Po Chih Lai‘s 8-wheeled skateboard, the Stair-Rover, allows riders to glide down stairs through the use of independent v-shaped articulated arms mounted to the trucks. For Â£170 (approximately $258 USD) you can get your own stair-rover through Kickstarter. It looks quite cool going down the stairs, and I like the look of the trucks. They remind me of the articulated wheels of the Mars rovers. I briefly considered buying a stair-rover, but then thought better of it, since I don’t actually skateboard.
