Abstract The transverse cutting mechanism is regarded as the most important part in transverse pavement system of the checkerboard paving robot and it will directly affect the robot's operation. This research aims at designing a new system which is appropriate for the desert working environment and can take the cutting check task. In the paper, the computer emulating technology is applied, and by the three-dimensional modeling by Pro/ENGINEER software, we can observe whether interference exists or not. Besides, the speed and displacement parameters of the main parts of the cutting system are given by the dynamics emulation by ADAMS, which theoretically assures the feasibility and appropriateness of the cutting mechanism. At last, the result of the experiment shows that the cutting mechanism can cut the straw strand as designed.
