A New Message to Tyr

A simple, encrypted text-message:

Tyr, I know you are busy with a lot of things, but I need something from you. Could you construct a device similar to the one you recently made that can be used to remote-control a ship like the Turtle? Simple pre-programmed commands like "Power-up", "Land", "Come here", and "Come here really fast"? And simple enough that it could be installed by someone without much engineering expertise?

For a ship that small I could have it ready for you in a few days.
