RoboPi

RoboPi code for use with Raspberry Pi to build a controllable robot.

This is the code I've used to get a two geared motor robot up and running on my raspberry pi. It allows control over http and streams from a webcam attached to the front.

Dependencies needed
python 2.7.3 or greater (tested only on 2.7.3)
python RPi.GPIO
Adafruit occidentalis operating system.
nginx

Installation steps

1. Install nginx
   sudo apt-get install nginx

2. Clone this github code to the Pi.

3. Copy the contents of the www folder to /usr/share/nginx/www/

4. Copy server.py to /home/pi/

5. Copy mjpg_streamer and robopi-server to /etc/init.d/ and make executable:
   sudo chmod +x /etc/init.d/mjpg_streamer
   sudo chmod +x /etc/init.d/robopi-server

6. Set mjpg_streamer and robopi-server to start on boot:
   sudo update-rc.d mjpg_streamer defaults
   sudo update-rc.d robopi-server defaults

7. Install mjpg_streamer - this is outside the scope of this README, head over to http://sourceforge.net/projects/mjpg-streamer/

8. Edit /etc/nginx/sites-enabled/default and under the server directive add these two locations at the end:
   location /webcam/ {
   proxy_pass http://127.0.0.1:8080/;
   }
   location /json/ {
   proxy_pass http://127.0.0.1:8090/;
   }

9. Edit /home/pi/server.py and set the pin configuration that you have chosen to use to connect your motors.

10. Reboot your Pi.

11. Login to http://ip.ip.ip.ip/ and start to control your RoboPi :)
