The REX Robotic Exoskeleton 53

ElectricSteve writes "When Robert Irving was diagnosed with Multiple Sclerosis, it was the catalyst for him and his childhood friend, Richard Little, to turn their engineering skills to the task of developing an exoskeleton that was a practical, standing-and-walking alternative to wheelchairs. The result is REX, an exoskeleton made of strong, lightweight materials that is designed to support and hold a person comfortably as he moves. Users strap themselves in to the robotic legs with a number of Velcro and buckled straps that fit around the legs, along with a belt around the waist. While most robotic exoskeletons we've looked at, such as the HAL, augment human motion, this is generally not an option for wheelchair-bound users, so REX is controlled using a joystick that sits at the wearer's waist level." The rig is expected to cost $150K when introduced later this year in New Zealand. Gizmag has an obnoxious timed popover subscription nag, so NoScript is indicated.

        Yeah, I know about the iBOT, but it's still a wheelchair. It's also been discontinued. A modified Segway would of course be permanently upright and much faster.

        I suppose one big problem would be how to get someone in a wheelchair to stand up in a Segway - the Rex and iBot both start in sitting positions.

          I wouldn't agree with the statement "it's still a wheelchair". While it is technically a chair on wheels it solves the vast majority of the problems that wheelchairs have: it can go up and down stairs, it can raise the user to eye level, and doesn't get bogged down in loose terrain. Oh, and it doubles as a chair. I kid but seriously, if you're paralyzed do you really want to get into and out of a robotic contraption every time you want to move somewhere and then sit down and relax?

            "Profit" and "changing people's lives for the better" are often incompatible goals.

          It probably wouldn't off much advantage, I would think that the balance based control system would be somewhat awkward for people with minimal lower body control, and I would guess that having a statically balanced configuration is good for battery life.

          (And I would also speculate that sitting is more comfortable than being strapped in)

        • But the Segway is a modifed iBot.....

          I mean it was designed by the same people. The biggest differance is that you stand in one [which is hard for wheelbound people] and in one you sit. I guess one could strap somebody in a standing posistion but I would think that would be harder.

          iBot is a cool technology, but I understand it is dying a slow death because the extra value really does not offset the extra costs [expensive, limited range. And when a electric wheelchair runs out of juice somebody can still

          The iBot was more than just a wheelchair. I worked for the company that makes them, and i have seen first hand just how amazing it really is. Independence ot climb stairs and reach high cabinets, as well as the ability to navigate on rough terrain. The iBot may start in a sitting position, but it navigates on 2 wheels in the standing position just as well!

      Because it can't really do much that a power wheelchair can't already do for less money, and requires doing stuff like balancing on top of those function-impaired sticks.

      Or, possible, wheelchair-bound people just don't want to look like dorks [].

      I've always wondered why the Segway wasn't adapted for wheelchair-bound people.

      Just a quibble, but it is tiring to stand in one place for long periods of time. I imagine even more so for someone whose leg muscles have atrophied.

      And if you're going through the effort to strap them into some sort of frame to take the weight off their legs, why not just give them a chair to sit in in the first place.

      A segway doen't give many benefits over a electrified wheelchair; and the strap-in/stand-up procedure would be pretty complicated, so I don't belive that would be really usefull.
    • Dean Kamen's original intent was to build a 2-wheel balancing wheelchair, but unfortunately the global market for that doesn't justify the development costs. So he tricked the investors into paying the development costs for the Segway, knowing most of the technology could be easily transferred to the wheelchair.

There needs to be a huge government investment in technology similar to this. Applying Laissez-Faire to this community is fucking cruel. Also, how much of the 150k is for parts? How many hours go into making one of these devices? What you're going to end up with is a lot of people who use wheelchairs are going to want one of these de

This thing, in it's current form, is probably only suitable for specialized tasks that require standing. You could argue that most tasks require standing, but I'm sure

I am not saying you shouldn't, I just don't see the cost/benefit if the idea is that people will get these expensive machine then to work in some low paying jobs sharpening knives or whatever.

      It's a bench top belt sander.

      Also, I'm not sure I can put a price on standing, and reaching things that you can only reach while standing. $150k sounds pretty good if I'm otherwise stuck in a wheelchair.
