YARP
Yet Another Robot Platform
YARP 3.0.0 (2018-06-11) Release Notes

A (partial) list of bug fixed and issues resolved in this release can be found here.

  • All YARP libraries can now be modified and distributed under the terms of the BSD-3-Clause license. See the accompanying LICENSE file for details.
  • Visual Studio 2013 is no longer supported.
  • CMake 3.5 or later is now required.
  • Optional dependency on YCM now requires version 0.8.0 or later.
  • All the functionalities deprecated before YARP 2.3.72 were removed.
  • The CREATE_DEVICE_LIBRARY_MODULES option was renamed YARP_COMPILE_DEVICE_PLUGINS and is now enabled by default.
  • The CREATE_OPTIONAL_CARRIERS option was renamed YARP_COMPILE_CARRIER_PLUGINS and is now enabled by default.
  • YARP now accepts the keyboard COMPONENTS in find_package(YARP) calls. The YARP_LIBRARIES variable contains only the libraries corresponding to the components requested in the last find_package(YARP) call. If no components are specified, the OS, sig, dev and math (only when enabled) components are searched.
  • The YARP_INCLUDE_DIRS variable is deprecated, as it is handled automatically by CMake targets.
  • The YARP_MATH_LIBRARY is deprecated. You can check for YARP_math using find_package(YARP COMPONENTS math)

YARP_conf

  • The YARP_WRAP_STL_STRING and YARP_WRAP_STL_STRING_INLINE are now always undefined, and they are now considered deprecated.

YARP_OS

  • The shmem carrier is no longer builtin inside YARP_OS and it is now a plugin.
  • The Run class was moved to the new library YARP_run
  • yarp::os::setprogname() is now deprecated.
  • yarp::os::getprogname() is now deprecated.
  • yarp::os::SystemInfo::getProcessInfo() now returns info for current process when called without arguments.
  • The methods yarp::os::Mutex::tryLock() and yarp::os::RecursiveMutex::tryLock() were deprecated in favour of try_lock().
  • ConstString is now deprecated in favour of std::string.
  • Replaced YARP_INT{8,16,32,64} with std::int{8,16,32,64}_t from cstdint
  • Use defines from cinttypes instead of YARP_INT64_FMT
  • Add yarp::conf::float{32,64,128}_t (128 only if supported)
  • Add yarp::conf::ssize_t
  • Deprecate YARP_INT{8,16,32,64} in favour of std::int{8,16,32,64}_t
  • Deprecate YARP_FLOAT{32,64} in favour of yarp::conf::float{32,64}_t
  • Deprecate YARP_INT64_FMT in favour of PRId64
  • Deprecate YARP_CONF_SSIZE_T in favour of yarp::conf::ssize_t
  • Add the following methods:
  • The following methods are not deprecated due to the large codebase where they are used, but their usage in new code is discouraged, and it is forbidden inside YARP. Anyway, all these methods are now calling the corresponding Int32 and Float64 version, but are not architecture safe, since they still accept int and double.
  • Value constructors are now explicit.
  • Thread setOptions() and setDefaultStackSize() are now deprecated and no longer doing anything.
  • The YARP_STACK_SIZE environment variable is no longer used.
  • Portable::getType() became Portable::getType() const(#1617).
  • PortWriter::getWriteType() became PortWriter::getWriteType() const(#1621).
  • PortReader::getReadType() became PortReader::getReadType() const(#1616).
  • Companion has been moved to a dedicated library (#1509). As consequences:
    • Following functions has been moved from Companion to NetworkBase: disconnectInput, poll, sendMessage, wait (wait() has been split into two new functions waitConnection() and waitPort().
    • Companion::exists() has been removed unifying its code with NetworkBase::exists().
    • readString() function has been deprecated in NetworkBase.
  • RateThread has been deprecated in favour of the new class PeriodicThread. Note that RateThread used the period in msec(int), PeriodicThread requires the period in sec(double), so remember to consider a x1000 factor when migrate the code.
  • Several methods in public interfaces have a slightly different signature (see #1738 for details).
  • It is now possible to write a const Portable on a Port.
  • const Bytes and const ManagedBytes can no longer return non-const pointers to the underlying data.

