2 IR controller usage

#1

I have 2 starter kit robots with IR controllers and would like to use them in the same room together - is there a way to set a channel on the 2nd controller so that it only controls the second robot independently from the first?
Thanks!

As far as I understand them, IR controllers, including this one, don’t really have channels; they just blip out coded pulses of light, on the same wavelength, sort of like Morse code. So the short answer would be “no.” The longer answer miight be that you could mess around with the pattern of the signals that it blurps out-the dots and dashes as it were-and code your own “controller a” and “controller b” signals on the send and receive side. That would be pretty far down the rabbit hole for this equipment though. Unfortunately, the data sheet for this equipment on their website appears to only be in Chinese, which is not very helpful for most of us here; I am also still waiting to receive my first IR robot kit from Ebay…

One thing I do notice looking at their IR receiver information page, is that their IR receiver can decode broadcasts on NEC protocol AND Phillips IR protocol. The Makeblock remotes use NEC’s patterns of dots and dashes, in other words, but they can also understand Phillips’ different system. Try picking up a Phillips remote and messing around with it, would be my advice. Might be an easy solution. http://www.pcbheaven.com/userpages/The_Philips_RC6_Protocol/

Thanks for the suggestion! I might end up trying to make one of them bluetooth if I can update the firmware and get the app working.
