make a raspberry pi 3 cluster that has all the USB ports off it the Ethernet port, HDMI, the audio/video port then hard wire the Ethernet (leave the head pi Ethernet port on it) then to finish off the cluster put a screen on the main pi so that you can add code to the cluster an A.I and use a raspberry pi zero over wireless ssh and let the A.I fly the drone. then you could throw a cam, speaker and mic on the drone so you can also do voice commands and even put Facial Recognition on.As for voice commands like you could program it so if it hears the words call 911 it will call 911 or call mom it call mom. I wish you would build this that would be cool and i don't have a phone right now .
