Pittsburgh robot

We visited the robot down by the Allegheny River. He's got parts made of bridges and is Pittsburgh yellow. Beyond that, I'm not entirely sure what the inspiration is. We do have a robotics lab and Carnegie Mellon University. Perhaps that's it.

I love in the picture above that there is a bird perched on the robot's bridge head.

I have heard that the yellow used to paint the bridges over the Allegheny River in Pittsburgh is a specific yellow and that perhaps it's been trademarked. I can't find anything about it on wikipedia nor from a quick internet search. So, I'm just spreading unsubstantiated rumors here...
