A support structure provides two or more axes of intelligent locomotion for a movable object on the support structure. The support structure can include a track system made up of a plurality of identically configured track modules that are connected end-to-end. Each track module can include an elongated body defining a longitudinal axis and having two ends. Each end can include at least one beveled edge and at least one track surface extending longitudinally along the elongated body. The track surface can include a plurality of protuberances arranged in rows that are parallel to the longitudinal axis of the elongated body, and in columns that are perpendicular to the longitudinal axis of the elongated body. The track modules can be connected a power source and include electrical contacts that provide electricity to self-propelled units that travel along the track system.
