The self-propelled camera positioning device includes a camera support unit having wheels and a camera.The self-propelled camera positioning device also includes a drive unit coupled to the camera support unit. The drive unit includes at least one drive roller, two guide rollers positioned adjacent to the at least one roller. The guide rollers are biased against the first side and the second side of the center rail. The wheels on the two outer rails are positioned on the two outer rails. The camera support unit is moved along the track to define information of the motion. This information is stored. A scene is shot by operating the camera while moving the camera support unit along the track as a function of the stored information of the motion.
