Navigation Computer

Navigation is done by a Jetson Nano and Pixhawk. These replace the High Level Arduino of previous versions.

A buck converter steps the 12V (orange) from DBW down to 5V (pink). The screw terminal on top provide 12V, CAN HI, CAN LO and ground. These may be connected to other CAN devices.

The Jetson Nano, Pixhawk, GPS and buck converter.

The task of the Navigation computer is to obtain waypoints defining the desired path and send CAN commands to DBW that will take the vehicle over the desired course. The Pixhawk is designed to be on the drone and communicate to a ground station. In this implementation, the ground station runs on the Jetson Nano and the connection is USB, instead of wireless. The Jetson Nano runs Ubuntu Linux. It has HDMI connectors for a screen and USB connectors for keyboard and mouse. These can be connected before the trike starts its journey, the course programmed, and the peripherals then removed.
