Segway-Based Robot Opens Doors 158

Posted by simoniker from the only-when-turned-on dept.
Roland Piquepaille writes "In this short article, Technology Review tells us that Massachusetts Institute of Technology (MIT) researchers have built a new robot, named Cardea, which is able to push open doors and has the bottom half of a Segway scooter. Cardea will be five feet tall with a torso, three arms, a variety of sensors, and a human-like head with expressive features and vision, and mounted on a Segway base. More details and references are contained in this review which also includes several pictures. For even more details, go to the Cardea Project homepage."

    The primary problem with two-wheeled robots so far has been balance. This project solves that, not only with the Segway platform, but with a kickstand that extends when batteries cut out.

    How long do the batteries last, anyway? It's not much good if they run out in, say, five minutes.

    A recent article in SciAm described small robots that can be thrown through windows and will run around and map the area. I wonder if this robot could do the same? But what if it runs into stairs?

    Just some thoughts.

      This robot's design is actually pretty cool. If you go to this site [mit.edu] you will see a bunch of really cool pictures, and even a video about the Cardea. It has three arms, which may seem awkward at first, but actually it is a pretty ingenius design. The "extra" arm isn't really its own arm, it is more of an extension of the left arm that allows the Cardea to open doors and hold objects better.

    Just a dumb question, but if I remember correctly the regular segway works by having the operator balance it somewhat like a bicycle, hence the small learning curve to operate the Segway.

    So my question is, does this robot have some sort of balancing algorithm programmed into it so it doesn't fall flat on its face?

      It works with a gyroscope in the base that tilts it back and forth so the center of gravity remains in the center.

      That's why you can lean forward on a Segway and still stay up.

    • Just a dumb question, but if I remember correctly the regular segway works by having the operator balance it somewhat like a bicycle, hence the small learning curve to operate the Segway.

      Nope, the segway works by using a gyroscope to detect balance, then driving the wheels forwards or backwards to keep balance. (Think; those guys in the circus who have those long poles with plates/etc on their heads and run backwards and forwards to keep the poles balanced).

    The base for that robot is an official development platform called, I think, the Segway RMP, not just "the bottom half of a Segway." My college has one, too. It acts a bit differently from a regular Segway and can reasonably easily be remote controlled, balancing itself with up to 250 pounds on it. At the moment, it seems they've stuck a robot torso on top of the RMP. Not to say that's not a reasonable accomplishment in itself. I'm an undergrad research assistant in a robotics lab, and real-world application can be extremely frustrating.
