There are many problems to be solved in study on six-legged wilking machine. Some problems are approached in this paper We present two practical gaits and study the spatial pantograph mechanism used as walking mechanism. In inverse kinematie research
we obtain the singnlar positions
and gave the way with series expansion of it's filling. Based on the kinematic characteristics of walking machine we do optimal
design of leg mechanism. From the point of view of engineering design we analyse the motion coordination that should be noticed and present the solution.
