Not only is spring in the air, so is Linux. But this wasn’t always the case. Early drones relied on either proprietary OSes or simple Arduino-based controllers such as the ArduPilot. While both of these approaches to drone control have been successful, they implicitly limit innovation — the former because they are closed systems, and the latter because of limited computing power. The recent introduction of Linux-based drones will stimulate the UAV (Unpiloted Aerial Vehicle) market by creating more flexible, open platforms. Here’s how Linux takes off … literally.
