US2022058300 (A1) Vision and laser scanning and tracking systems are provided to allow the measurement of as-built slabs, bricks, the monitoring and adjustment of the process and the monitoring of safety zones. The first, or any course of bricks can have the bricks pre machined by the router module 47 so that the top of the course is level once laid. " Given variations in slab height, the desire to completely remove the need for a thick bed of mortar or thick adhesive between the slab and the first course of bricks requires a very level slab, level within a few mm of height tolerance. To achieve the slab height tolerance required for use of thin bed mortars would incur significant additional cost from concrete contractors. The provision of a router module in the invention allows bricks to be pre-machined based on measured slab elevation at the required brick location, which results in only a slight increase in build time, to machine in the router, each brick in the first course, so that the top of the first course is laid at the correct height and level, even on inaccurate slabs. Deviations of between 0 and 50 mm of flatness and level can be easily accommodated. Larger deviations could be accommodated if required. "
