Abstract
Abstract A method of moving and guiding a cart on a course, comprising the step of burying magnetic elements under a ground surface of the course to form a marker line in a moving direction of the cart. The magnetic elements comprise different poles defining one of S-shaped and zigzag-shaped routes and a predetermined route of a cart movement. A pole polarity is sensed for switching movement of the cart between the one of S-shaped and zigzag-shaped routes and the predetermined route for moving the cart along the marker line.
