Sorry to derail....
Robots are our future (GM). I'm indirectly working on a project where we will be building the engine (for the Chevy VOLT) with Robots fastening down all the major components. Its the first of its kind for us where we are taking our robot integration to things more related to assembly than strictly supplychain type activities.
No more paying someone $30/hr to screw in a bolt. But then again, Robots don't buy cars, so who wins?
At least some one still has to bolt down the robots.
