In the context of automation, the "robotic revolution" has already happened between the 4 industrial revolutions - basically, robots exist en masse already, we just don't call them robots. The majority of manufacturing and processing is already hyper optimized to only needing a few overseers to make sure the machines are running smoothly.
When talking about the automation revolution, I think it's important to make the distinction between robotic tooling and autonomous robotic systems, even though they evolve from each other. The difference is when humans interface and at what abstraction humans can operate it on. Generally, tooling is constrained to an individual's output. Robotic augmentation is in it's own category as well (human activities being enhanced by machinery).
Tooling is extremely useful, still has a lot of future potential and I don't mean to undermine work on new tooling. Just - usually when we look at robots, especially with the buzz around deep learning, we set the bar for problem solving at the level of autonomous construction because we assume, sometimes incorrectly, that optimizing our current tooling yields little efficiency benefits relative to the former.
