I am working on a robotic assignment with RCX by legOS.
It is a small RCX vehicle that move around.
I want to add a goal for this vehicle.
Say, move towards a certain direction.
However, all the 3 sensors port had been used up for some purpose.
So I am considering if I could use the IR port on the RCX to produce a goal.
???Lead the vehicle with a infra-red beam???
Sadly, I am not familar with the infra-red command in legOS.
Could anyone of you give me some guidelines or suggestion?
Thanks a lot

| (...) If there is no way to free an input port for a light sensor you can try other ways with IR. You could use a PC to send messages to the RCX "turn left", "turn right", "slow" and so on.

| (...) You might try this: stand two mirrors on edge at 90 deg to one another. This creates a corner reflector which will reflect light back in the direction from which it came. Have the robot first search for this reflection and then move toward the (...) (24 years ago, 16-Feb-01, to lugnet.robotics)
