Abstract:
1. A method for mounting a pattern in an automated guided vehicle, the pattern being drawn by dot-sequential data indicating a temporal variation in acceleration, the pattern corresponding to an instruction value provided to an actuator installed in the automated guided, comprising: deriving a curve function expressed as a finite series corresponding to an approximate expression for the dot-sequential data, said curve function uses time as an independent variable and the acceleration as a dependent variable; dividing the dot-sequential data into a plurality of parts to derive the finite series for each of the plurality of parts, said plurality of parts correspond to the pattern drawn by the dot-sequential data indicating the temporal variation in the acceleration, wherein the plurality of parts represent an accelerated running portion, a uniform-speed running portion and a decelerated running portion; storing, in a memory mounted in the automated guided vehicle, coefficients of terms constituting the finite series for the accelerated running portion and the decelerated running portion, and storing a constant in the memory indicating the temporal variation in acceleration, instead of the coefficients of the terms constituting the finite series for the uniform-speed running portion, wherein controlling the automated guided vehicle based on the data for the finite series for the accelerated running portion and the decelerated running portion and the constant for the uniform-speed running portion stored in the memory.
