Claim 0:
1. An apparatus for expanding a box blank, comprising:
an arm assembly, including:
a base having a surface;
a first arm coupled to the surface of the base through a rotation joint, the first arm having a box blank contact surface perpendicular to the surface of the base; and
an actuator, including:
a body, coupled to the surface of the base; and
an actuator arm coupled to the first arm;

a box blank conveyor, which, in operation, moves the box blank against the box blank contact surface of the first arm of the arm assembly, expanding the box blank, the box blank conveyer including:
a vacuum cup;
a valve to selectively couple the vacuum cup to a vacuum;
a positioner coupled to the vacuum cup; and
a controller coupled to the positioner and the valve, the controller, in operation, causes the positioner to move the vacuum cup against the box blank, opens the valve to couple the vacuum to the vacuum cup, and causes the box blank to move in a second direction against the box blank contact surface of the first arm;

a camera having a field of view including a feature of the box blank;
a controller electrically coupled to the camera, the controller in operation, receives an image from the camera, determines a position of the feature of the box blank in the field of view and moves the arm assembly in a first direction using the actuator based on the position of the feature in the field of view.
