This paper focuses on the obstacle of the round edge convex platform in the factory,and plan the obstacle movement of the double-track-inspection robot over the round edge convex platform.The process of the robot through the obstacle is regarded as quasi-static process.From the perspective of static mechanics,three key stages of stability analysis model are established.Through numerical simulation,it obtained a relation between equivalent support force,epuivaleuce friction force and the elevation angle of robot,and a theoretical basis for slippage stability of D...
