Abstract
An armored vehicle is provided with a gun mounted upon its top deck which gun is capable of rotation through 360.degree. C. about a vertical axis. The gun is also simultaneously elevatable through an angle of about 70.degree.. Located upon the deck are a plurality of barriers (some fixed and some conditional, e.g., opened hatches) which the gun must avoid during its rotational movement. The apparatus of the present invention includes a programmable read-only-memory which stores the location and height of each of the barriers on the deck. A computer continuously checks the position of the gun against the location of each of these barriers and provides signals which prevents the gun from moving into forbidden zones which include the locations of these barriers. As the gun approaches any of the barriers a signal is generated which causes the gun to be elevated from its normal path (if necessary) and lifted over the barrier. The distance from the barrier at which the upward movement of the gun starts is determined by the speed of movement of the gun, the elevation of the gun, and the height of the barrier. Thus, if the gun is moving slowly and the barrier is relatively low the gun can …
