Hi guys,

does anyone know of a relatively cheap sensor solution for 2D mapping? don't need it to be (laser) accurate. just good enough to build a 2D map for some basic indoor navigation job.

Sonar, IR, anything that might do the job.

UPDATE: i also found LiDAR-Lite i guess its fairly new to the marker. it is also very cheap but it should be modified to cover 360 degree around it. anyone tried it before?

Thanks for the ideas n answers.

Here's a Poor man lidar, that could be used for mapping. It uses a sharp IR sensor and a servo.

The xv-11 laser is a fairly cheap setup for under $100 on eBay.

hello! have you ever tried a PML before? i thought i'd eliminate the moving parts and build an ir_ring instead, any ideas?

I've done both suggestion second is better. I was never able to get a good map with the IR moving on a servo and my robot moving. Probably could have built a decent map if I had stitch several static maps together.

by second, you mean IR ring or xv-11?

xv-11. I haven't done the IR ring but it should work. Any particular reason for no moving parts?

just for eliminating moving parts (risk of mechanic failure) and also i wanna put a cover over the robot, panning IR will need a wide opening in the robot's cover. but I'm thinking a ring may have some overlapping and blind spot problems.

I like the idea, I'll have to follow up with you to see how well it works out. You could use a couple of bumpers in the front to protect against blind spots.

yea sure, lets see what i end up buying and we'll see how it works out. Lidar is tempting though lol do you happen to know of a working exploration package? I'm stuck.

Sorry I don't.

I do not know if it will be cheap enough.

Hi! its looks the same as xv_11 lidar, have you tried it? are these two different products?

I have tried the rplidar with hector slam it works great!

RPLidar works great with GMapping too for me

An Xtion from Asus is also enough for indoor navigation. A drawback would be its limited field of view. An example of using it with a turtlebot for navigation can be found here.

Hi, i was thinking more about an IR or a cheap lidar solution, and primarily wanted to couple it with an Exploration pkg, which looks like "Exploration" is not easy to find either! any idea's for that part?

In the field of robotics, a Xtion or a Kinect IS a "cheap" sensor !!!

Tera Ranger One could be another choice. The ROS package is given here on the github.
