The downward force generated from these propellers is enough to support the vehicle driving on a vertical wall and “theoretically even on the ceiling,” the researchers say.

The two steerable propellers allow the VertiGo transition from wall to floor and floor to wall, as you can see in the video below. One propeller applies force toward the wall, while the other forces the vehicle in an upward direction.

The propellers provide enough thrust to ensure the robot will “stick” to walls even if they have indentations and imperfections. So, what exactly is the purpose of this amazing, wall-crawling robot?

Disney Research scientist Paul Beardsley told IEEE Spectrum that he wasn’t at liberty to discuss why the company was interested in researching and developing the VertiGo. “But just speaking in general, one can imagine that robots with lighting effects could be useful for entertainment effects or for wall games,” he told them.
