What do you get when you cross this Gripper
and a quadroped like this?
Well, I don't know, you could get a number of things, but, I propose that you could have the makings of a pretty sweet wall climbing robot. Just get 4 of those grippers, mount them on the feet of your quadroped, and alternate "ungriping" one foot while the other 3 are stuck, moving it forward a bit, planting it firmly on the surface, sucking all the air out agin and repeating for each leg. It would not work on smooth surfaces like glass, but deffenately on brick/concrete walls, and maybe even on drywall.
