An articulating head that includes a linear movement assembly. There is a pivot plate that includes a first connection point. There is a pivot arm rotatably attached to the pivot plate. The pivot arm has a second connection point. There is a linear movement assembly mounted to and between the first connection point of the pivot plate and the second connection point of the pivot arm to cause rotation of the pivot arm about the pivot plate. The linear movement assembly comprises a threaded rod mounted as a screw, a nut which threads onto the screw and a motor interconnected to one of the screw and nut to cause motion between the screw and the nut. The screw and the nut are mounted between the pivot plate and the pivot arm, whereby the motion induced between the screw and nut causes the pivot arm to rotate about the pivot plate. |
