Alexa Go Go With RPi 3_part_1


I am figuring about the AI ROBOT platform with RPi 3 out.
And control the Alexa Go Go wirelessly.
i use arduino nano controlling the wheels with servo
and dc-motor controlling by the remoter(part_4).
maybe there are someone wondering about the IR remoter
that is not smart enough. so that i make with an
Alexa to drive it from upon the cloud.
means, to control the moving of the robot using voice command .

Make Alexa's Legs







Install RPi 3 to Set Up Alexa





Install RPi 3 to Desktop
1. RPI 3 * 1 (as Alexa's body)
2. HDTV * 1(FOR setup Alexa & as her mouth)
3. USB MIC * 1 (as Alexa's ear)
4. wireless keyboard & mouse * 1(FOR setup Alexa)

5. you need to build a security tunnel from the cloud to your RPi 3.
Visit https://ngrok.com/download and get the latest Linux ARM release as a zip
and unzip inside the home directory:
unzip /home/pi/ngrok-stable-linux-arm.zipNext,
run : sudo ./ngrok http 5000 (to run in memory)
Your screen should look like the image above. Note the 'Forwarding' URL that starts with https, it will be used later.
Note: Unfortunately the ngrok URL changes every time the service is started so it is not a permanent solution if you are trying to run this full time. I'd recommend a service like Yaler or Page Kite if you need a more permanent URL to use with your new Skill.
6. Python Script Open a new terminal session and create a new python file named gpio_control.py:
edit : nano gpio_control.py
example file:gpio_control.py
run : sudo python gpio_control.py (to run in memory)

Connect Your Alexa on the Platform


Testing With Your Keyboard



reference link :
Testing the Code With Alexa Upon the Cloud


run : sudo python gpio_control.py (to run in memory)
because of that this file use flask to control , so
if you don't have it you need to
install flask:
sudo apt-get update && sudo apt-get upgrade -y
sudo apt-get install python2.7-dev python-dev python-pip
sudo pip install Flask flask-ask
Test Run
