1. An apparatus for overlaying a media stripe onto a media stripe previously applied to a surface comprising:
a mobile frame housing controls; an applicator head comprising
a first sensor which casts a first cone of vision onto the surface, the first cone of vision positioned tangentially to a first edge of the media stripe previously applied to the surface,a second sensor which casts a second cone of vision onto the surface, the second cone of vision positioned tangentially to a second edge of the media stripe previously applied to the surface, anda media nozzle adapted to spray media overlaid on the media stripe previously applied to a surface, the media nozzle positioned at a distance from the first and second sensor; and an extendable arm having one end attached to the frame and the other end attached to the applicator head, wherein when the applicator head is moved along the media stripe previously applied to the surface and either the first or second cone of vision from the first or second sensor is no longer tangential to the first or second edge of the media stripe previously applied to the surface, the first and second sensors communicate with the controls which instruct the extendable arm to reposition the first and second sensors such that the their respectable cones of vision center are again tangential to the first or second edge of the media stripe previously applied to the surface. |
