Recall of Segway Announced by CPSC 569

mshiltonj writes "The Consumer Product Safety Commission has announced a voluntary recall of the Segway human transporter. The hazard is that under certain operating conditions, particularly when the batteries are near the end of charge, some Segway HTs may not deliver enough power, allowing the rider to fall. This can happen if the rider speeds up abruptly, encounters an obstacle, or continues to ride after receiving a low-battery alert."

    As much as I love seeing rich people fall on their faces, I hate seeing technology fail because of poor testing.

    Why didn't this come up before now? Because ravenous marketing monsters couldn't wait to start selling "THE NEXT BIG THING".

    Even if they were reasonably priced, I can't see what they're really good for anyway. They're too fast for sidewalks, too slow for streets and let the world know you've got more money than sense!

    Maybe they should put training wheels on all of them while they are in recall?

    You know, that started as a joke in my head, but you do have to wonder why they didn't put a small third wheel on there somewhere always touching the ground but on a hing so that it would only actually bear weight if the thing tipped too far.

    Then again, I suppose the market droids couldn't have pushed it so hard as the next big thing if it didn't just have two wheels... Hard to look like an adult when you're basically whizzing around on a tricycle.

    I don't find it interesting that a software upgrade fixes the problem.

    Software upgrades are the cheapest fix for any system problem. This is why they are almost always required by devices. We (companies, not specifically Segway) can ship products early with solid hardware and must less solid software because the cost of fixing problems in software are so minimal.

    This software fix probably just shuts down the scooter earlier before the battery runs all the way out. A few cars do the same with gas so that people are driving at 70mph don't loose power breaks and stearing when the engine starts studdering.

    Hardware fixes can often cost more then direct replacement of the product. A simple printer circuit board rework could cost $50 each to just disassemble a product, cut a trace and reassemble it. That doesn't include the cost to ship the product back to the manufacture or to a rework house somewhere in the US.

    Flash is cheap and almost all companies use it to fix sw problems in the field and work around hardware problems.

    Well, the point is that the Segway is supposed to do all the balancing for you.

    Honestly, the first time I saw Segway I thought, "What happens when you're chugging up a hill and the batteries give out?" It's inherently unstable, unlike a bicycle there is no gyroscopic force to aid the rider in maintaining balance.

    The software upgrade probably just gives the Segway less optimism about its battery life, providing a more aggressive alert when the battery reaches a certain level.

    The funny thing, is there is no way for them to stop the Segway if the rider doesn't cooperate. You lean forward to go foward. If the Segway want you to slow down, it can only do it by letting you fall over.

    remember kids that the majority of americans & the congress & senate voted to go after iraq...also bush isn't the 1st or only one who said iraq had wmd and saddam was a threat...remember these?

    "One way or the other, we are determined to deny Iraq the capacity to develop weapons of mass destruction and the missiles to deliver them. That is our bottom line."
    President Clinton, Feb. 4, 1998

    "If Saddam rejects peace and we have to use force, our purpose is clear. We want to seriously diminish the threat posed by Iraq's weapons of mass destruction program."
    President Clinton, Feb. 17, 1998.

    "Iraq is a long way from [here], but what happens there matters a great deal here. For the risks that the leaders of a rogue state will use nuclear, chemical or biological weapons against us or our allies is the greatest security threat we face."
    Madeline Albright, Feb 18, 1998.

    "He will use those weapons of mass destruction again, as he has ten times since 1983."
    Sandy Berger, Clinton National Security Adviser, Feb, 18,1998.

    "[W]e urge you, after consulting with Congress, and consistent with the U.S. Constitution and laws, to take necessary actions (including, if appropriate, air and missile strikes on suspect Iraqi sites) to respond effectively to the threat posed by Iraq's refusal to end its weapons of mass destruction programs."
    Letter to President Clinton, signed by Sens. Carl Levin, Tom Daschle, John Kerry, and others Oct. 9, 1998

    When moving, a bicycle is inherantly stable, as there are two aligned gyroscopes keeping it going forward. It's only unstable when not moving or nearly not moving. Even when stopped, it is only ustable perpendicular to the direction of motion.

    The segway, on the other hand, is ALWAYS unstable along the axis of motion, and the farther you get away from the stable point, the more force it takes to bring it back to being stable.

    "Segway's Human Transporter, the self-balancing electric scooter that has kept technophiles abuzz for the last two years, ranks among the best-selling items on Amazon.com's Web site, the online retailer said Monday." Anybody else remember claim last December [usatoday.com]?

    According to Wired [wired.com], Kamen had predicted he'd be "stamping out 10,000 machines a week" by the end of 2002.

    My car doesn't fall over if it runs out of gas.! :-)

    If this thing is supposed to revolutionize the way entire cities are built I guess that means they're going to have padded sidewalks!

    Clearly this problem should have come up during the design and prortype phase? Shouldn't it have?

    LOL!

    When I leave on a trip, be it short or long, I always check my gas level and make sure my lights, brakes, etc. work. It's common sense.
    Falling off aside, if my battery/alternator is bad and it's a rainy night, it's my own fault if I get stranding in outer Bogonia. Same goes for fuel, brakes, and radiator.
    This issue does point out a flaw with some very reasonable solutions (slow and stop upon low battery or even a third wheel stabilisation to allow the gyros to be turned off-drops/extends from the back).

    Too much fodder for the basshers here.

    Getting elected to the presidency does not give him immunity to questions, criticisms, or even mockery from his constituents.

    But what does he win if he gets appointed to the presidency instead?

    Recall it because it fails to work if someone keeps going AFTER it gives them a low battery warning???

    That's like saying they should recall cars because you could run out of gas on the highway and die, even though they have a handy gas gauge and some put on a little light to tell you when you're pretty much empty. I don't think they should recall something because of user stupidity.

    Now I'm not a Segway advocate by any means (I think they're ridiculous), but this is stupid.

    Is recall fever spreading?

    Slate did a review of the Segway a few months ago, and one of the issues raised was that the low battery indicator was impossible to read (you needed to bend over it and shield it from ambient light with your hand to read it). Piss-poor design that.

    Other articles on the recall indicate that gyroscopes are impacted first when power drops below optimum. The scooter pitches the rider over on their head. Again piss-poor design. Imagine if your motorcycle were designed to handle a low fuel situation by locking your anti-lock brakes while you're at highway speed.

    Kamen has a deserved reputation for producing rough prototypes that he considers market ready, when in fact they are optimistically 25% of the way there (The folks I work with know this from bitter experience).

    Very few companies would buy a Kamen design a second time, and woe unto the engineers sentenced to clean it up into a marketable product.

    "Trying to eliminate Saddam... would have incurred incalculable human and policital costs. Apprehending him was probably impossible... We would have been forced to occupy Baghdad and, in effect, rule Iraq... there was no viable 'exit strategy' we could see, violating another of our principles... Had we gone the invasion route, the United States could conceivably still be an occupying power in a bitterly hostile land."

    Everyone makes mistakes. Hell, just a few minutes ago I got an ICQ from my sister, who was frightened by the noises her CD drive was making. Well, it turned out she put a second disk there without taking the first one out. :) She isn't stupid, she knows very well CD drives don't work with 2 disks, she knows they don't work with floppies either, she knows how to burn CDs, etc.

    She just didn't notice that because the computer is under her table.

    That's why it's important to design fool-proof products. Not because all people are fools, but because all people make mistakes!
