Forest operations environment is very complex , the ground soft soil , swamp or mud can easily slip and variety of trees through the traveling is more difficult with excellent driving performance , in order to enable the robot to special ground environment and poor forest fire maneuverability , stability and reliability , as well as a good climbing and climbing obstacle capability , the paper proposed crawler mobile robot walking mechanism solutions obtained , according to the land use experience in the design of the robot and the robot needs to reach the performance indicators , Lin tracked robot main body parameters and UG software virtual prototype model of forestry tracked robot . With the development of virtual prototype technology , designers can simulate any complex environment through the computer , and fast , economic and effective model of the tracked vehicle kinematics and dynamics simulation analysis , validation , evaluation , improvement Lin tracked robot design play a huge role . Application simulation technology can compare several designs and optimization , shorten the development cycle , and saves the cost of the study , virtual prototyping technology has become an important technology research forest fire fighting robot . Differences due to the characteristics of the crawler and wheeled sports , with a focus on the forest Tracked robot motion process dynamics analysis , were established linear motion and steering movement model for steering the course of the campaign , using Matlab / Simulink simulation analysis . Typical landforms crawler robot working environment according to Lin , the kinematics analysis, verify the robot in typical terrain through sex , and the design of a robot across an obstacle course of action planning algorithm . Finally elaborated dynamics simulation analysis the software ADAMS spoon modeling theory and simulation analysis process , UG and ADAMS interface module , the virtual prototype model was imported into the analysis software , and motion constraints of the dynamic model of driving straight the simulation of an ideal simulation platform , come to the simulation of virtual prototype traveling in a straight line speed , acceleration , and a variety of force and torque graph for the future to continue to study the characteristics of the virtual prototype simulation platform laid a foundation.
