverse should be skipped ( #443 ) .
• Fix compatibility with YARP 3.

iDynTree 0.8.1 (2017-09-26)

iDynTree 0.8.1 (2017-09-29)

Bug Fixes

• The toEigen(const SpatialMotionVector & vec) and toEigen(const SpatialForceVector & vec) inline helpers functions in the iDynTree/Core/EigenHelpers.h have been modified to return a const copy of their content.
  While this is technically an API change, it was critical because most of the other toEigen methods return an Eigen::Map object, and users
  expect to be able to use Eigen modifiers methods such as toEigen(...).setZero(). Enforcing a compilation error in this case will help to prevent subtle bugs.
  As this is an inline function, this modification does not affect iDynTree's ABI ( #378 ) .

• The CMake configuration files of the release 0.8.0 were generated with the wrong version 0.7.2.
