If anyone can optimize Disney’s omni directional walking pad, we’ll be there. I’d give it 3 decades if it goes that way. I’ve heard it’s not like real walking. It feels very slippery. All that being said, you don’t have to wrap yourself in a harness and fight friction to simulate walking like other walking pads. It also seems simple enough, hardware wise, that it could be recreated using preexisting parts/ 3d printing. I’m honestly surprised I haven’t seen a DIY project yet.
