Rrobot treading system is designed

all the mobile machine advantages and disadvantages are synthesized

and complex wheels-track is adopted by mobile mechanism.Walking in line

swerving right and left

passing gibbosity

climbing stairs and surmounting groove are realized by the robot.The mobile robot is studied from kinematics

and the passing capabilities of the robot are analyzed in all kinds of circumstance.This kind of mobile robot can be adapted in the exploration

succoring and other complex circumstance.
