[PYTHON] I tried to let Pepper talk about event information and member information

At the following event of Basecamp Nagoya , I tried programming pepper for the first time.

Pepper Day "App Development for Pepper in Base Camp Nagoya"

What I challenged this time

This time, when I said "Tell me Pepper?", Pepper responded "Yes", and when I asked "What is today's event?", I asked "What is today's event?" We have created a program that will give you information about members checking in to the base camp when you ask "Who is coming?" For the latest event.

Environmental arrangement

First, download the Pepper development environment from the following site. https://community.aldebaran.com/en/resources/software/language/en-gb After downloading, various apps will be installed. From among them, launch the app with the C mark as shown in the figure below.

Pepper programming method

Basically, you can move the pepper just by combining the blocks that have already been programmed, but you have to program by yourself using Python that you can not do with the existing blocks. The wiring diagram of the program created this time is as follows. The blocks used are as follows.

Say block

Block to make pepper speak

Speech Reco block

A block for making pepper recognize voice. By separating words with; in this way, you can separate the words to be recognized. The recognized words span the next block.

Switch Case block

This is a block for conditional branching. This time, the conditions are divided according to the words recognized as follows.

Text Edit block

A block for passing a string to the next block. I want Pepper to pull the JSON data of the member information and talk, so I specify the JSON file I want to get as follows. At this time, the JSON file to be output is generated on the CMS side. In other words, the CMS manages everything that Pepper speaks. That will lower the threshold of Pepper's programming.

Python Script block

I didn't have a block to access the server and pull the JSON data, so I made it myself. Below is the source. However, dependent libraries such as json need to be downloaded separately.

import json, urllib2, sys, os, xml
 
class MyClass(GeneratedClass):
    def __init__(self):
        GeneratedClass.__init__(self)
 
    def onLoad(self):
        self.framemanager = ALProxy("ALFrameManager")
        pass
 
    def onUnload(self):
        self.framemanager = None
        pass
 
    def remove_tags(text):
        return ''.join(xml.etree.ElementTree.fromstring(text).itertext())
 
    def rest_request(self, url):
        self.folderName = os.path.join(self.framemanager.getBehaviorPath(self.behaviorId), "./lib")
        if self.folderName not in sys.path:
            sys.path.append(self.folderName)
        import requests
        try:
            r = requests.get(url)
            if r.status_code == 200 :
                return r.json();
            else:
                return False
        except:
            return False
        pass;
 
    def onInput_onStart(self, p):
        result = self.rest_request(str(p));
        output_text = "";
        i = 0;
        length = len(result);
        while i < length:
            output_text += str(result[i]['name'].encode('utf-8'))
            output_text += "\\pau=1000\\"
            output_text += str(result[i]['profile'].encode('utf-8'))
            output_text += "\\pau=3000\\"
            i += 1
        self.onStopped(output_text) 
        pass
 
    def onInput_onStop(self):
        self.onUnload() 
        self.onStopped() 
 
    def import_service(self):
        pass

Program packaging

After the program is completed, you can package the created program and install it in pepper by selecting Robot Application from the lower right panel and clicking the icon on the upper left as shown below.

Impressions

No. was fun. Usually, it's all about the front of the Web, so sometimes it's fun to program robots.
