The downhill running of robot in vertical pipe is a special case for robot running inside the whole “U” type pipe, in which case the speed variation fluctuates greatly. The thesis makes a specific analysis of the force situation of the robot running downhill in the inclined pipe, carries out analog simulation of the fluid pressure and speed change of robot with the dynamic grid technique of Fluent, and finally gets the fluid pressure and speed change rules, thus providing theoretical basis for further effective means in the robot speed control.
