UNMANNED CARRIER

摘要

PROBLEM TO BE SOLVED: To provide an unmanned carrier which can prevent deviation from a track and travel at a high speed while minimizing the decrease in conveyance efficiency.SOLUTION: An unmanned carrier 10 which automatically travels along a prescribed track line comprises: a track line detection sensor 16 for detecting the track line; and a control part 15 for performing travel control so that it travels along the track line on the basis of a detection result by the track line detection sensor. The control part counts the number of cases in which deviation exceeding a prescribed amount in the left or right direction occurs and performs deceleration control to decelerate to a prescribed speed if the number of successive deviations exceeding the prescribed amount reaches a prescribed number.SELECTED DRAWING: Figure 1
