Hi All ,
Can the Autopilot function without an RC transmitter ?
Also I currently have a Pixhawk system running with a tablet (andropilot app) . Can Erle-brain function in the same way and display telemetry and receive inputs via the tablet ?
Sure. You only need the RC transmitter if you want to teleoperate the drone. For example you can fly using a Joystick. This link explains how to do it or maybe using ROS.
Erle-Brain runs the same software that you run in your Pixhawk (ArduCopter). You can receive over telemetry or WiFi the data from the autopilot in your tablet.
thank you @ahcorde
