Time warp multiplies simulated seconds per real second. At 1x one brick takes about 9 s, like the real thing.
Lays the first scaffold lift (20 courses) headless with 1, 2 and 3 robots on the current wall and bond. Ideal speed-up equals the robot count; the shortfall is travel, waiting for supporting bricks and uneven station splits.
The science
Brick and joints. Waal-format brick 210 x 100 x 50 mm plus 10 mm joints gives a pitch of 220 x 60 mm, so one square metre of stretcher face needs 1/(0.22 x 0.06) = 75.8 bricks. Mortar is 1 - (0.21 x 0.05)/(0.22 x 0.06) = 20.5 % of the veneer volume; the sim adds the waste factor you set (typical 10 to 30 %).
Bond and lap. Running, Flemish, English and one-third bond shift head joints between courses. A common rule of thumb asks for a lap of at least a quarter brick (52.5 mm). Stack bond lines the joints up (lap 0), so it is shown as a failed check: it is decorative, not load-sharing.
Curved facade. Each brick is straight; on a circle of radius R its outer corners lie (l/2)^2 / 2R outside the arc (0.39 mm at R = 14 m, l = 210 mm). Head joints become tiny wedges, which the mortar absorbs.
Arm kinematics. Two links (L1 = 1.30 m, L2 = 1.25 m) in a vertical plane under a turret: cos(th2) = (h^2 + dy^2 - L1^2 - L2^2) / (2 L1 L2), elbow up, gripper kept vertical. Moves are joint-space minimum-jerk curves s(t) = 10t^3 - 15t^4 + 6t^5 whose duration is set by the slowest joint (peak speed 1.875 x distance / time).
Torque and energy. Gravity torque at the shoulder is the derivative of potential energy; electrical power is a 0.4 kW base load plus mechanical power / 0.7 (assumed efficiency) plus 1.5 kW while driving. Link masses (48 / 34 / 14 kg gripper) and the 2.1 kg brick are assumptions.
Supply. Pallets carry 405 bricks, the tub 100 L; the crane and the mortar pump take 25 s and 20 s (illustrative). The scaffold deck climbs in 1.2 m lifts, the reach window of the arm.
Simplifications. No wall stability, wind load, curing, mortar open time or collision checking. Robot speeds, masses and times are plausible round numbers, not data from any product. Real systems (e.g. commercial brick-laying robots) differ.
