How to setup the Raspberry PI

This are the instructions how to setup the raspberry PI for our usage.

Please note: These instructions may differ for other PI versions than Version 3 Model B.

Install Raspbian on th PI

We suggest to install Raspbian via the NOOBS installer. This is well described here:

https://www.raspberrypi.org/downloads/noobs/

After that you should have a running Raspbian installation on your PI.

Configure the PI

Please do the following to configure your PI:

• Run sudo raspi-config and change the password (default for "pi" is "raspberry")
• Connect the PI to your wireless network
• Run sudo raspi-config and enable SSH ("Advanced Options" -> "SSH")
• Optional: run sudo apt-get install vim
• Reboot your PI
• Clone our repository:
  cd /home/pi/
git clone https://github.com/codecentric/computer-vision-drone.git

Network config

Setup the network

• sudo nano /etc/network/interfaces
• add static address for wlan0:

  auto wlan0
  allow-hotplug wlan0
  iface wlan0 inet static
  address 10.10.58.104
  netmask 255.255.255.0
  gateway 10.10.58.1
  wpa-passphrase ******
  wpa-ssid SSID
  
  

• sudo nano /etc/wpa_supplicant/wpa_supplicant_bebop.conf
• paste the following code:

  ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
  update_config=1
  country=GB
  
  network={
           ssid="Bebop2-065599"
           key_mgmt=NONE
   }
  

• ctrl + x then y to save
• make sure that the following code is at the end of /etc/network/interfaces

  iface wlan1 inet manual
  wpa-conf /etc/wpa_supplicant/wpa_supplicant_bebop.conf
  

Install required frameworks

Install node.js

There are different ways to install node.js on the PI. Maybe you want to do it like this:

curl -sL https://deb.nodesource.com/setup_7.x | sudo -E bash -
sudo apt-get install nodejs

For Voice commands install: sudo apt-get install sox sudo apt-get install libatlas-base-dev If having problems with the microphone maybe this command can help: export AUDIODEV=hw:1,0

Install node.js modules

First, switch in the root directory of the project. Then do the following:

Install the HC-SR04 sensor module: npm install mmm-usonic --save

Install the wiring-pi module: npm install wiring-pi --save

Install the node-bebop module: npm install node-bebop --save or npm install git://github.com/hybridgroup/node-bebop#feature/firmware-4.0 --save

Install the net-ping module: npm install net-ping --save

Install the snowboy module: npm install --save snowboy npm install --save node-record-lpcm16
