The transverse cutting mechanism of the checkerboard paving robot, which directly affects the robot's operation, is regarded as the most important part in a transverse pavement system. This research aims at designing a new system which is appropriate for desert working environments and finishing cutting the rope of straw. In this paper, computer emulating technology is applied, and with three-dimensional modeling by Pro/ENGINEER software, can observe whether or not interference exists. Also, the speed and displacement parameters of the main parts of the cutting system are given by the dynamic emulation by Automatic Dynamic Analysis of Mechanical System (ADAMS), which theoretically assures the feasibility and appropriateness of the cutting mechanism. Finally, results of the experiment shows that the cutting mechanism can cut the straw strand as designed.
