Hello,
I have three small Automated Guided Vehicle wich navigate in a 700*700
square feet area. Using ŕ PC, i want to know at each moment where every one
of these robots is. What are the different method i can use wich give
precise results.
Thanks

Keep track of its motion, obviously, but maybe three transponders and
a little triangulation?

Good Luck!

In that size area a RFID tag on each plus three transevers might work .
It depends on if the area is empty or full of walls also.

Yes, the area contain many walls.

I'd like to throw my three pennyworth into the pot.

Would it be possible to lay a matrix of wires on the floor area and give
each robot a unique coded frequency fed to a coil in the base.

The X and Y wires could be interrogated for a pulse and the frequency would
denote which robot was over a junction.

It's just an idea, someone may be able to enlarge on.

Kind regards, Gordon.

With walls light based systems aren't really usable. So use some form of RF.

RIFD tags are smallish and already exist. Using a tranmitter on each unit
requires only that they have different frequencies and that the signal
proccessing used be differential . By comparing each receivers signal
strength against the other two you can form a location even if the
transmitter is weaker with time.More receivers will also give improved
location.

Either accurate Radio Direction finding with triangulation or have each have
a map of known obsticales and Ultrasonic detectors.
