OpenSimpleLidar
Open Hardware scanning laser rangefinder.
Its parameters:
- 5 scans/second
- 180 measurements per rotation (2 deg anglular resolution)
- Maximum distance - 4 m
- Measured accuracy ~3-5 cm at 3 m (depends upon the color of reflecting surface).
This device is really cheap - its components cost less than $30.
See "TotalBOM" with price calculations.
Now I'm updating the documentation for this LIDAR.
Some of it I'm writing to the project wiki: https://github.com/iliasam/OpenSimpleLidar/wiki
Please take the simple survey about assembling instructions
Utility for displaying "radar" scans from the working Lidar:
Example of Hector SLAM working with this Lidar:
This Lidar is using triangulation method for measuring distance to objects. It can be shown by this picture:
Some modeled pictures of the assembled Lidar can be found here: https://github.com/iliasam/OpenSimpleLidar/tree/master/Misc/Pictures/

If you need LIDAR with increased speed and range, see this project: https://github.com/iliasam/OpenTOFLidar
Please leave your feedback if you will be able to build this Lidar - I need more feedback about assembing instructions.
