This paper introduces the softwares developed for computer aided study on kinematics of the six-leg walking vehicle to meet the needs for the walking vehicle computer simulation.It can be used to analyze kinematics of six-leg walking vehicle and walk-ing mechanism.After the kinematics analysis the picture display block can be used to realize the simulative walking display on the rough terrain.The display block is developed with 80286-macro-assembly and can be interfaced with FORTRAN to realize graphic functions.It is conveniently used to mechanism display and other purposes.
