The machine in the video you linked to is neat but it actually serves to illustrate my point. Move the ingredient dispensers a few centimeters in any direction, change the cooking plate temperature and watch what happens. This machine is simply playing back a programmed set of motions. The fact that it looks complex and anthropomorphic does not make it intelligent. Any FIRST Robotics League team in the US could build a machine to do this for a lot less money.
When I had my own electronics manufacturing operations in house I always looked for opportunities to add robotics to improve the process. In almost every instance it was far more efficient to add a custom or semi-custom single-purpose tool than to even attempt to use a programmed manipulator of any kind. The combination of a person with a set of custom tools can be very efficient. Now, of course, I never did mass production. That's an entirely different game. Even then, you'll see programmed machines do tasks like dispense adhesives or gasket material. In nearly all cases an indexing fixture carefully aligns the workpiece and the robot/machine executes a canned motion cycle. These machines are not intelligent at all. They might appear to be, but they are not.
