Robot Chairs

Chairs may be among the most useful inventions known to humanity, but that doesn’t mean that a clever engineer or two can’t improve on the idea. As proof, we offer you this list of robotic chairs that do much more than provide a place to put your rear in.

You may have already heard of the “take a seat” chair designed for libraries. Each chair has an RFID card reader inside. When the chair is activated, it follows the user holding the card around the library, providing an ever-present place to sit while searching through the stacks. When the user leaves, the chair returns to its docking station to power up and wait for the next patron.

Perhaps you’re saying, “I don’t want a chair that follows me, I want one that follows other people while I’m in it.” Say no more: we found not one, but two walking chairs. The first legged chair, dubbed the WL-16, was designed jointly by a team at Tokyo’s Waseda University and a Japanese robotics company called Tmsuk. It uses two legs composed of several rams and a plate that acts as a foot. It is capable of maintaining its balance under the shifting weight of a rider and walking up a flight of stairs with a relatively gradual grade. It is radio controlled, but the joint team is working on installing a joystick controller on the chair.

The second walking chair we found, the Hubo FX-1, appears far more substantial: it also has legs, but they look a lot more like human legs with their knee and ankle joints. It also stands at an impressive 2 meters high, and is capable of lifting as much as 220 pounds. It is controlled with a joystick by the rider, but relies on various built-in sensors to maintain its balance and an awareness of the local terrain. Its designers at the Korea Advanced Institute of Science and Technology have not yet been able to build one with internal power, but they are attempting to fix that in the next model.

If those chairs are too functional and not artistic enough for your taste, check out this self-assembling chair by students at Cornell University. The chair is able to collapse into many pieces, then the pieces move toward each other, reassemble, and stand up as fully functional chair once more. It serves no practical purpose, but the concept of self assembling parts is intriguing. If you know of any other chairs that do neat tricks, let us know.

  1. I have to say, the first one seems to be the most practical out of the four designs shown here. And the best part is that the applications are not just limited to a library! Beware the swarms of robotic chairs :P

  2. that second last one looks like it needs to pee! rofl

    i have a chair that does a neat trick on visitors. just like the last one it falls apart but only when some sits on it ;)
    i wonder how long till the detect human function is added to trigger the disassembly… could be fun to leave in a public place =D

  3. Ok…. so you’re posting slashdot posts from over a year a go (when I stopped looking there) and on tap of that, these are not hacks.

    What is happening to hackaday?

  4. The product Laurier Furniture 6566-Time Square 65 Side Chair is made from top quality maple veneer. The product is very comfortable to use and easy to clean. It is available in Raffia, Andora and Marron finish. This is the best white glove service on the market. Just logon and buy the best product from Thanks for incredible one-place furniture shopping virtual place. And what else FREE SHIPPING with no sales tax. Isn’t it mind blowing!!

  5. How can you go wrong with a $640 dinette chair WITHOUT robotic capabilities? Seriously, it’s not even solid maple! Anyone who buys one of those has much more money than brains, but hey: they’ll be getting “then best of the best.”
