3 TTR The four wheeled, two propellered VertiGo robot drives up walls

VertiGo wheeled robot isn't stopped by walls

In "ground mode" the rear prop is angled perpendicular to the ground, providing enough horizontal thrust to carry the machine across a variety of terrains. Upon reaching a wall, however, the front propeller kicks in and tilts upwards, pulling the front end of the robot up that wall. The rear prop continues to push the back end forward until it's also up against the wall.

From there, the VertiGo can roll vertically across the wall on its wheels, with a partial towards-the-wall tilt of the propellers pushing it in, so it doesn't simply fall off. Because it doesn't rely on suction like some other climbing robots, it doesn't require smooth, even wall surfaces with which to create a seal. This means it doesn't have a problem with walls made from brick and mortar, for example.
