Linux-Controlled Segway Robot
ptorrone writes "It was just a matter of time until the Segway technology would be used as a robotics platform. University of Southern California Robotics Lab's Segway RMP (Robotic Mobility Platform) has a lot of great information if you're looking to convert a Segway to a robot. On the site there are videos as well as instruction on how to build your own." Update: 07/13 21:30 GMT by T : Dr. Andrew Howard writes with an important clarification about the project: "This is *not* a standard Segway HT that we have
converted to robotics applications. Rather, this is a customized, limited
production unit that has been specially modified by the manufacturer.
The web-site does *not* show how to convert an existing Segway HT into a
robotic platform."

I particularly enjoy the shot of it falling over.
Seriously, though. Why would you use a Segway instead of, say, a four-wheel RC car?
Like this one?
....it's ten times cheaper than the RC??
see, why you'll use a Linux segway, that's the real question....

Can this thing mow my grass? I wonder if the segways have enough torq to push a lawn mower.
Anybody that has know know the answer to this? If they do, you could make a little device that it goes and attaches to which fits a lawn mower onto the segway. Add some voice recognition, and you're one "Segway, please mow my lawn." away from enjoying a lime and tonic while your grass gets cut.

I better add another Segway to my Amazon.com wishlist: that way I can have one to drive around myself, and I can train my linux-robot-segway (I'll name him Frank) to follow me around, and guard my segway when I leave it outside as I shop. Unless I can take it into the store, in which case I'll just have to make Frank into a self-propelled grocery cart.
Excellent!
Yeesh. Build your own balancing bot and have at it. This isn't even a hack worthy of mention - it's more like a Segway sales pitch targeted at overbudgeted academics with too much time on their hands.

..since the only really impressive thing about the segway is the way it interacts with human balance. If you take the human out of the equation, the problem is just so much simpler. True, balance in a robot is a challenge in itself, but I just wouldn't start with a system whose design centers around maintaining balance with a human rider (at least if money was a factor), since you have to throw away so much of their technology.
Have a how-to on turning a Segway into something that doesn't suck.
If this isn't simply a troll, try enabling DMA on your drives. Though, since you've state that you've been waiting for 20 minutes, I'm inclined to believe that you've made this scenario up and are merely trying to hook some rabid 10-year-old linux fan.
/dev/"
DMA being disabled on any operating system means a significant amount of CPU time gets spent on reading and writing to disk. You can either enable it in your kernel config (I can't see why your distro provider wouldn't have done this in the first place), or you can use hdparm in this manner, "hdparm -d1
A 17 MB file should take seconds unless significant additional processing of file data is necessary regardless of operating system.
To cite a recent sign of the lack of robustness in the windows operating system (or cygwin) I attempted to back up a linux machine to a windows machine using cygwin and rsync. With about 700,000 files to consider the windows machine took literally days to get through simply dealing with the list of files before even transferring. Attempting the same, later, with a linux host (after augmenting disk space to allow for the process), considering the list of files took about 2-3 minutes, and the transfer took several hours (20 GB, compression enabled).
I used Visual Basic .NET to build MY Segway robot. These people who use Linux are nuts!

Please, humour me...
Is the fact that this thing runs on Linux so important that it should lead the headline? Really, is the story about the robot or the OS it uses?
Would there be a similar headline if it used XP or OSX?
I'm just wonderin'.

I think it would be very cool to use this as a platform for a robot battle. It could provide something unique over the plethora of wedge-bots that everyone seems to use now. Call it the weeble-wobble-bot. Not only could you drive it around, but you could add in intelligence to react to events (though I'm not sure if it's legal in the games). The price is suprisingly reasonable if you are aware of what a lot of the competition bots cost.

These files are encoded in a properitry formant. Now I can't watch it. And don't mention mplayer, as I have gcc 2.96 installed so i can't use it and don't mention xine, as you have to violate the DMCA to install it.
Whenever there's a story about a Segway on /., some troll asks "Yeah, but does it run Linux?" Well, buck up, buttercup, the answer is YES!

A typical 200 pound adult riding a segway is centered directly over the axle and actively balancing to stay there (so I understand, I've never ridden one). On the other hand, a typical lawnmower is located several feet away from the same axis of rotation. Big difference. Will there be enough weight on a typical segway to provide enough torque to actually accomplish the horizontal push you need? Easily fixed with sandbags or redesigning to put the blades directly under the wheels I suppose, though.
I give an off-hand estimate that my lawn mower weighs 75 to 125 pounds. It is self-propelled, but the self-propelling gear ratio is not enough to move it by itself: you still have to push. Automatic mowers don't really need self-balancing like the Segways have, but kicking back and watching the robots attack your low grass is a savory idea.