YARP_dev

  • The serial device is no longer a plugin, but it is automatically built with YARP_dev.
  • The following devices are no longer built with YARP_dev and are now plugins:
    • ServerSoundGrabber
    • BatteryClient
    • BatteryWrapper
    • FrameTransformClient
    • FrameTransformServer
    • Localization2DClient
    • Map2DClient
    • Map2DServer
    • Navigation2DClient
    • Rangefinder2DClient
    • Rangefinder2DWrapper
  • The following headers were removed:
    • /yarp/dev/DeviceGroup.h
    • /yarp/dev/DevicePipe.h
    • /yarp/dev/IKinectDeviceDriver.h
    • /yarp/dev/IOpenNI2DeviceDriver.h
    • /yarp/dev/RemoteFrameGrabber.h
    • /yarp/dev/ServerFrameGrabber.h
    • /yarp/dev/ServerSerial.h
    • /yarp/dev/ServerSoundGrabber.h
    • /yarp/dev/TestMotor.h
    • /yarp/dev/RemoteFrameGrabberDC1394.h
  • A class of interfaces to wrap multiple analog sensors is now available in:
    • /yarp/dev/MultipleAnalogSensorsInterfaces.h
  • The devices multipleanalogsensorsserver, multipleanalogsensorsclient and multipleanalogsensorsremapper are available for exposing and accessing the multiple analog sensors over a network, and for combining multiple devices in a single device (remapper).
  • Major changes to IPidControlImpl.cpp to allow conversion of PID gains from metric to machine units.
  • Major changes to TorqueControlImpl to allow conversion of bemf, ktau parameters from metric to machine units.
  • Major changes to ControlBoardHelper classes, implementation is now contained in a separate .cpp file. Removed inline functions.
  • Added file PidEnums.h
  • Added missing method setNominalCurrentRaw() to IAmplifierControl interface.
  • Removed all control board interfaces methods e.g. setTorquePid(), setPositionMode() etc, marked as deprecated since 2.3.70
  • In ControlBoardWrapper functions for all joints invoke the equivalent function for all joints of motion control device. In the previous versions, that function call the equivalent function single-joint in a for-cicle, so the function for all joints in motion control devices have never been called. So please, check the implementation of function for all joints in your motion control device because now they will be invoked for the first time.

    • IVelocityControl2Raw in favour of IVelocityControlRaw.
    • IVelocityControl2 in favour of IVelocityControl.
    • ImplementVelocityControl2 in favour of ImplementVelocityControl.
  • IPositionDirectRaw::setPositionsRaw(const int, const int*, double*) became IPositionDirectRaw::setPositionsRaw(const int, const int*, const double*).
  • IPositionDirect::setPositions(const int, const int*, double*) became IPositionDirect::setPositions(const int, const int*, const double*)(#1351).
  • The file yarp/dev/ControlBoardInterfacesImpl.inl was renamed yarp/dev/ControlBoardInterfacesImpl-inl.h
  • Several methods in public interfaces have a slightly different signature (see #1738 for details).

  • Files are now in the yarp/rosmsg subfolder.
  • _indexALL.txt files are generated only for the requested types.

ControlBoardWrapper

  • Added error code in attaching subdevices.
  • Added realsense2 device.

IMotorEncoders interface bindings

  • IMotorEncoders interface methods can be used to directly monitor the motor shaft position and speed or even to control the motor positions individually when estimating coupled motors friction parameters.
  • Added bindings for the interface IMotorEncoders. The change extends the yarp::dev::PolyDriver and the yarp::dev::IMotorEncoders classes.

YARP_OS

  • Fixed race condition in yarp::os::Nodes.
