Aldebaran documentation What's new in NAOqi 2.4.3?

NAOqi API & SDks 2.1

Addendum - 23 September 2014

ALFaceDetection: OMRON solution instead of OKI

ALFaceDetection is now based on a face detection/recognition solution provided by OMRON.

As the two technologies, OMRON and OKI, do not provide the same set of data, and for backward-compatibility, the structure of the data returned has not been modified, but the pieces of data formerly provided by OKI have been replaced by null values.

For further details, see: FaceDetected Event.

Few steps toward human behavior

New module: ALDialog

The ALDialog module allows you to endow your robot with conversational skills by using a list of “rules” written and categorized in an appropriate way.

For further details, see: ALDialog.

New module: ALAnimatedSpeech

The ALAnimatedSpeech module allows you to make the robot talk in an expressive way.

For further details, see: ALAnimatedSpeech.

New tracking system

New module: ALTracker

ALFaceTracker and ALRedBallTracker are now deprecated. They are replaced by a new and more generic module: ALTracker.

ALTracker module allows the robot to track different targets (red ball, face, landmark, etc) using different means (head only, whole body, move, etc).

The main goal of this module is to establish a bridge between target detection and motion in order to make the robot keep in view the target in the middle of the camera.

For further details, see: ALTracker.

New extractors - Basics

New module: ALVisualSpaceHistory

ALVisualSpaceHistory keeps track of the head movements of the robot to build a timestamped map of the head positions. This can be useful when exploring the environment to make the robot look in every directions.

For further details, see: ALVisualSpaceHistory.

New module: ALSegmentation3D

3d This module requires a robot with a 3D sensor.

ALSegmentation3D extracts the objects present in the field of view of the robot by doing a segmentation of the depth image (returned by the 3D sensor) in blobs of similar depth.

It also allows you to track, with the head of the robot, a blob at a specified distance or simply track the nearest blob with respect to the camera.

For further details, see: ALSegmentation3D.

New extractors - For People Perception

New module: ALBasicAwareness

ALBasicAwareness is a simple way to make the robot establish and keep eye contact with people.

For further details, see: ALBasicAwareness.

New module: ALPeoplePerception

ALPeoplePerception is an extractor which keeps track of the people around the robot and provides basic information about them. It gathers visual information from RGB cameras and a 3D sensor if available.

For further details, see: ALPeoplePerception.

New module: ALEngagementZones

ALEngagementZones allows you to detect if someone is approaching the robot, or moving away, using the concept of engagement zones.

For further details, see: ALEngagementZones.

New module: ALFaceCharacteristics

ALFaceCharacteristics updates every person with some additional information such as an estimation of age and gender. It also tries and detects whether the person is smiling.

For further details, see: ALFaceCharacteristics.

New module: ALGazeAnalysis

ALSittingPeopleDetection updates every person with the information of whether he or she is sitting (on a chair for example) or standing.

For further details, see: ALSittingPeopleDetection.

New module: ALWavingDetection

3d This module requires a robot with a 3D sensor.

ALWavingDetection allows you to detect if a person is moving in order to catch the robot’s attention (for example waving at the robot).

For further details, see: ALWavingDetection.

SDKs, Bindings

Control NAO from your web browser - QiMessaging JavaScript

QiMessaging provides JavaScript bindings to use QiMessaging services (modules) in a web browser. It allows you to build HTML5 application for your robot.

For further details, see: QiMessaging JavaScript 1.0.

Python SDK: Python2.7 only

Python 2.6 is not anymore supported.

Moreover, Choregraphe uses now Python 2.7 to interpret its scripts.

C++ SDK: end of VS2008 support

Support for Visual Studio 2008 is gone. This will let us focus on supporting new compilers (Visual Studio 2012), and new architectures (windows 64 bits) in the future.

C++ SDK: end of Ubuntu 10.04 LTS (Lucid) support

Ubuntu 10.04 LTS (Lucid) is not anymore supported.

This release only supports Ubuntu 12.04 LTS (Precise) and later.

For further details, see: compatible-platforms.

C++ SDK: change in qiBuild numbering

qiBuild has now its own release cycle. This means:

  • qiBuild now has its own version number (2.5 at the moment of writing), distinct from the version number of the SDK.
  • There are now new qiBuild releases every months or so: follow the project on github (https://github.com/aldebaran/qibuild) to be informed of new releases.

This should not change anything because the latest qiBuild release will always be retro-compatible with the latest Aldebaran C++ SDK.

C++ SDK: breaking changes

During the re-factoring of the framework libraries, some minor incompatible changes were introduced.

  • BIND_METHOD macro call must now be followed by a colon:

    // old:
BIND_METHOD("myMethod", "MyModule", "Documentation for myMethod")

// new
BIND_METHOD("myMethod", "MyModule", "Documentation for myMethod");

  • ALCOMMON no longer depends on ALTHREAD, so if you are using it, you must patch the CMake code

    # Old:
qi_use_lib(my_module ALCOMMON)

# New:
qi_use_lib(my_module ALTHREAD ALCOMMON)

Simulator SDK: multiple robot Models

Support for multiple robot models was added.

Simulator SDK: NAOqi automatic Launch

NAOqi is now automatically launched at startup.
