An auto carriage and a system thereof are provided to prevent the sliding by executing a feedback operation on a motor through the detection of sliding amounts. Marks are arranged in at least two rows along a traveling route(4) of an auto carriage(2). The auto carriage includes a first detection unit, two or more linear sensors(13,14), a second detection unit, a third detection unit, and a controller. The first detection unit detects the driving amounts of wheels and the variation amounts per time of the auto carriage. The linear sensors detect the marks. The second detection unit detects the absolute position of the auto carriage and the variation amounts of the absolute position based on outputs of the linear sensors. The third detection unit detects the sliding amounts of the auto carriage by comparing the variation amounts of the driving amounts with the variation amounts of the absolute position. The controller controls a motor of the wheels to compensate for the sliding amounts.
