Jason,
     Looks like the question is answered. I hope you can demo it at the April meeting. It is a little expensive for me to be a pioneer, but I sure would like one.
Regards,
Doug P.

what issue? the laser can be looked at all you want as long as you don't magnify it. It is a class I if you go by old school rating and is rated a 1M if you go by new school ratings.

  Jason,
       I have wondered about this also. I agree that a 4” height would reduce risk, but I could see a situation of a kid lying on the ground to look at the robots. I know the vacuuming robot that has the laser sensor (displayed by Paul last year) rotates which minimizes the duration of continuous exposure, but the manufacturer may limit power or use some other method to pass government safety regulations.  I’m just curious. Is this issued addressed in the forums or by the seller?

  Regards,
  Doug P.

    Hope this does not cause a problem, but what power laser are we talking about? I'm uncomfortable with a class2 or higher laser potentially smacking someone in the eyes. A handheld laser you use for measuring room distance or the distance on a golf course has a human operator who is potentially wise enough not to shine it at people, but a robot scanning with a laser probably doesn't have the discretion so I feel compelled to mention that there is a potential hazard and precautions should be taken to ensure everyone's safety.

    Yeah my long run plans are the throw this on a dynamixel and scan with it or something like that so i can do some more accurate slam mapping.

      Not sure if I responded previously but I am interested in your findings with this device. 

      I looked at it earlier, and we discussed it on the list a bit, for my competition robots. I came close to ordering one but held off because the beam width is narrow, as one would expect with a laser, so my rovers would need a scanning mechanism. I did not want to purse that complexity at the time.

          has a range .5m to 9m
          cost is 100 bucks
          or make your own starting with a 15 dollar kit. 
          Shipping is not cheap DHL only.
          I already have one on order. Will demo it once it gets in and i get some code working on it.
