Hi:

I need to know if possible
to use 6 Parallax RF transmitter (Parallax 433 MHz, Stock#: 27980 )

and one receiver (Parallax 433 MHz RF Receiver, Stock#: 27981 )

If it is not possible to use 6 transmoitters, I could use three of them.

But I don't know if it is possible.

Thanks, Joe confused.gif

    Joe,

    ·· I don't think this would work if you're planning on having them all transmit at the same time.· Could you describe what you're trying to do?

    Hi again:

    I need to know the possition of 3 robots (or more) using RF.

    And then I need to use transmitters and one reciver at the same time.

    I hope this can help.

    Thanks, Joe

    The problem that you'll run into is RF interference between the transmitters. If you can program the robots so that only one robot is transmitting at any given time, you should be able to avoid interference.

    You'll need an accurate timebase to synchronize the robots, and maybe a real time clock for each robot.

    You should use a transceiver setup.
    You should have the base station send a, report positon, commad to each of the robots one at a time.
    Each of the robots and the base station would need a reciever and transmitter.
