Receiver & Transmitter pairs

Help & Support Robot Parts

Hello,

I’m a mechanical engineering student and I’m making a small tracked vehicle for a project and the only electronics knowledge I have is from whatever I have googled. Without going in-depth into the project, I basically need to control this robot wirelessly and I require 3 receivers on my robot, each controlling a DC motor through a single-motor controller. The reason I need 3 receivers is because each of these motors will be isolated from the rest of the robot, i.e., no wires can connect to a main receiver. So i was planning on having 3 sets of transmitter/receivers and putting them on a single breadboard. I’m not looking to make this project efficient, just need to make a cheap proof of concept.

I’ve been looking at the cheap transmitter/receiver pairs available on this site and found the 315MHz and 433MHz versions. I however require a third receiver/transmitter and so here is my question: are these pairs available on the different channels of say, 433MHz for example? How would I go by doing this to make sure I don’t have interference between my 3 motors?

This might be a little confusing…so let me know if anything is unclear.

Thanks,

Chris

For the inexpensive transmitter / receiver pairs, you will still need to have a microcontroller, and as such, you can program the microcontroller to only act if it receives a certain code. If you have one transmitter and three receivers (each connected to their own microcontroller), the transmitter can still say “motor 1, turn on” and the other two motors will ignore the command. Any chance you can give a bit more info about the project and why the three sections cannot have any contact with each other?
