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!

    If seen people put an ultrasonic sensor on a serve. By moving the servo you can "scan" the surroundings. It is however a bit slow.

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.

  • Wait so would you suggest just using the infrared distance sensors then?
