Automaton Drawing

For my automaton I want to make a machine that types. I was originally intending to make a machine that could type a specific message, but Golan challenged me to make it so that the machine could type any words made with the tow row of a qwerty keyboard.

This automaton would be designed to fit over any full Apple keyboard, letting it interface with all of the computers in our clusters, as well as giving it some application to the wider world. I am as of yet uncertain what I exactly want it to type, although I am considering randomly generating phrases and selecting ones I like to use later. My instinct towards the generative that may not be suited to the piece, however.
