My thought about robotic vertical vehicles.

So many universities, have been trying to create a robotic vehicle that can climb walls. I have seen many types of prototypes, which all basically use an adhesive type wheel. This is a great start! However to complete this amazing attempt, let me give some insight of what will really make it work. \

In the center of the robotic device, just add a propeller that will basically push the device towards the wall. THATS IT.
