In mechanics kinematics, Jacobin matrix may be calculated and simplified by vector constructing; Inverse solution and its restricting condition be given; Forward solution be solved by new-raphson method. The method need shorter time than optimization and has a lot of advantages in applying program; some relationship of velocity, acceleration, force and error of mapping from input to output have been given. Analyzing of theory base these researches.
