For the new development of robot in the space

a compact and dependable machine should be used in the robot manipulator.It is fit for worm gearing used as the driver to grasp for the advantage of simple motion and drive direction which could be changed.Aiming to overcome the worm gearing adaptability problem in the space

the install
