He's a creation of genius comic artist Nedroid.

this is him:

Where is he going? Nedroid puts him in a lot of drawings. He's been to so many places, seen so may things. He's on some manner of journey, but i don't know from where or to where. I think if i did it might kill the magic. His wanderlust is very endearing.

I dunno why i felt like writing a short dissertation on a comic robot, but there it is. You read it, and now you can't unread it.
