Abstract
A self-traveling vehicle without requiring guide wire for travel is provided which allows a change of a traveling course with little expense and labor for reconstruction. Such self-traveling vehicle comprises a storing means for storing a travel road to be traveled, a receiving means for receiving a signal from a satellite and a calculating means for calculating a current positional information based on the signals from the satellite. A controlling circuit for controlling the traveling drive and steering wheel drive provided in the vehicle controls the vehicle in such a manner as to travel on a predetermined set road by verifying the current positional information and the road to be traveled.
