Abstract
An automated lane surface measuring device comprising a controller for operating a drive mechanism for propelling the measuring apparatus and one or more sensors operated by the controller to measure topographical parameters of the bowling lane surface. In one embodiment the apparatus measures bowling lane surface elevation by measuring bowling lane height with respect to the measuring apparatus in selectable increments along the surface of the bowling lane. The measuring apparatus may also measure crosswise tilt along the width of a bowling lane in selectable increments. The measuring apparatus may also measure lengthwise tilt of the length of the lane surface in selectable increments.
