摘要： PURPOSE:To perform a locally favorable environment adjustment while tracking a worker who works in a fixed range by a method wherein an object sensor is turned in the track direction while following a moving worker, and at the same time, the movement of the main body is not started until the turning angle becomes a specified value or more. CONSTITUTION:A sensor angle alpha is the angle which is made by the center line P and a vertical line, and a specified angle beta is the angle to prevent hunting motion of a main body 3 from happening, and approximately 5 deg. is suitable. When the main body 3 is located directly above a worker 60, both sensors A, B are detecting the worker 60, and the sensor angle alpha is 0. When the worker 60 advances, and both sensors A, B become unable to detect the worker 60, a sensor unit 7 rotates forward until the object sensor B at the front side detects the worker 60. When the moving distance of the worker 60 is short, and the sensor angle satisfies alpha =beta, the main body 3 advances. When the moving speed of the worker 60 is fast, since the sensor unit 7 rotates to follow the worker 60, the sensor angle alphabecomes larger, and it is controlled so that the moving speed of the main body 3 also becomes faster.
