Abstract: A self-propelled unit for movable operation on a support structure along a first axis of movement and a second axis of movement that is transverse to the first axis of movement includes a carrier configured for movable displacement on the support structure. A first conveyor assembly is operable to move the carrier on the support structure along the first axis of movement. A second conveyor assembly is operable to move the carrier on the support structure along the second axis of movement. A light source can be attached to the carrier in an operable mode to provide illumination to an area in proximity to the carrier. At least one power contact is configured to maintain electrical contact between the carrier and the support structure.
