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."

      Seriously, though. Why would you use a Segway instead of, say, a four-wheel RC car?

      Because it is easier to model and control the segway. Think of it this way: You have a robot based on the segway, and one based on a 4-wheeled rc car. They are both pointing north. Consider how much easier it is to get the segway to point south, while maintaining the same position (Just changing orientation). If the RC car had differential steering (like a tank), then yeah, you don't need a segway.

      If you look at most lab grade wheeled/tracked robots, most all have differential steering. What the segway based version has going for it is that it maintaines a constant vertial orientation--it is a stabilized inverted pendulum: It's always "righted" or "pointing up." (Well, in cases where the wheels are at the same Z, anyway.)

      From the computer vision point of view, this is really nice to have. If you had a camera mounted on any other type of robot, and wanted to visually point "out" at something, you'd need to measure the changing orintation of the robot as it clambered over objects or moved up and down hills. The most common way of doing this is to put a gyro or other angular rate sensor or inertial reference unit on the robot base, and then feed-forward the dynamics of the base to a pan/tilt type mechanism to move the camera. (All the extra work & crap required to do this would offset the cost of buying the segway, by the way...) Alternatively, you could close a loop around a video tracker to adjust pan/tilt, but that's been done before, too.

      What would be really cool would be to stabilize the segway in 2 angular degrees of freedom. Then, a vision system could be decoupled--easily-- from the robot platform in roll & pitch.(An additional single axis rotation stage could offload any yaw.)

    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.

    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.

      It is an inverted pendulum. Of course it has to move its wheels to maintain balance. Unless its wheels are constrained.

      I disagree it being a control nightmare. Have you ever seen an inverted pendulum? Find a video on the web. They're easy to control, and well studied. (Missiles, rockets, inverted pendulum, cart and pendulum, etc.)

      I might be wrong, but isn't the segway stable even when off-like those blow-up punching bags? I've only seen it in videos and on Leno, and they were upright while parked. Kickstand maybe?

      The RC car modeling nightmare isn't so much in the dynamics of the platform as it is in finding a control method to orient it in the way you want at the position where you want it. Imagine how big a pain in the ass it is to get an RC car to turn around 180deg, ending up in its original location.

      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

      Well, my usual approach is to use a 2-axis gyro for low frequencies and MHD rate sensors for high frequencies. Blending the output yields a nice 2-axis broadband angular rate sensor. Very high accuracy. Not cheap.

      You're right though. I would never use a segway in CV when a regular robot with a stabilized gimbal or IMU could give me the same thing with fewer complications.

      And yes, balancing on two wheels is cool.

      It's worse than other platforms in many ways, including the ones you discuss.

      Practically speaking, I wholeheartedly agree. But like you said, It's cool, and that gets attention (on Slashdot) and maybe more $$$. One thing i've learned in school/at work: It doesn't have to be the best solution to be publishable or to convince customers to throw more money your way. Wierd ideas get money. Just look at the weirdness that DARPA funds.

      We're on the same page, but I'm thinking of it as a proposal generation type of toy, not as a practical solution. As a computer vision person, let me tell you that just slapping a camera on the front of a segway and compiling the simplest possible obstacle avoidance program will yield a thesis, many many conference papers, a few journal papers, and probably more application specific proposals for additional funding. That's just the academic way.

      Besides, if they bought it for research, they would have had to have a good reason other than it being cool. Know what it is?
