user6388: I'm trying to develop something that requires accurate distance measurement of objects around the center of the contraption. However, I cannot find any way to achieve this other than using a bunch of infrared distance sensors. Really, I'm looking for something that costs at most $200 and is compatible either with arduino, PC, or raspberry pi.
This may not be the place for this, if not, please inform me.
Thanks in advance!

user368: What you're looking for is called lidar - but it's not cheap. RPLIDAR is the current price leader for non-hacky solutions, and I haven't seen it for much less than $400 anywhere.
