Interesting read. I question though the need for a robot: why don't we use said sensing tech to empower Bob the Builder to "position brick within a seven mm" tolerance, and have the added advantage of well honed human heuristics judging a much wider variety of situations? From personal experience, the constraints that robotic manufacturing introduce in the design of an architectural object are huge: you end up designing specifically for the affordances of these tools, to the extent that you sometimes get nonsensical results.
