A cart that follows a transmission module based on position information of the transmission module and a method for moving the cart are provided. According to an embodiment of the present disclosure, the cart accumulatively stores the position information of the transmission module and generates a moving path based on the position information of the transmission module and moves.

A cart and rack assembly for transporting a planar material includes a rack and a cart. The rack includes a frame coupled to a base. The frame has an upper portion and a lower portion. The upper portion has a first width, and the lower portion has a second width. The cart is configured to reversibly receive the base. The cart includes a guide member configured to guide either of the base or the cart into a predetermined position when the base is received by the cart. The assembly further includes a bracket having a first end and a second end which is configured to selectively secure the planar material to the assembly. The base has a series of apertures configured to accept the first end of the bracket. The second end of the bracket is configured to be selectively coupled with the upper portion of the frame.
