Abstract: A method for controlling a video camera positioning system includes the steps of controlling a motor for driving a video camera to capture a panoramic frame, dividing the panoramic frame into a plurality of frames, controlling the motor for driving the camera lens to turn to the frame corresponding to an encoded command signal when the microcontroller receiving the encoded command signal, and zooming in the frame by the video camera. Furthermore, a video camera positioning system is also disclosed herein.

Abstract: A support structure is disclosed, which includes plural cylindrical joints. Each cylindrical joint includes a cylindrical joint body having a wire channel for being passed through by a wire, a cylindrical joint head disposed on one end of the cylindrical joint body and having the wire channel, a cylindrical joint socket disposed on another end of the cylindrical joint body and having the wire channel The cylindrical joints are connected one by one by coupling the cylindrical joint to the corresponding cylindrical joint socket and are rotated along the radial direction of the cylindrical joint head.

Abstract: A ball joint structure is disclosed, which includes a socket with a containing opening, a ball disposed in the socket, a cover disposed at the containing opening, a protrusion disposed at an outer surface of the ball, a concavity disposed at an inner surface of the socket, and plural adjustable elastic screws screwed on the socket. The protrusion is moved in the concavity when the ball is rotated in the socket. The ball is gripped in the socket with a force provided by the adjustable elastic screws.
