An apparatus and method of directionally controlling a movable partition includes providing at least one roller assembly (344) and a steering actuato r (350), coupled therewith, to a portion of the partition. A controller (330) may be used to control the steering actuator (350) and thereby select, or change, the orientation of the roller assembly (344) with respect to the partition. In one embodiment, one or more sensors (346) may be used to determine the vertical orientation of the partition including whether the partition, or a section thereof, is substantially plumb. If the partition is substantially out of plumb, for example, if a lower edge of the partition is laterally displaced relative to an upper edge of the partition, the controll er and steering actuator may cause the at least one roller assembly to direct t he partition, or section thereof, in a particular direction until the partition , or section thereof, becomes substantially plumb. |
