Abstract
In order to improve the cleaning efficiency and adsorption capacity, a wall climbing robot system which provides adsorption force by the reverse thrust of the ducted fan is proposed. Firstly, by analysing the reverse thrust adsorption conditions, the minimum thrust required to satisfy the robot motion is 7.54N. Then, the thrust is measured by the improved force line translation theorem, and the optimal installation angle is obtained by modeling and simulation. The thrust force of the ducted fan is analyzed according to the slipstream theory, and the lift force provided by the ducted fan can be used as adsorption and reverse thrust. Finally, the fluid model of the adsorption system is simulated to analyse the pressure distribution of the adsorption system and the stable adsorption conditions of the wall climbing robot, and the correctness of the fluid model distribution of the adsorption system is verified.
