This paper presents the design and analysis of hybrid method adhesion mechanism of the Wall Climbing Robot (WCR) by using online Computational Fluid Dynamic (CFD) software SIMSCALE. The simulation is focused on the investigation of the air flows and negative pressure region inside the chamber while calculating the adhesion force by varying the gap height of the chamber and the air flowrate which correspond to the propeller rotational speed. The results of this simulation show the increased in adhesion force by decreasing the gap height. Also, from the result, it is found that there is a limit on flowrate to maintain the adhesion force at a small gap height. The results also show significant increase of force production with respect to the thrust force which is the original force produced by the Electric Ducted Fan (EDF). This shows that the hybrid method can make the EDF to produce much higher force than its normal mode.
