I made this tab after I heard the acoustic version of the song. I basically play it with 
chords.

Same chords: D, G, A, B

And the impression of my self machine
The word was spoken and it was foreseen
Now we're too well too bothered in between
A pixel lost on the computer screen

A, B, G, D

Lonely robot in a wasteland
Rusting in a lonely harbor
Lonely robot in a wasteland
Rusting in the harbor's water

B, A, D
I'm not a human if you say I'm not
I'm not a human if my engines lock
And this motor that you call my heart
Is another machine that wont stop

Lonely robot in a wasteland
Rusting in a lonely harbor
Lonely robot in a wasteland
Rusting in the harbor's water

I'm not a human if you say I'm not
I'm not a human if my engines lock
And this motor that you call my heart
Is another machine that won't stop

I'm not a human if you say I'm not
I'm not a human if my engines lock
And this motor that you call my heart
Is another machine that won't stop
