自動搬送車のための音響誘導システムの最適化

抄録

An automated guided vehicle (AGV) cannot reach its desired position unless its position is detected and its movement is controlled. This study mounts two sound sources on a moving object modeled on the AGV, one on the left side and the other on the right side of the object. The positions of the sound sources are detected as they emit sounds at different frequencies. In addition, the numbers of revolutions of two wheels that are driven independently from the sound sources are controlled to guide the moving object to the desired position. This paper presents a basic test in which the hardware and software parameters of the proposed guidance system are optimized by the parameter design in quality engineering. Model-based testing as it is, it demonstrates that parameter optimization of the guidance system leads to swift and accurate guiding of the moving object to the desired position. This test result confirms the feasibility of the sound guidance system for AGVs.
