Range scanner comparison?
I'm new to the forum, and fairly new to robotics. I'm currently considering working on a research project involving multiple robots mapping an environment (something simple, like a wooden maze) together. For the mapping I would need a fairly reliable range sensor. I would very, very much appreciate some advice from seasoned robotics veterans such as many of you on this site!
- Do you know of any reasonably priced laser range scanners? (Preferably below $500, not sure if that's possible at all!)
- Do other range measuring sensors provide reasonably good alternatives? I've noticed that many hobby robots use ultrasonic or infrared range finders but most seem to measure distance to obstacles only directly in front of the robot. I would hope to get distance measurements for a whole range of points in front (and to the side) of the robot.
Any advice, experience or pointers to tutorials etc. would be brilliant!
Thanks a lot,
