Wall Climbing Bot

There have been wall climbing bots in the past but what makes this particular example special is the technique used to achieve this.

This unnamed robot uses static electricity to hold it self against the wall and suprisingly its qite agile. I cant think of any commercial applications for this technology but im sure the military will scoop it sooner or later.
