Hello, I am just a noob in ROS and I need your help. LIDARS are very costly in India and they are mostly not available so is the case for a Microsoft Kinect, it is available but costly, so can the IR range finder from SHARP (SHARP IR RANGE FINDER GP2YOA21YKOF) with my RPI 2 be used? Heres the link...

Thanks for ur help in advance, im very sorry to disturb u asking such stupid questions but it be great if u could help me.

Best Regards, Mukut

Yes, it appears to be possible (although rather slow) to use an IR sensor for mapping and navigation, as described in this blog post:

ROS is supported on ARM on Ubuntu 14.04, so I strongly recommend running Ubuntu 14.04

Yes; you can use wheel encoders for odometry. The specifics are fairly detailed, and warrant a new question. (There are also LOTS of good resources online)

Ahendrix....can u give me a link for downloading an image with ROS indigo for rpi2? Coz it's quite a difficult job to get it done from source....and u know how slow is the internet over here in India and hence takes a hell lot of time....

I don't own a raspberry Pi 2 and don't have an image for you. I STRONGLY recommend that you use Ubuntu 14.04 and the UbuntuARM instructions instead of building from source:

This has gotten pretty off-topic. If you have more questions that are not about IRDAR, please ask a new question.
