Lily, a camera drone

Throw this drone in the air and it flies itself following you!

Lily started in September 2013 in the basement of a UC Berkeley robotics lab, where Henry Bradlow and Antoine built the first prototype using a Raspberry Pi and an Arduino.

It follows a small circular tracker, which you can have in your pocket or on your wrist. With one tap of the tracker, Lily can execute some nifty camera moves, all while staying focused on you. The camera inside, Bradlow says, is roughly equivalent to the GoPro Hero 3: It can shoot 1080p video, or 720p up to 120 frames per second—there’s some tech inside that will detect when you hit a jump while snowboarding and automatically kick the camera into slow-mo. It’ll also shoot 12-megapixel stills and it can make a cool 360-degree panorama. It can fly 25 miles per hour, is totally waterproof, lasts up to 20 minutes on a charge, and has range up to 100 feet. check out for official website from lily https://www.lily.camera/
