The present invention discloses a five-degree-of-freedom hybrid robot with rotational supports, wherein, a first fixed shaft seat is rotatably connected to each of two ends of a first rotational support through a revolute hinge respectively; a second fixed shaft seat is rotatably connected to each of two ends of a second rotational support through a revolute hinge respectively; one end of a first length adjustment device runs through the first rotational support, and the other end is fixedly connected to a moving platform; one end of each of the second length adjustment device and the third length adjustment device runs through the first rotational support and is then connected to the moving platform respectively; middle portions of all the first length adjustment device, the second length adjustment device and the third length adjustment device are hinged onto the first rotational support respectively; and, one end of a fourth length adjustment device runs through the second rotational support and is then connected to the moving platform, and the middle portion of the fourth length adjustment device is hinged onto the second rotational support. The present invention effectively reduces the number of hinges, save the manufacture cost, and exhibits good manufacturability.
