@Rich from the floor plan you initially submitted, no Furniture 1: IR BEACON (reciever) on robot 2: Transmitter "A" setup near door 3: Transmtter " B " setup near Charger( different code to A )

Robot moves to Transmitter " A " Once it detects Transmitter " B " it ignores signal from " A" and moves onto charger.

An idea only not tested

@Bravia, that's another suggestion to add to the pot of possible solutions.

I think we need a quick recap on all of the possible solutions as there are a lot coming up now and to be honest I'm starting to forget some of them. Hopefully I pick them all up but if I miss any please let me know.

1. Compass, wheel encoder method - more information required.
2. QR Codes for identification of location and route to docking station.
3. Colour tracking of walls and/or lights to guide to docking station.
4. Laser on docking station, sensor on robot to guide to docking station.
5. Pair of Pololu IR beacons, one on robot and one on dock to guide to docking station.
6. Distance sensors and Compass module to measure off of walls and objects to determine location of robot. Accurate floor plan used along with floor map to pinpoint robot (much like on video games map screens).
7. Xbee GPS module on robot and on dock to guide to docking station - more information required.
8. IR beacons in multiple areas and sensor on robot to guide to docking station.

I'm just about to have a look over all of the options, digest them, look up the parts needed etc. so hopefully I'll have a nice and clear understanding of them all (as so far I've only really quickly checked these latest ideas out on my phone and very quickly).

To all,

Someone's project with interesting info on IR Beacon use

To hard for me to understand but someone else might be able to pull something useful out of it that we can adapt for use with the EZ-B.

GORDON i build his complete robot and JOE is a friend of mine too

Also he made a wall beacon too

@rgordon nice find, I'll have a read through as that could come in very handy and the small IR beacon design looks like it's simple yet effective. I'll see what I can pull off the site (if anything) that we can use.

@rgordon ths is JOE'S robot i made awhile back using the create and that transmitter

irobot create using a beacon

That designs needs both for it too work

Yet another good site. Looks like a ton of good research and projects. It goes over a lot of what we have been discussing. This site plus the one I posted earlier may be just what we need.

Thats a great site,i saved it a long time ago and a lot of great info on all types of tracking,i tried one of his that look good,its been awhile and i dont remeber what my results i got from it.

i see his design in the year 2007
