I have seen Mecanum and Omni wheels in industry quite a bit lately, and usually not in contact with the floor (as shown in the OP). My favorite use so far was at a water park, where omniwheels were used on a platform, much like the picture in the OP, to move around the big family water rafts. I would liked to have taken a picture, but I liked more to not have taken a camera on a water slide.
