If there is bringt sunlight, Does your system still work well?
to be honest, i still haven't finished this robot's motor controllers (any day now) so the sensor still hasn't been mounted on the robot or been outside.
but yes, i'd imagine bright sunlight would decrease the effectiveness quite a lot.
i think you would get 10 meters range as long as you use a bright enough laser and use a high quality web cam though.
(a high quality web cam would start adding to the cost though....)
your solution seems cubersome.
if you have a processor with a USB host port capable of accessing a webcam on board then the individual components are quite small but you do need to mount them a distance appart.
(the further appart, the greater the accuracy.)
if you don't have a processor with a USB host port on board then you are going to need one, making it very cubersome and quite expensive...
good luck and let us know if you find anything better.
