Nobody Asked for a Crab Chair

• Why do so many of the demo videos of this crab chair show no people sitting on it? Is this chair not for sitting?

• “we should never try building new things because they get peoples hopes up” this is such a moronic attitude to have that seems more and more common. its the harrison bergeron-ification of the world

• > They’re over-designed, cost prohibitive and generally out of touch with the realities facing most would-be users. ... Unfortunately, they very rarely translate into real world benefits for people like us.

  Shortly before the Solo Stove came onto the market, I met some of the inventors at Maker Fair in Menlo Park, CA. They were part of a group that was trying to engineer a low-smoke stove for indigenous women who spent most of their time cooking.

  Instead, the women didn't use it but the men used it in the evening to stay warm.

• I didn't before, but now it exists I want one. And I have (mostly) working legs.

  Though I do wonder if it would be more stable with more legs (6 perhaps), as natural crabs have, as a four leg design will result in a lot of time when the centre of mass is in an inconvenient place with respect to the three legs currently on the ground (I'm assuming it moves slowly enough that it is rare more than one leg is raised). Unless the technicalities of more legs would make it worse in ways less convenient than the balance bonus.

• Similar to "concept cars", these kind of things are never really made to be built. It's unfortunate if that sometimes takes attention away from actually making a better product.

• >Let’s be clear: if I could have a free crabchair tomorrow, I’d be out the door, in the line to pick up my new robot legs before I knew where to go.

  So you're asking for a crab chair?

  Jokes aside, yeah, it's expensive and likely impractical, but exploring the solution space is what this prototyping is for

• What are they going on about? I showed this to my seven year old who is wheelchair bound and she asked me when she’s getting her robot legs. She’d absolutely love to have a crab leg chair that could get her up and down the stairs without having to transfer from her wheelchair to her stair lift. Move up and down a little so she could reach something out of a cabinet instead of having to ask big sister or mom and dad for help a hundred times a day.

  You have to build proof of concepts before you can ever even think about mass producing any sort of product, I feel like that’s obvious?

• I really dislike attitudes like the author's. I think it's great and important that people and companies spend considerable amounts of their time and money exploring the limits of design and what's possible, even if the concepts produced have little direct, practical use today. That kind of speculative R&D can lead to great things and who knows, maybe in 20 years it will lead to something amazing that will benefit a great deal of people.

  Trying to pooh-pooh the ideas of tomorrow because they don't immediately solve all the problems of today is just terrible, short-sighted thinking.

  And on a more pedantic note, obviously someone asked for it, else it wouldn't have been made at all. What the author really means is "I didn't ask for a crab chair".
