Or is it a 2 way protocol ? You analyze the IR remote only to find out wat key is what command ? Yes - not 2 way. The remote can work in two ways. One, as an actual remote -- press, direction keys, speed etc -- like an IR "radio controlled" robot -- very klunky. OR - you can press "program" mode and enter a sequence of keys (like BigTrack).  When you've entered them all press GO and the robot does them in sequence -- up to 64 commnands. When programming a sequence UP RIGHT LEFT etc, the robot beeps after it receives each instruction, no matter how long you press the key on the remote for.  Having scoped it, what seems to happen is that the key is sent continuously whilst the button is pressed. The robot ignores commands that are the same.  So UP UP UP is ignored and what happens is that from the first UP it continues to go up until a different (STOP) command is given. Will wire up a basci IR transmitter and see if I can at least make it respond to the UP (forward) command --- from there, just a matter of getting all the keys. All that said, the thing is 40 years old and during this testing so far I've managed to break the wire / solder, so some fixing is needed firt. N
