Military Robots to Gain Advanced Sight 71

coondoggie brings us a NetworkWorld report discussing iRobot's plans to include Laser Radar technology in their military robots. Quoting: "Specifically the robot-maker is licensing Advanced Scientific Concepts' 3-D flash Ladar which uses laser beams to scan and process targets. The system has the ability to create a virtual 3D picture of an entire area. IRobot ... believes the technology will provide new navigation and mapping capabilities for future generations of robots and unmanned ground vehicles and pave the way for autonomous vehicles to lead convoys into dangerous territory, search contaminated buildings for casualties, or enable bomb squads to safely investigate suspicious objects."

    Maybe iRobot will put this into their Roombas and allow us to get rid of some of the IR gates that they use now. I don't know how many times I've stepped on one of them after they migrate to the center of the room in the dead of night.

    Also, does anyone else find it disturbing that they also make military robots?

      Yeah, one day soon your Roomba will get drafted and you'll die a slow agonising death, suffocated by a sea of dust bunnies.

      Don't laugh. It could happen.
      • I was just thinking; That the market that would buy such a war device, would maybe be 1000 people? But if iRobot's engineers could work on a self cleaning,(dust bunny dumper), that could climb stairs, and vacuum in the corners, THAT market would be about 5 Billion people.
        • Yeah, but those 1000 people control the purse strings of a nation with a $13.7 trillion economy. Think of it as iRobot preferring to sell Ferraris rather than a bunch of Yugos. Compared to military contracts, we're peanuts.

      Let's see... The microwave oven was originally developed by Raytheon with the Amana unit eventually getting spun off. Boeing makes lots of military airplanes and systems besides their commercial jets. General Electric makes a variety of military stuff (e.g., jet engines, radar, etc.) as well as all of their consumer stuff. United Technologies makes jet engines for both military and commercial aviation. Back when I worked at TRW the company had both the Defense Systems Group I worked for as well as TRW Credit Data.

      These are just a few businesses that have both military and civilian products. Better be careful or your Roomba will form a junta with your microwave oven and toaster and take over your house.

      Cheers,
      Dave

    I'd figure there also are a lot of civil applications for this technology? Contracting, driver-less cars, game-development? Oh, the fun we'd have.

      Laser systems have been in use for civil applications for a long time. In fact, the ubiquitous SICK scanners used in robotics are repurposed from industrial equipment safety (high end light gates).

      This story is more about how iRobot is going to field a commercial system that uses better laser sensors. Not that big of a deal really.

    This is a big step forward. I know this technology. Back in 2004, when we were putting our DARPA Grand Challenge vehicle together, I went down to Advanced Scientific Concepts [advancedsc...ncepts.com] in Santa Barbara to see the thing. Back then, they had a prototype that worked, but it was on an optical bench (one of those big plates with screw holes to which you attach optical components), nowhere near ready to go on a vehicle. It was just too early. We had to go with SICK rotating-mirror line scanners, like everybody else. But I was convinced it was the right direction to go, and I dragged a venture capitalist who had some underperforming photonics companies down there to see the thing. He didn't want to fund them, because they were too far from a consumer product; the near term market was DoD-only.

    ASC kept working, and by 2006 they had working portable prototypes. By 2007, you could buy a LIDAR about the size of a large-format camera for about $100,000. Now they've downsized it further.

    Unlike the laser scanners with spinning mirrors or sensors, which is what everyone else uses, this technology has no moving parts. The system has two main components - a pulse laser with diffusing optics, and a detection and timing IC with one LIDAR receiver per pixel. Neither of these is inherently expensive in quantity. It may take a while to get this down to webcam prices, but $1000 is a reasonable near-term target.

    It's amazing that this can be done in an eye-safe way, since this approach is subject to the radar equation - returned power decreases as the fourth power of the distance. But the detectors can be made good enough. Some of their more sensitive detectors use a photomultiplier tube technology, like a night vision system. Night vision systems use a photoelectric detector plate - when a photon hits it, an electron pops out. Electric fields are used to accelerate the electron, which then hits one of the electron detectors on a specially designed IC. Photomultipliers have been around for decades, and can detect single photons. The neat thing about the photoelectric effect is that it's at the atomic level, and happens in picoseconds. So it can be used as a light amplifier for a time-of-flight LIDAR.

    The current generation of compact sensor is 128x128 pixels at 30Hz. The sensors are currently smaller than the lasers, but for smaller robots where you need only 10m of range or so, a smaller laser can be used.

    This is the sensor that will make automatic driving commercially feasible.

      I'd have to question your "returned power decreases as the fourth power of the distance" claim.

      This is true with radar, yes, because your radar beam increases spatially in two dimensions on the way to the target, ping at a point source, then diffuses again in two dimensions from there.

      With lidar, you have a coherent focused beam on the way there. Lasers are generally considered to not lose any significant power over distance in a vacuum. You still have the ping, or reflection event, at which point you'll no

        Not with a flash LIDAR. There's one big broad flash spread by a beam spreader, not a mechanically scanned narrow beam. I'm amazed that it works over substantial distances. There aren't that many photons coming back per pixel. They don't spread the beam very wide; 1 to 9 degrees is typical for the longer ranged units. At shorter ranges, a

      I, too, worked on the grand/urban challenges. At one of the post-competition conferences Ibeo (owned by SICK) claimed that they would be able to produce their 4-beam LIDARS (with builtin target tracking that works semi-OK in highway-type scenarios) for $300 by two years time. Of course the Ibeo ALASCAs and such still have moving parts and work in only specific situations, but they're getting pretty good.. or at least better.

      Having said that, a *huge* problem with LIDARS (like RADARs or any other active sensors) in a military environment is that carrying a LIDAR is the same as carrying a homing device for any basic IR-targeted bomb/missile.

      "Where's that convoy, Sam?"
      "Put on your IR goggles and look for the huge disco light in the middle of the desert, Bob!"
      "Wow, Sam, thats WICKED!"

      So I'm not sure how they're addressing that, or if they're hoping for an application niche that doesn't deal with being shot at altogether.
      • by Animats ( 122034 )

        Yes, actives are just too visible. It doesn't matter much in urban environments, though; it's not like you can hide an Army truck driving through a town.

        IF you're looking 250 meters your flash LIDAR would get a return within 1.7 microseconds. If you create a 1.7 microsecond flash at a frequency of 10Hz you're only emitting 0.0017% of the time.

        Let's say the light you pulse is as bright as a 100kW bulb (i.e. a thousand 100W bulbs). With that du
  • Isn't it called LiDAR ?
  • Does anyone have some information regarding, how fast such sensor can be at the moment? Speaking in terms of scans per second. I used to work on a project dealing with a 3d laser scanner (although not in a military context ^^) and that one wasn't even close to being fast enough to sense and destroy a target before being blasted to pieces.

    I don't get the news here. This is the standard sensor for all robots, and they've been using "lidar" for years.
