Sonar or Optical
« on: June 24, 2009, 04:02:09 PM »
Simple question. Which is a more reliable detector. Which one has a higher and less error prone cycle rate?

I want to use in three situations.

1) Wall or object detection (medium distance), rotating on top of robot.
2) Drop off dector (short distance) o see if I'm falling off a mountain or my staircase.
3) Far object predictability (long distance) to make measurements of objects far away, used in conjunction with the medium range to plan a better path.

Any help appreciated.

Thanks

need to know more details about what your trying to do long and short isnt cutting it cause long could be a foot or it could be 10 feet... or it couble be a float point variable....
just about anything you get beside the laser range detectors which cost in the thousands of dollars are going to have there disadvantages....
my english teacher once said, "dont talk about what you dont know in public...."

so I replied the truth, " Exactly why I dont ever talk about English."
