one part i didn't fully get is if, after the training, the machine can calculate and implemente the same maneuvers while "offline" (not connected with any other device to assist with the navigation) and what would be the computing hardware requirements for smooth navigation without external help or update? (for example, guiding it with a joystick or GPS waypoint on rugged terrain and having it automatically adjust to each unforeseen obstacle in the way)
