A. Dixon is controlled by two softwares, one is mechanical software to control orbital motion, and the other is software to control shooting. This process is very complicated, and Ole can accurately control the track operation with Dragon software, and control, shooting and synthesis can be done in one go in Dragon software. Ole control chip is jointly developed by Dragon Software Company. B. Dixon can only move in XYZ three directions, but can't pitch and yaw. Moreover, the arm is less than one meter long and the range is very small. The camera moves back and forth on the Y axis, so the camera cannot be extended to shoot in the scene. Y axis will block the camera's line of sight and block the light. Ole's six-axis orbit can perfectly realize a wide range of XYZ axis space shooting, pitching and yaw rotation.
