Take Spider-Man’s wall-climbing abilities, put it in robot form, and you get Disney Research’s VertiGo. Using two tiltable propellers, this four-wheeled robot can easily transition from horizontal movement to vertical climbing. That’s right, its dual, maneuverable propellers give the VertiGo its thrust, while one pair of wheels provides steering capabilities. The horizontal to vertical transition is achieved when the rear propeller pushes the robot forward while the front propeller thrusts upward, flipping it up a wall. Once on the wall, the force of air created by the propellers presses the robot firmly against the surface, preventing it from falling off, while slightly tilting the propellers can give it either forwards or backwards thrust.
