Abstract
A method of calibrating positions of wheels in an AGV, the method including positioning a second wheel tangentially on an imaginary second circle centered with respect to a center position in which a first wheel is fixed; driving the second wheel a second distance along the second circle such that the AGV rotates about the center position; determining the second distance based on data from a second wheel sensor device of the second wheel; determining an angle of rotation about the center position based on data from a first steering sensor device of the first wheel during the rotation of the AGV; and determining relative positions between the first wheel and the second wheel based on the second distance and the angle of rotation. An AGV is also provided.
