Have you seen an i2c gps module? If you find one let me know, i'll integrate it

I had an idea to get from point A to Boint B. You stick a target on a wall that the Robot can recognise with its camera say a coloured board or some sort of black & white square pattern. The robot then motors to the target stops when its a few inches away using ultrasonic radar. Then it knows to turn left or right to locate the next target in the sequence. To go back it follows the reverse route.

Or a simple line follower but I don't like the idea of marking my floor with a line. Well I don't mind but my wife wouldn't be happy!

Unless of course its an invisible line like an infra red line its a thought

I like tbe target idea. I don't think you will find GPS accurate enough yet. However., for inregrating gps, i don't think we need i2c, just Bluetooth. It could communicate to the driving pc. Ooesn't have to be through the board, just like cameras are not controlled through the board.

The moment I saw this thread I stopped everything and started to look for a GPS and I believe I've found one! I don't know if you can buy it... I don't seem to be able to open the shop... But here is the link. Maybe I can find more! To be continued! epic end of episode music

Update: found another one: GPS And another one: navigation board m3 url=http://www.ryanmechatronics.com/public_files/user_manuals/platforms/NavBoard/UM2000_NAVBOARD_M3_User_Manual_Rev_B.pdf(maybe one of the best until now)

Note: I don't pay attention to price!

That Nav board M3 could be just what im looking for, so as it communicates via ic2 im presuming that we could just read the data from the board and write scripts to navigate with it, i also noticed that the board comes with an onboard processor also so maybe that could do the processing and nav and just pass motor commands to the bot.....hmm interesting, i wonder would that be possible, would just need to figure out if the i2c is available when using the onboard nav system, maybe i will email them to find out.

What an expensive little unit. I saw this DSS Circuits one: i2c GPS Shield

Boy are they expensive. I am thinking it is cheaper to embed a used $100 netbook into the robot with a $20 USB GPS antenna instead.

Re: usb gps.. or a Bluetooth one like I said earlier. You can get them for like $25 on eBay. Well under $100 for name brand. Then it can just communicate over Bt to the computer running ARC. We just need a position object to talk NMEA protocol over a BT serial port. I am sure we can find C# libraries already written. I'll dig around since I am expecting a pair of BT gps receivers in the mail any day now.

I'm with thetechguru and don't believe a GPS unit will be accurate enough for any indoor robot and also what about receiving the GPS satelite signals indoors? Looking in more detail at RoboRealm this looks like exactly what I want to do
