Oh sure, we've heard about wall-climbing robots before. They s-l-o-w-l-y make their way up vertical surfaces to clean or spy from them. And that's all well and good. But why crawl when you can haul ass?!
A Swiss collaboration between Disney Research and ETH has created a prototype they catchingly call VertiGo. As you can see in the video below, it's pretty quick and agile on the ground. And then using independently titling twin propellers, it makes the transition upwards. Those same thrusters reposition to pin it to the wall, allowing it to race around—even on non-smooth surfaces—where others can't.
Although it's still just a concept and we're not sure if/when it may make the transition to an actual product for us consumers, we're almost as excited about its prospect of doing so as an actual, real hoverboard (which also uses fancy propellers).
