Or just let the government do it for free. Missile not included. Yet.
HEXO+ is an autonomous aerial drone by Squadrone System that films and follows users based on preset parameters. Users frame their shots via a smartphone app that calculates angles and height and distance. Once set, the drone continues to follow these parameters as the user begins moving so that it can continue to capture aerial footage of the same subject in the same way. Squadrone System is currently raising funds to make the jump to industrial production from working prototype via a Kickstarter crowdfunding campaign.
