It's fine saying you have a remote with 8 function buttons but what do you want to do with them?

The tx functionality can be done with a pic, coded suitably to generate an IR pulse train whenever one of the buttons is depressed...the rx could be done with a pic also, decoding the incoming IR pulse train and then passing it to whatever control function electronics you have on your bot..

The transmitter and receiver pair alone are not sufficient.......they will only send and recieve data...

You need to encode the commands that your bot will respond to.....this is the data part.........

The use of tx/rx pairs is good in as much as it doesnt require "line of sight" as ir would......although my colleagues on the above mentioned forum have made several mods that reduce the directivity..range is good at around 30m
