Building an RF Transmitter and Receiver
« on: May 29, 2016, 10:50:57 AM »
Hi, I'm new to this forum.

I'm trying to build a RF Transmitter and Receiver circuit for an omni-wheeled bot that looks and moves like one https://www.youtube.com/watch?v=5vJCucpVdX0 Using continuous rotational servos. 

I'm finding the RC theory a little difficult and am hoping you guys can help me to understand it better so I can get a schematic together.

I need the servos/omni-wheels to be able to go forwards, backwards and stop in the way that the joysticks and knobs on the commerical transmitters would allow for. I'm thinking a momentary on-off-on toggle switch would allow me to do this?
I know I can use pretty much any frequency for the TX RX module as I'll be operating the robot by myself away from other RCs, so interference won't be an issue.

Knowing all the components needed e.g. diodes, transistors, capacitors etc. and putting them all together into a circuit diagram I'm not so sure about.  Should I end up with something similar to this:  http://www.wzmicro.com/rf.htm

Grateful for any help you can give, thanks.
