Important insights from this article: - The hard part is the mortar - Any useful number of brick lays will require after placement adjustment to maintain level/true alignment - Those adjustments are where a good deal of 'skill' comes in - Finishing / jointing is even harder So it looks like this is an RL problem and the focus of the research needs to be geared toward the above. Basically you need a system to understand mortar and how to place various shapes of objects in it so that over time you achieve the goal of a specific wall shape. This problem suggests an arm-farm like setup. Normally I always urge sim-first, but I'm not aware of any useful simulator that can do non-Newtonian fluids and robotic systems well. (either sure, but both? Let me know if you know of one.)