You are none too ready to point out that you are travelling with an iBook. Hurrah for you! But if this means you can't figure out how to play a DivX, that is nobody's fault but your own. Whiny bitch.
On cygwin all file operations have to go through cygwin.dll, and this tends to slow things down a lot. Maybe you should blame cygwin instead.
I can't agree or disagree with this because I don't use Linux often, but not being able to avoid crude jokes and other negative comments about Windows, Microsoft or Bill Gates does get annoying. I don't always disagree with the comments, but several of them are incredibly immature, and I often find myself rolling my eyes and wondering why 'whoever posted that' is a Slashdotter. But personally, I like Windows. Okay, I'll admit that 98, ME and 2000 could be very problematic at times, but XP is great as far as I'm concered. I'm not saying it's better than Linux, because I don't think it is, but it's a good, easy to use OS. Last time I posted something like this, I was flamed, so we'll see what happens this time. I guess it's the price I pay for surfing a great site like this - there's really no better source for tech news, but it's not perfect.
Mplayer also works very well with AVI files. It gives you a little more control over the playback, but doesn't play VOBs or OGM files, so I keep both on-hand and use whichever works best.

You're missing the most interesting fact about the segway, in that the rider doesn't activly balance, the segway does. The trick to riding the things is to stop trying to balance.
I always thought the segway looked like a push mower, and was picturing a design with the blades around the body. It'd be much cooler to just strap a segway to a regular mower though. For both designs the auto balancing isn't needed.

Or a remote-controlled mower. I thought of fully automating my mower, but dealing with the safety issues of an unattended 5hp motor spinning a sharp blade isn't worth the effort for something I do about once every 10 days. However, by radio control, safety is easier to deal with and it goes from being an annoying, sweaty chore to an entertaining one. The only problem I foresee is steering -- at the end of a strip, I turn my mower around by pivoting it on its rear wheels. To emulate this, I'd need skid-steering or other turn-in-place method.
What I really need is to find a cheap $30 mower I can work on so my regular one isn't out of commission while (if
While they aren't a useful and sensible mode of transport (yet), they are very good fun. Jeremy Clarkson crashed one, and swore (quite entertaining), while shortarse Hammond at the end improvised the Segway equivalent of the sand dance.

well, since it doesn't seem like an "off the shelf" segway will work with what they're doing. i'm going to make my own, most like with the combination of 2 rc devices one to turn the handle the other one to shift weight forward and back on the platform, making in autonomous will be tough, but that will be a fun puzzle once i can rc control it.
i'll post it up on the segway journal in the articles section, when i start.

Considering this company also makes those electric scooter-style wheelchairs (which may even cost more), I think Segway's goal is to increase obesity in the world so they can sell more of these darned things.
If you want to cruise to work and not look like a complete loser, try a skateboard, one of those scooters, or a variety of human-powered modes of slow transportation. At the very least, go on a televator strapped to a snowboard. More surface area on a televator means more traction, which means a higher top-speed. No shoes to catch, plus a stable base means no transition problems. And, when you are on a snowboard, falling down is cool anyway.

... my brother is the DARPA project manager for the Segway stuff. In fact, it was his idea to explore the uses of Segway as an autonomous robot. He bought a couple dozen and spread them around to various universities, etc.

Linux powered segway robot
Doesn't that describe all segway owners ?
The reason to use a segway is for the cool factor. Period. It's worse than other platforms in many ways, including the ones you discuss.
As you note, it's better to use an RC tank than a car (or the higher-grade equivalent). Compared to a standard differential drive though, the Segway looses big. Consider having the robot just sit there, stationary. The segway doesn't. It must move it's wheels to maintain balance; a modeling nightmare. In any case, if you want a precise match between model and movement, with maximum flexibility, but aren't dealing with rough terrain, you should use some form of holonome. If you are dealing with rough terrain, you're not going to get precise modeling in any case.
As far as a stable platform for vision/sensors: The typical solution (e.g. a compass, two levels and some cheap servos) is going to cost a few hundred bucks if you want to do it really well. Nowhere close to offsetting the segway. And the segway is only getting you one axis; you still need the usual solution for the others. And it's not doing that axis very well. The Segway probably has some wobble, and needs to lean forward when moving in any case.
This is being done because balancing on two wheels is cool.
