Gecko-like bot: It can climb walls

Meet a bot that can climb up trees and walls.

From MSNBC:

Researchers have built a tank-like robot that can climb smooth walls with the ease of a gecko scurrying about in the middle of the night. In fact, the robot was inspired by a scientific explanation for what makes gecko feet so sticky.

The robot could find use in applications ranging from inspections of pipes, buildings, and nuclear power plants to search and rescue missions.

Its tank-like feet are inspired from the millions of tiny, hair-like toe pads on gecko feet that allow the lizards to scurry up trees, walls, and across ceilings without falling down.
