Abstract
A dual-axis hydraulic joint system includes a vertical shaft, a horizontal shaft, and a hydraulic system. The vertical shaft allows a yaw rotational motion and the horizontal shaft allows a pitch rotational motion, wherein the rotational motion of the vertical shaft and the horizontal shaft is controlled by the hydraulic system. In doing so, the hydraulic system manages a pressure value within a vertical shaft enclosure that holds the vertical shaft, and also manages a pressure value within a horizontal shaft enclosure which holds the horizontal shaft. The pressure value within the vertical shaft enclosure or the horizontal shaft enclosure is either increased or decreased to determine the rotational direction of the vertical shaft or the horizontal shaft. When used for solar panel direction control, the hydraulic system operates according to feedback received from a light-sensor unit, a first encoding unit, and a second encoding unit.
