A pan-tilt-angle support device allowing fully remote contro of any equipment is provided, giving the photographer o operator the opportunity to adjust the device's pan-tilt- angles about three-axes (x, y, z) for optimum performance fro a remote location by relative rotational precision adjustment about the appropriate axis (x, y, z) by an electric servo o step motor (30) connected to each articulated joint (4, 5, 6) . The interface to the operator could be a remote located devic with a control arrangement similar to a joystick, a hand hel remote control, a PC keyboard or the like, which operates an controls the pan- tilt -angle axis position of the equipment, e.g. an SLR camera, through either electrical wire connectio (21, 22, 23) or through other electrical or radio wave means. |
