Abstract: The initial setting method for the unmanned forklift includes a step of acquiring a measurement value of floor surface inclination of a stop position where the unmanned forklift stops when the unmanned forklift unloads a palette on a rack, a step of setting the stop position where a predetermined inclination pattern is detected, as a precise adjustment position, from the acquired measurement value, a step of causing the unmanned forklift to unload the palette in accordance with an operation program, and measuring a deviation amount of the palette unloaded by the unmanned forklift, at the precise adjustment position, and a step of correcting a command value of the unmanned forklift at the stop position, based on the measured deviation amount.

Abstract: An initial setting method of an unmanned forklift is an initial setting method when the unmanned forklift is introduced in a facility including a rack structure, which includes placing a palette for adjustment on a palette placing part of the rack structure using the unmanned forklift on the basis of a preset operation program, acquiring relative position information between the palette for adjustment and the rack structure using a position information acquisition part included in the palette for adjustment, and calculating the shift amount of the palette for adjustment placed on the rack structure with respect to the palette placing part on the basis of the relative position information.
