Method and apparatus for labeling of support structures

An apparatus for labeling support structures, comprising:

• a chassis having a locomotive assembly;
• an effector assembly having a first end coupled to the chassis and a second end movable relative to the chassis;
• a label modification unit at the second end of the effector assembly, the label modification unit including an image sensor;
• and
• a controller coupled to the locomotive assembly, the effector assembly and the label modification unit, the controller configured to:
• obtain label modification data defining a location of a low powered display relative to a reference feature on a support structure for modifying content displayed by the low powered display;
• control the locomotive assembly to travel to the support structure;
• detect the reference feature via image data captured at the image sensor;
• control the effector assembly to place the label modification unit at the location relative to the reference feature;
• and
• control the effector assembly and the label modification unit to modify content displayed by the low powered display.
