Question about generating an app for localization of Pepper robot

[Frederik201314]

Hi there,

These days I have tried to generate an application using the pythonapp template to do the localization of Pepper. My basic idea is to combine the LandmarkDetector module in the generated app „Lokalisierung“(Localization of German).

You can read the whole code here:

“ MainLandmarkDetection.py“:

"""
A sample showing how to make a Python script as an app.
"""

__version__ = "0.0.8"

__copyright__ = "Copyright 2015, Aldebaran Robotics"
__author__ = 'YOURNAME'
__email__ = 'YOUREMAIL@aldebaran.com'

import stk.runner
import stk.events
import stk.services
import stk.logging

class Activity(object):
    "A sample standalone app, that demonstrates simple Python usage"
    APP_ID = "com.aldebaran.lokalisierung"
    def __init__(self, qiapp):
        self.qiapp = qiapp
        self.events = stk.events.EventHelper(qiapp.session)
        self.s = stk.services.ServiceCache(qiapp.session)
        self.logger = stk.logging.get_logger(qiapp.session, self.APP_ID)

    def on_touched(self, *args):
        "Callback for tablet touched."
        if args:
            self.events.disconnect("ALTabletService.onTouchDown")
            self.logger.info("Tablet touched: " + str(args))
            self.s.ALTextToSpeech.say("Yay!")
            self.stop()

    def on_start(self):
        "Ask to be touched, waits, and exits."
        # Two ways of waiting for events
        # 1) block until it's called

        self.s.ALTextToSpeech.say("Touch my forehead.")
        self.logger.warning("Listening for touch...")
        while not self.events.wait_for("FrontTactilTouched"):
            pass

        # 2) explicitly connect a callback
        if self.s.ALTabletService:
            self.events.connect("ALTabletService.onTouchDown", self.on_touched)
            self.s.ALTextToSpeech.say("okay, now touch my tablet.")
            # (this allows to simltaneously speak and watch an event)
        else:
            self.s.ALTextToSpeech.say("touch my tablet ... oh. " + \
                "I don't haave one.")
            self.stop()

    def stop(self):
        "Standard way of stopping the application."
        self.qiapp.stop()

    def on_stop(self):
        "Cleanup"
        self.logger.info("Application finished.")
        self.events.clear()

if __name__ == "__main__":
    stk.runner.run_activity(Activity)

This is how it worked in cmd.exe:

And I have a question to the parameter by ”landmark_detector = Activity(Parameter)” in line 157 at almost the end of the program because of the Error in the image, which I should pass, if you have a little time for that. I think it schould be a value that should be given to the "qiapp", but what value?

Best regards,
Frederik
