Chinese heli UAV, can;

I don't know what they are saying, but this is pretty interesting to look at.

  • Ok, my Chinese isn't that great, and I have little to no grasp of technical terminology. I think it's some sort of marketing/press-release material.

    The talsk about their flexible L18C twin rotor UAV platform, it mentions a little about how they've had input from research, and how they have a highly trained/skilled maintenance and operation crew. They highlighting the benefits of a helicopter-type UAV (no need for runway, controllable from ground station, can be used in dangerous situations instead of risking manned aircraft, and serves a flexible air-borne platform for applications both military and civillian, blah blah).

    I think they're saying the thing has accelerometers, gyro, a 5Hz GPS module, and at least a couple of other sensors I didn't quit catch, and something about an awesome control system that allows high-performance flight control down to 0.1 degrees? The 246cc power plant runs for 1 hour with standard fuel tank, 2.5 hours on extended fuel tank, dimensions 3630mm x 1280mm, weighs 100kg and can carry a payload of 30kg. The advanced control systems make controlling the UAV very easy

    The second part says something about the autonomous Rmax system being designed for remote operation or situations requiring complex autonomous flight, and is built on the L18C UAV platform. They mention it being capable of autonomously navigating waypoints set by a controller; and that "the autonomous Rmax's autonomous flight controller and the ground control guidance system are the heart of the technology, and allows the craft to accomplish all sorts of complex maneuvers, many of which are impossible on manned flight systems" (managed to understand that part pretty well). Flight speed of over 72km/h.

    Standard payload includes a stabilised 3-in-one vision system - laser rangefinder, infra-red and visible-light cameras, with 360 degrees by 90 degrees freedom. It debued in December 2003 in Beijing, generating a huge amount of interest, and there is hope that novel autonomous UAVs such as this one will soon become part of the every day lives of everyone in China (?).

    All in all, it doesn't give away anything particularly interesting other than a few key specs that I hope I've mostly covered, they don't really talk much the awesome auto-tracking antennas you can see in the video. Maybe someone with a better grasp of the language than I can shed some light on this?
  • I believe it was the sale of some Rmax's to China that caused all the fuss at Yamaha and effectively prevented further exports.
  • I heard they are import restricted to 3 per year here in the U.S of A. Good Luck! :D
  • 100KM
    full tower ? thats exactly right


  • I just like the auto tracking dishes.

    Why do they need such a big payload? I can see it for some sensors and if you want to haul a full tower computer around that can play crysis.
  • I can make an R-Max look Norwegian.
  • 3D Robotics
    I'm not sure what they're saying either, but those are the standard Yamaha Rmax helis that all the big guys (NASA, universities) use for autonomy. Crazy expensive, but they can lift a huge payload. Originally designed for RC crop spraying in Japan. A couple Yamaha execs went to jail for selling the autonomous versions abroad--they must have done it the right way this time.

    Pretty fancy antennas, however!
