It reminds me of the book "Man of Two Worlds" by Frank Herbert and his son Brian. In it, some crazy inventor guy built his own car, but instead of wheels like any normal car, it had legged robots on each end that carried it. The inventor's son complained that this car was impractical as it couldn't travel as fast as a normal car.
That's a video of the table walking. It would have been super interesting to see a video of the different steps of the optimization process as a 3D animation, but that's a bit too much to ask.
As it indeed says in the second sentence. It's a modification of the design for smoother movement. Which seems to work well since that bottle stayed put.
Interesting that it's made out of laminated bamboo. Often this kind of thing is plywood which is its own aesthetic but I think not as nice (and a nightmare if the plywood is big box store crap and not excellent quality). It's a great, dimensionally stable material but really a hassle to get hold of here in non-bulk quantities. I wanted some bamboo sheets for a knife rack and ended up buying table mats at retail and cutting them down.
That's really cool, I really appreciate how the legs are barely extending beyond the table itself. I wonder how much it could carry, whether it could also be a trunk (someone else already mentioned the Luggage), cabinet, or fridge. (The walk-ing fridge pun was already used in a beer advert)
