Given how often McDs serves up burgers that are totally misaligned now, the robots don't have that high a bar to clear.
I was probably referring more to the taste/smell aspect. Visual presentation is also a part but that's my point. The robot will be programmed and engineered to always drop the bun in the same place.
And quality control is simply a matter of lasers and pattern recognition that already exists, it's not that hard to put together. Hell if someone can take an arduino, a toy squirt gun and video processing to recognize squirrels AND hit them with the stream in real time...that's a pretty significant creation done by a hobbyist.
