Abstract
A moving apparatus has a body, and has at least a pair of wheels, a control unit, a direction measuring unit and at least a pair of encoders installed on the body. The direction measuring unit coupled to the control unit measures the direction of the body, and the control unit obtains a first direction variation according to the direction information. The pair of encoders coupled to the control unit measure a speed of the pair of wheels, and the control unit obtains a second direction variation according to information of the speed. The control unit compares the first and second direction variations to determine whether the direction measuring unit is temporarily dysfunction. Based on the result of comparison, the control unit applies the information provided by the direction measuring unit or the pair of encoders to obtain the current direction of the body.
