Erle-Brain 3 is the third generation of Linux-based artificial robotics brain for making robots and drones with official support for the Robot Operating System (ROS). It supports lot of vehicles and can be used for new ones. It is an all-in-one Linux brain.
Drones deployed in real applications have several computational units. Among them, there is the Flight Control Unit (FCU) —a computer that provides basic flight controls, and a companion computer— a computational device in charge of higher level behaviors such as image processing or image broadcasting.
