This skateboard concept lets you travel down stairs almost as smoothly as gliding down a hill. This seems to be the eighth iteration in [PoChih Lai's] attempts to add functionality to a board which will make it the ultimate ride for an urban outing. Check out the video after the break to see just how well he did.
We’ve seen hand carts that use six wheels to make stairs a breeze using a triad of wheels as a single-wheel replacement. This was actually the main concept early on in the design. But the drawback to this method is that the design takes up a lot of room and [PoChih] also made the deck much bulkier to keep you from getting a foot caught in the mechanism. The final design does away with the end-over-end concept and adopts a rocking mechanism. The board hangs from a bar which serves as the pivot between the two wheels. This way the wheels can absorb the brunt of the motions, and the base of the deck can slide across the fronts of the steps if needs be.
We were talking about this here at the Hackaday office and the point was made that this is like YT’s skateboard from Neal Stephenson’s Snow Crash. Did you hear that it’s headed to a theater near you?
