Today a crew snaps the building outline onto the floor by hand: tape, chalk lines, hours of measuring, and drift on every corner. MERGEN does it itself, accurately, in one pass.
Load the floor plan — partitions, columns, window openings, plumbing, kitchen casework, room labels. Every element becomes a colour-coded layer the robot will lay down.
DXF / plan → layersA differential drive on two NEMA-23 closed-loop steppers carries it across the pour, routing cleanly around the columns and roughed-in plumbing already standing on the deck.
Closed-loop drive · obstacle-awareA Unitree L2 LiDAR feeds FAST-LIO SLAM to pin the robot to the slab within ±2 cm — drift-free. Closed-loop encoders catch every step. Accuracy is the whole point: the Blind Tank's job is to not drift.
LiDAR SLAM · ±2 cmA custom marker toolhead drops a felt pen with a laser reference and draws each line where it belongs — then TIJ-prints the room labels in straight passes. Walls, windows, fixtures and casework go down in their own colours.
Marker toolhead · TIJ textWhat's left is a complete, accurate, colour-coded plan on the concrete — every wall, door, and fixture marked exactly where the trades need it. Hours of layout, done unattended.
Full plan · trade-readyA cinematic teardown of every part, an interactive 3D model, and the full bill of materials — all in one place.
