Hi Stephen, you will not have success with this approach, because the LEGO firmware has no collision detection (especially no collision avoidance !) for their IR protocol. So if you're using more than 2 IR devices with LEGO firmware you will receive (...) (23 years ago, 27-Apr-01, to lugnet.robotics.rcx.nqc)
