For the northern half of the world it's almost ski season, and thus a curious time to debut a pair of devices that allow skiing in the summertime. Nevertheless Nissan and Japan's National Institute of Advanced Industrial Science and Technology are introducing this pair of two-wheeled, self-balancing devices. Lace up your fresh New Balance kicks, grab onto the handlebars, then hop on to go for a ride. Each one detects weight shifts and motors itself in the direction you want to go -- or at least the direction you're leaning. They don't look particularly stable nor safe, but they could enable some sweet concrete hot doggin' in the summertime -- and some sick splits if you don't have your snowplow perfected.

Yeah, we've seen a self-balancing unicycle before, but the brand new U3-X from Honda takes it to another level. A creepy-sterile, awesomely futuristic Honda level, to be precise. What makes the U3-X particularly interesting is it has the regular large wheel of a unicycle, but that wheel is actually made up of several small wheels in a series, which can rotate independently, meaning that the device can go forward, backward, side-to-side and diagonally, all being controlled with a simple lean. Honda credits its ASIMO research for this multi-directional capability, though we're not sure we see it -- ASIMO is biped, after all -- but far be it from us to discredit an excuse to keep up the good work on the ASIMO front. Right now the "experimental model" of the U3-X gets a single hour of battery and weighs under 22 pounds, with a seat and foot rests that fold into the device for extra portability. No word of course on when the thing might make it to market, but Honda plans to show it off next month at the Tokyo Motor Show. A devastatingly short video of the U3-X in action is after the break.

Wouldn't be caught dead on an honest-to-goodness Segway? How's about this creature? The Legway, an appropriately dubbed steampunk'd Segway, ditches the electric motor in favor of Fred Flintstone-esque motoring techniques, and it also relies almost entirely on recycled materials. The crazy part? Its creator even took the time to hand craft a step-by-step guide to building your own, which undoubtedly foreshadows the real human transporter revolution. Unfortunately, there seems to be no word on whether this thing will also reverse in unstoppable fashion when you least expect it, so stay sharp out there. Vid's after the break, and it's absolutely hilarious.

Well, the base might be ripped right from the Showbots, but Exmovere Holdings doesn't seem to be totally kidding about its "Chariot" wearable transportation device. There's a new video up that demonstrates its use, with a character akin to the Summer Heights High guy at the helm ("I'm a little early," "He's stuck in traffic, you know. I just took my own way here, so I had no problems..."). If you can get past his slightly annoying implementation of the Chariot, it's not hard to see the benefits of a device like this over a wheelchair -- if it pans out, that is. Our theory is that Exmovere is using this gaudy Showbots platform as a jumping off point, adding in accessibility features, working on additional functionality (like sitting) and hopefully tweaking the looks before it goes to market. Hit up the read link for the video.

Against all odds, GM and Segway let us inside their precious P.U.M.A. prototype, and we went for a quick jaunt down 18th St. We couldn't drive it, unfortunately, but there was plenty of action to be had from the passenger side. Starting from a rest on four wheels -- the main powered wheels and the front two "safety" wheels; we never touched the back two to the ground -- the contraption shoves itself up onto two wheels quite gracefully, with the passenger compartment moving slightly independently from the wheelbase and floor. It was a bit odd, but not at all unpleasant, and we were soon zipping down the road. Since the P.U.M.A. is self-balancing, we felt way less force when accelerating and decelerating than we would in a car, since our body was being "leaned" into it instead of pulled along. Turning on a dime is quite fun as well, and we could see this thing making itself quite at home on city streets. While it remains to be seen if GM and Segway can commercialize this in time, and for the right price, we're fairly enamored -- at least it's something different, and it's already twice as interesting as Segway ever managed to be.

We just lived, breathed and experienced GM and Segway's joint press conference, where they "unveiled" the P.U.M.A. one more time for effect. Larry Burns and Jim Norrod from GM and Segway, respectively, talked up what they each brought to the table, and described the vehicle's inception as a partnership.

