i want to make a robot that can clean d floors........kinda d roombha but d problem is that how do i map d room ? so tat it knows that it has cleaned this part of d room already......
so far i m familiar with d arduino n 8051 microcontrollers....... n electronics
plz hlp me
thanks in advance  !

if this project is not suitable for me as i am a newbie...... plzz atleast tell me ...... n plz do suggest robotic projects of my level.....

Mapping a room while you're moving about it is called "SLAM" (for "Simultaneous Locating and Mapping" IIRC.)

There are some functions to do SLAM in the ROS toolkit. It requires a lot more computing power than an 8051 or Arduino will have, though. Perhaps you could do it with a Raspberry Pi, or a small PC.

If you're not a skilled software developer, though, then this is probably not something you can achieve yet. It's pretty gnarly stuff.

thnx.... alot for replying i m jus a starter ....... bt i wud keep track of d words u said....... n try .......bt can any one suggest any good robotic projects...... n more information on mapping would be appreciated....... awesum site n awesum users

IMO it's best to start with switches on a bumper(goes straight until bumper hits, then turns).
as you get deeper into the project you could add mapping.

If you don't want to place the extra computing power hardware on the bot, I've heard people have had success writing the mapping code for a PC and then adding bluetooth to their bot. Even if you can't get it to work well at first, at least you've learned how to interface with bluetooth.

thnxxxx..... i probably would start with tommy's idea of d bumper switch............ n thn add mapping........ 
can u ppl tell me some mapping techniques?? 
n thnx 4 d reply.....
