Because of mechanism parameters unknown and complicated mathematical calculations,it is very difficult for us to identify screw system independence. However,Klein projective geometry theory is used to discuss screw system dependence in this paper. As a result,it is very easy for us to identify screw system dependence by Klein projective geometry theory,so the problem of discriminating input selecting reasonability is solved.
