ABSTRACT:
A base support for a moveable object, particularly an amusement ride employing a stepping motor and stepping motor controller to move the object in fine increments. The base support is attached to an upstanding mounting member. An amusement ride is attached to a first support structure connected to a base member. The support structure is operatively connected to a worm gear assembly and motor driven worm gear disposed between the base member and the support structure to effect movement of the amusement ride about a predetermined axis. The worm gear is driven by a stepping motor. The stepping motor is controlled by a stepping motor controller to control incremental movement of the amusement ride. A second worm gear assembly can be interposed transversely between the first support structure and a second support structure to effect movements of the antenna about a horizontal axis. A second stepping motor and second stepping motor controller are used to drive the second worm gear and effect incremental movement of the amusement ride about the horizontal axis.
