Gecko Lizard Robot from Stanford (StickyBot III)

Stanford University has invented a lizard robot, an improved version of its previous prototypes (Stickybot), Stickybot III. StickyBot 3 is a lizard robot (gecko) which can climb up windows thanks to its special suction cups installed on each of its feet. These suction cups are not adhesives in the normal sense but rather are made up of mini particles which are able to cling to material by using van der Waals forces. The genius of this concept lies in the fact that the feet can stick to the window and even come off without force (unlike sticky tape, for example) allowing the lizard robot to climb up windows like a real gecko. http://www.youtube.com/watch?v=0y2MVuSyQlg via botjunkie and hackaday
