A defined vehicle path emulator system is described, which system can be used for measuring the F-min values and profiles for a path on a concrete floor traversed by a vehicle with a specific wheelbase. The defined vehicle path emulator is an autonomous robot that guides itself down the selected path.The F-min values are used to calculate the deviations away from zero planar infinity while traversing the path for a tall mast carried by an emulated vehicle. This invention's systems are distinct from the (FF/FL) floor flatness and floor levelness measuring systems in the literature as prior art.The floor can be marked for deviations from flatness by means of a laser etching system activated by the emulator's software system. The emulator can also signal an operator when it detects itself veering off of the defined path.
