raspi car

Raspi car is a little Raspberry pi powered robot. You can control it trough a web interface.

The backend is powered by flask, gevent and flask-socketio.

Parts needed:

raspberry pi
Pimoroni explorer hat pro
motors
battery pack
chassis for robot

You should install a few packages:

sudo apt install python-dev nginx git python-pip

Now you need to clone this repository and enter it:

git clone https://github.com/trirpi/raspi-car.git
cd raspi-car

Then you need to install the requirements. When you are in the home directory:

sudo pip install -r requirements.txt

Then you need to setup nginx as a reverse proxy. So you need to edit /etc/nginx/sites-enabled/default to look like the following. Change with your ip. You can retrieve your ip by typing hostname -I.

server {
    listen 80;
    root /home/pi;

    server_name <ip of your pi>;

    access_log  /var/log/nginx/access.log;
    error_log  /var/log/nginx/error.log;

    location / {
        proxy_pass         http://127.0.0.1:5000/;
        proxy_redirect     off;
        proxy_set_header   Host                 $host;
        proxy_set_header   X-Real-IP            $remote_addr;
        proxy_set_header   X-Forwarded-For      $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto    $scheme;
    }   
}

Then you need to start and restart nginx:

sudo service nginx start
sudo service nginx restart

As a final step you should edit the sockets.js file located in raspi-car/rcar/static/js/. To have the socket connect to your raspberry pi's ip.

Then you just run the program:

python start_rcar.py

When everything is working correctly you can navigate to the raspberry pi's ip in the browser and there is your web interface where you can drive forward/backword/left/right.

Enjoy!

Give my repo a star :) it helps me a lot.
