A robot capable of moving on a vertical wall using thrust force

A robot capable of driving on a vertical wall using the thrust force has been developed. It has the propeller and its thrust force is inclined to the wall side to produce the frictional force between the wheels and wall surface. The effect of strong wind on the robot is very important on the wall of high-rise buildings. The minimum required thrust force and its angles are obtained for the assumed wind gust by the computer simulations.<
