CAT-BOT

I used to dream of my kitty talking to me and now I am going to make my toy kitty react to my actions and even CHAT WITH ME!

Let's make a draft about the project.

Firstly I need a raspberry pi, which has a Linux OS, can compile Python and even has an access to the Internet.

Secondary I would like to use Arduino to get some data as well as realize some basic physical reactions.

Thirdly a webcam is required to capture user actions.

Finally is to make the connection to an AI chatbot.

Material List:

Raspberry Pi 3 Model B

5MP Night Vision Camera for Raspberry Pi

DFRduino UNO R3 [ similar as Arduino UNO R3 ]

USB Cable A-B for Arduino Uno/Mega

Waterproof DS18B20 Sensor Kit

9g micro servo (1.6kg)

and a monitor is required for raspberry pi

Just have everything in their right position.

just go through this Tutorial

Hint: just install the RASBAIN

here is a test code from pythonprogramming.net

import io

import picamera

import cv2

import numpy

#Create a memory stream so photos doesn't need to be saved in a file

stream = io.BytesIO()

#Get the picture (low resolution, so it should be quite fast)

#Here you can also specify other parameters (e.g.:rotate the image) with picamera.PiCamera() as camera: camera.resolution = (320, 240) camera.capture(stream, format='jpeg')

#Convert the picture into a numpy array

buff = numpy.fromstring(stream.getvalue(), dtype=numpy.uint8)

#Now creates an OpenCV image

image = cv2.imdecode(buff, 1)

#Load a cascade file for detecting faces

face_cascade = cv2.CascadeClassifier('/usr/share/opencv/haarcascades/haarcascade_frontalface_alt.xml')

#Convert to grayscale

gray = cv2.cvtColor(image,cv2.COLOR_BGR2GRAY)

#Look for faces in the image using the loaded cascade file

faces = face_cascade.detectMultiScale(gray, 1.1, 5)

print "Found "+str(len(faces))+" face(s)"

#Draw a rectangle around every found face for (x,y,w,h) in faces:

cv2.rectangle(image,(x,y),(x+w,y+h),(255,255,0),2)

#Save the result image

cv2.imwrite('result.jpg',image)

connect the Raspberry Pi and the Arduino Uno with the cable.

After installing pySerial, reading data from Arduino is straightforward:

>>> import serial

>>> ser = serial.Serial('/dev/tty.usbserial', 9600)

>>> while True:

... print ser.readline()

'1 Hello world!\r\n'

'2 Hello world!\r\n'

'3 Hello world!\r\n'

Writing data to Arduino is easy too (the following applies to Python 2.x):

>>> import serial # if you have not already done so

>>> ser = serial.Serial('/dev/tty.usbserial', 9600)

>>> ser.write('5')

Hint: http://playground.arduino.cc/Interfacing/Python

I have a temperature sensor which would give feedback when (you petting the kitty) the temperature reaches some pre-set height.

I decided to have the bot make some feedback when I petting it.

eg. 'Meow! Keep going that way.'

'Purrrrrr. How is your day today my slave?'

'STILL NO GIRLFRIEND!?'

So I wanna set each of those sentences a number and make a random function to print any of those sentences on my screen(I would use ssh to connect to the raspberry pi) after I petting it for ten minutes or even longer.
