Checking the NAOqi Python development environment

Introduction

• Installation of NAOqi C ++ development environment (OS X environment)
• Checking the operation of NAOqi C ++ development environment

It is a continuation. For the time being, I haven't confirmed the connection to the actual Pepper machine yet, so I tried it. Until now, I tried it with C ++ because of my interest, but this time I tried it with handy Python.

Run on Pepper real machine

Execution 4 (failure)

Connect to Pepper with API from your PC and run it.

hello.py

#!/usr/bin/python

from naoqi import ALProxy

tts = ALProxy("ALTextToSpeech", "192.168.3.58", 9559)
tts.say("Hello")

$ ./hello.py
[INFO ] Starting ALNetwork
[INFO ] NAOqi is listening on 127.0.0.1:54010
Traceback (most recent call last):
  File "./hello.py", line 5, in <module>
    tts = ALProxy("ALTextToSpeech", "192.168.3.58", 9559)
  File "/path/to/pynaoqi-python-2.7-naoqi-1.14-mac64/naoqi.py", line 282, in __init__
    inaoqi.proxy.__init__(self, args[0], args[1], args[2])
  File "/path/to/pynaoqi-python-2.7-naoqi-1.14-mac64/inaoqi.py", line 276, in __init__
    this = _inaoqi.new_proxy(*args)
RuntimeError:   ALNetwork::getModuleByName
        failed to get module ALTextToSpeech http://192.168.3.58:9559

It was an error.

It seems that such a thing appeared in the log on the Pepper side, so I connected, but it is probably "failed to get module ALTextToSpeech".

Execution 5 (success)

Connect to Pepper via SSH from your PC and run the API within Pepper.

>>> import naoqi
>>> from naoqi import ALProxy

First, try executing with localhost specified.

>>> tts = ALProxy("ALTextToSpeech", "localhost", 9559)
[I] 7615 qi.eventloop: Creating event loop while no qi::Application() is running
[I] 7615 qimessaging.session: Session listener created on tcp://0.0.0.0:0

[I] 7615 qimessaging.transportserver: TransportServer will listen on: tcp://192.168.3.58:42881
>>> tts.say("Hello")

Pepper said "Hello".

Next, try executing by specifying the IP address.

>>> tts = ALProxy("ALTextToSpeech", "192.168.3.58", 9559)
[I] 7994 qimessaging.session: Session listener created on tcp://0.0.0.0:0

>>> tts.say("Hello")

Pepper said "Hello".
