Hi everyone

I’m building a robot , one of its main function is to do the following :

Go to a predefined destinations.I don’t want to Use path-follower because it clashes with another main function( avoiding obstacles ) . So i figured , one way to do this , is to get several (Transmitter\Receiver) pairs with different frequency for each pair.I’ll place Transmitter1 in destination1 , Tarnsmitter2 in destination2 etc. and place all the receivers in the robot.So when Receiver1 is activated the robot will go toward Transmitter1 (destination1) and so on .

My Questions are :

can i do that using :

RF Link 2400bps Receiver - 434MHz) & RF Link Transmitter - 434MHz

and

RF Link 2400bps Receiver - 315MHz & RF Link 2400bps Receiver - 315MHz

?

can i get a third pair with different frequency ?

Thanks in advanced :slight_smile:

Why don’t you try hooking up the transmitter to a micro controller, then you could have as many as you want (as long as they are flashign at different speeds).

You could also try to create a “lighthouse” like transmitter.

That way your robot would know what angle it is in reference to the transmitter.

This is one of they ways that aircraft find the airport.
