Hardware needed
For installing and utilizing the line follower application for RegBot robots the following things are needed:
- A fully functional RegBot programmed with latest version of the robot software. Consult this section to ensure that.
- A clean Raspberry Pi (model 2 and above is preferred). In case the Pi is clean with an OS newly installed simply skip the install OS section in Software Installation.
- A Raspberry Pi camera modul.
- A mount for Raspberry Pi + camera module. Consult JCA for this.
- A few female/female jumper wires for connecting the Raspberry Pi with the RegBot.
- A WiFi dongle e.g. EDIMAX EW-7811Un (Raspberry Pi model 3 includes WiFi).
Also it would be good to have access to a "HDMI input"-screen in order to locally make the initial connection to WiFi and setup SSH for remote access.

Installing the OS
Use this link to download and install the newest Raspian OS on a SD card. Detailed instructions on how to write an image to a SD card is found within the link as well.
When the OS has been successfully installed insert the SD into the Raspberry Pi - connect a screen via the Pi's HDMI output and a keyboard + mouse set.
Setting up WiFi
Plug in the WiFi dongle and open up a terminal window.
In terminal open the wpa-supplicant configuration file:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf
Go to the bottom of the file and the information about the WiFi:
network={
ssid="Your_SSID"
psk="Your_wifi_password"
}
Save the file by pressing Ctrl+X then Y, then finally press Enter.
Restart the Pi by typing sudo reboot and it should automatically connect to WiFi when finished restarting.
