Title: Tatsuya Shiga: Innovator in Work Machine Control Systems

Introduction

Tatsuya Shiga is a prominent inventor based in Chigasaki, Japan. He has made significant contributions to the field of work machine control systems, holding a total of five patents. His innovative work focuses on enhancing the efficiency and accuracy of work machines through advanced control methods.

Latest Patents

Among his latest patents are a work machine control system, a work machine, and a work machine control method. The work machine control system includes a position sensor that detects the position of a work machine traveling on a designated path. It features first and second non-contact sensors that detect the position of objects around the work machine. A map data creation unit generates map data based on the detection data from the position sensor and the first non-contact sensor. The system also includes a first position calculation unit that calculates the work machine's first position by matching the map data with the detection data from the first non-contact sensor. Additionally, a second position calculation unit determines the second position based on the detection data from the second non-contact sensor. An integrated position determination unit then integrates both positions to ascertain the work machine's overall position.

The work machine control method involves acquiring the detection position of a landmark identified by a non-contact sensor during the work machine's travel. It calculates a first relative distance between the non-contact sensor and the landmark based on the detection position. A second relative distance is calculated using the landmark's registration position. The method then computes a correction value related to the relative distance, which is used to correct the first relative distance, ultimately controlling the traveling state of the work machine based on the corrected relative distance.