Segway obviously brought the two-wheel mojo, and seems responsible for most of what's being shown at the moment. As opposed to the Segway's tilt-and-cringe system of navigation, the P.U.M.A. has a more regular steering wheel, but while they're currently demonstrating it with Segway-style acceleration, they plan on swapping that for "Nintendo-style" buttons behind the wheel for acceleration and braking. For GM's part, they plan to integrate its "connected vehicles" technologies to improve safety and efficiency -- and we might not see P.U.M.A. on the road until they can pull it off. The car will not only communicate with other cars and with GPS, but will sense and stop for pedestrians. They plan to show a connected version that will be available for test drives by Real Actual Humans this coming fall, and then next year will come the scariest of all unveilings: GM styling. Right now this is just a chassis, GM plans on slapping on all sorts of "fashionable" candy shells, and if the incredibly unrealistic and "futuristic" renders we saw are any indication (see the gallery below), we'd really rather do without.

The biggest obstacle to commercialization, however, is the lack of infrastructure: P.U.M.A. in its current incarnation is designed for for bike lanes, and the first cities to get it will be ones with existing, comprehensive bike lanes -- not as much of an obstacle in Europe, but quite the stretch for most American cities. Still, the mathematics are quite alluring, with a 35 mile range at 35 mph for a 35 cent charge -- even us mouth-breathing Statesiders can understand that.

Update: We added a video after the break, along with a couple outdoor shots in the gallery. The thing really does look and operate like a two-person, sit-down, Woz-free Segway. You have been warned.

GM and Segway's joint venture is probably best described as a rickshaw without all the charm. The self-balancing Personal Urban Mobility and Accessibility Project (P.U.M.A.) can reach top speeds of 35 MPH, has a lithium battery that lasts up to 35 miles with a single charge, and features vehicle-to-vehicle (V2V) communication for potentially reducing the number of accidents. No word on when or if this'll actually go into production but it's expected to be priced at just 25% that of a regular automobile. Hit up the read link for more pics, including a concept model that's just a teensy bit more reasonable. We'll be at the launch event tomorrow to see it for ourselves and make sure it's not all some bizarre dream.

If the Segway's current movement mechanism and cast of characters astride them wasn't keeping you up at night, the Cajun Crawler should seal the deal. Based on the work of kinetic sculptor Theo Jansen, the Cajun Crawler holds up a Segway-style platform with a scary collection of steampunk-like mechanical legs, which can scurry across a floor with surprising agility. The project was built by a team of folks at the University of Louisiana, who do not know the meaning of fear. Video is after the break.

It's something that any hard-nosed entrepreneur likely deals with when their invention / startup is on the edge of fail: should they simply throw in the towel, or forge ahead like no one's looking? The father of the Segway, Dean Kamen, is also wrestling with that question. In a recent interview, he stated: "You end up lying there saying, 'I'm not stopping. It would be an act of shallow cowardice. Or you decide to quit and you say, 'This is one of those ideas that just isn't going to work.' " He also noted that "it's not nearly as glamorous as people think to keep working on something and to keep hitting roadblocks and to keep going." On one hand, we could definitely see the rug being pulled from the two-wheeled transporter that never revolutionized public movement, but considering all the days in which it has lifted our spirits, do we really want it to?

Four wheels, custom rims, a fold-out DVD player, and a metallic paint job? Eat your heart out, Woz. Couple more after the break.

Did you like the idea of Ben Smither's single-wheeled, self-balancing scooter but wished the thing looked a little less... utilitarian? Check out John Dingley's one wheeled self-balancing skateboard project, aka "The No Snowboard," aka "The Hot Wheel." It was inspired by Smither's earlier creation and likewise relies on a single go cart racing slick in the center spun by a (slightly more powerful) 420W electric motor, but adds a lovely wooden surface and racing decals to the top, improving the look immensely. The rider leans in either direction to get the thing going (as demonstrated in motion below) and the slight curvature of the tire allows for turning just like you would with a normal skateboard. Right now maximum speed is a somewhat pedestrian 7 mph, but Dingley estimates that a Segway-matching 12 mph is possible with better gearing. We can't wait for the inevitable self-balancing scooter racing series.

What could possibly provide us more joy and mirth than a Segway? How about a Segway-inspired bot that fails spectacularly on a consistent basis? The tech in play here is quite simple, and the fact it can stand as long as it does being that top heavy is actually pretty surprising. The best news? Hit the read link for a guide to making your very own fail bot at home. It's fun for the whole family.

Our Deutsch is a little rusty, but Spiegel's got a hard-hitting, um, sounding story on Segway safety -- specifically regarding what happens when one hits a stationary object or falls off of one while riding it at full speed. Hey der Spiegel, why don't you try the same test with one of those bicycle contraptions we hear Europeans are so in love with? We have a feeling you might be slightly more horrified by the results.
