Build an autonomous, voice-controlled, face-recognition drone for $200 (oreilly.com)

Great write up! If you're not up for the read, it's worth watching the 45 second demo video at the bottom.

Looking forward to the follow up walk through on how to miniaturise this to the shape of a bee.

Lots of applications! Personalize greetings of visitors to a store or museum. Find a friend in a crowd. Search for a lost child in a park.

Instead of badges at a secure facility, the drone can patrol the place and call out anyone it can't recognize.

Brave new world.
