Every year hundreds of millions of dollars are lost due to human errors in the layout of construction information. When an architect has finished their drawings and they need translated to the freshly poured foundation of a building, it is usually handled by construction workers using tape measures and chalk lines.
The workers identify where key structural elements will be placed based; locations of studs, walls, stairwells, doorways, etc.
Inches matter. Seemingly small errors can turn into gigantic financial and time losses as construction comes to a screeching halt, because a key structural beam was incorrectly placed by 18 inches.
Solution? => Using off the shelf components to create a simple wheeled robot capable of marking concrete with spray paint. CAD design files for the layout can be wirelessly uploaded to the robot. Relative location determined by rotating laser range finder and datum poles placed on site.
