An automated motorized assembly may be utilized to move a laser reflector on inside or outside surfaces, along edges of barrel shape structures. The laser reflector may be used to reflect laser signals back to a laser tracker metrology system locked in on the laser reflector. The laser tracker may follow the laser reflector as it moves along an edge of a barrel shape structure, acquiring circumferential data. The laser reflector may be moved to different positions to enable obtaining different circumferential rows of data. The automated motorized assembly may comprise a movement component that ensures consistent, continued, and/or tight movement along the traversed edge. The movement component may comprise a plurality of wheels and/or rollers, and one or more motors for driving at least some of the wheels and/or rollers. The automated motorized assembly may be controlled by user input, which may be communicated wirelessly.
