A moving platform/target system (10) for traveling along a predetermined path. The moving platform/target system (10) includes a track (14) defining a predetermined path and a platform (12) engaging the track (14) for movement along the track (14). The platform (12) includes a housing from which wheels (22) extends from opposite sides thereof and facing parallel to the track (14). A guiding device (26, 28) extends from the housing and engages the track (14), retaining the platform (12) in alignment with the track (14). A power circuit (62, 64, 66, 68, 70) is positioned within the housing and is connected to turn the wheels (22) and impart motion to the platform (12). A sensor (32) senses a position of the platform (12) and pauses the forward motion upon sensing a predetermined position along the track (14). The sensor (32) constantly transmits a position signal which is reflected back towards the sensor (32) upon passing of reflectors (16) positioned along the length of the track (14) wherein movement of the platform (12) is ceased for a predetermined time period upon receipt of a reflected signal. The motion of the platform (12) may also be ceased in the same manner using a second sensor (84) and additional reflectors. Furthermore, the pause time of the platform (12) is adjustable as its speed. Control of the platform's movement may be remotely through a transmitter device (126) and the platform (12) may also house a second motor (122) for moving the platform (12) in a forward, reverse, left and right direction.
