Animations

These actions currently only work on Nao/Pepper robots. Use the computer-robot JAR to emulate the expected responses to these actions locally if needed.

set_breathing(bool)

Starts/Stops breathing animations on the robot, based on the truth value of the parameter (1 enables breathing, 0 disables it)

A BreathingEnabled or BreathingDisabled event will be sent when this is done.

Example: set_breathing(1).

do_gesture(Animation)

Performs the given animation. See http://doc.aldebaran.com/2-5/naoqi/motion/alanimationplayer-advanced.html  for the available animations per robot.

A GestureStarted and GestureDone event will be sent before the animation plays and after it finishes respectively.

Example: do_gesture('animations/Stand/Gestures/Hey_1').

go_to_posture(Posture,Speed=100)

Make the robot go the given posture at the given speed (0-100; default when it's left out is 100% speed). See http://doc.aldebaran.com/2-5/family/pepper_technical/postures_pep.html#pepper-postures  and http://doc.aldebaran.com/2-8/family/nao_technical/postures_naov6.html#naov6-postures  for the available postures on Peppers and Naos respectively.

A posture percept will be sent reflecting any change in posture.

Example: go_to_posture('Stand', 50).

play_motion(RecordedMotion)

See the start_motion_recording action for more information; the data that comes out of such a recording can be fed into this action.

start_listening(Timeout,Context='')

A PlayMotionStarted and PlayMotionDone event will be sent before the recording is performed and after it has finished respectively.

The method can also play the XML-file at the given path (e.g. from Choregraphe), with optionally an emotion that will be used to modify the given animation.

The emotion can be one of: [fear, mad, supersad, alarmed, tense, afraid, angry, annoyed, distressed, frustrated, miserable, sad, gloomy, depressed, bored, droopy, tired, sleepy, aroused, astonished, excited, delighted, happy, pleased, glad, serene, content, atease, satisfied, relaxed, calm].

A PlayMotionStarted and PlayMotionDone event will be sent before the recording is performed and after it has finished respectively.

Example: play_motion('Animation.xml').

rest

Make the robot go into rest mode. This is the inverse of the wake_up action.

An is_awake percept will be sent reflecting any change in the state of the robot.

set_ear_colour(Colour)

Set the colour of the robot's ear LEDs. The Colour can be either a predefined single colour (white, red, green, blue, yellow, magenta, or cyan), a predefined combination (rainbow or greenyellow), or an RGB-colour given in hexadecimal: 0x00RRGGBB. On the Pepper, the ear LEDs can only be various shades of blue.

Example: set_led_color(['LeftFaceLeds','RightFaceLeds'],['yellow','orange']).

set_non_idle

Disable the 'idle' mode of the robot. This means its head will move in the robot's autonomous mode, which is the default behaviour. 

A SetNonIdle event will be sent when the robot is back into autonomous head movement.

set_stiffness(JointList,Stiffness,Duration=1000)

Sets the stiffness of one or more of the robot's joints ([Head, RArm, LArm, RLeg, LLeg] on the Nao and [Head, RArm, LArm, Leg, Wheels] on the Pepper).

Audiovisual

These action work on any supported audio device (a robot, laptop, tablet, etc.)

clear_loaded_audio

A ClearLoadedAudioDone event will be sent once this has completed.

stop_recording

Prevent the Dialogflow service from sending the audio it processes to the client (which is not done by default; see enableRecording).

load_audio(Path)

Preload the given audio file (which can be either a local file or a remote url) on the audio device. This prevents the audio device from having to download the file when calling playAudio.

The result (once the audio file is preloaded) is a loadedAudioID percept, which gives you an identifier to use in the playLoadedAudio action.

Example: load_audio('12-00-00.wav').

play_audio(Path)

Directly play the given audio file (which can be either a local file or a remote url) on the audio device.

A PlayAudioStarted and PlayAudioDone event will be sent when the audio starts playing (i.e. after it has been loaded on the audio device) and when it has finished playing respectively.

say(Text)

Use text-to-speech to make the audio device play the given text. The exact results depends on the device that is used.

A TextStarted and TextDone event will be sent when the device starts playing the text and after it has completed this respectively.

Example: say('Hello, world!').

say_animated(Text)

The same as say(Text), but on a Nao/Pepper the robot will automatically add some animations whilst saying this text.

A TextStarted and TextDone event will be sent when the audio device starts playing the text and after it has completed this respectively.

Example: say_animated('Hello. Goodbye!').

set_language(LanguageKey)

Set the language to be used by the audio device's text-to-speech engine and Dialogflow's speech-to-text engine. By default, if a flowLang is given in the init parameters, this language will be set accordingly; otherwise it is 'nl-NL' by default.

A LanguageChanged event will be sent when the text-to-speech engine has switched language (Dialogflow will use the given language for the next detection).

Example: set_language('en-US').

Opens up the selected microphone and starts streaming the audio, e.g. to Dialogflow, either until the Timeout (in seconds, possibly with decimals) has been reached or a stopListening action is called. If the given Timeout is 0, the microphone will remain open until stopListening is called. The optional Context in this action is fed to Dialogflow (see RecordMotion: JSON string format (see below)

        {'robot': <'nao'/'pepper'>, 'compress_factor_angles': <int>, 'compress_factor_times: <int>
        'motion': {'joint1': { 'angles': [...], 'times': [...]}, 'joint2': {...}}}

Output via callback after stop_motion_recording (needs start_motion_recording) can be input for this function.

play_motion_file(file_path)

Example: set_speech_param('speed', 200) for making the robot speak two times faster.
