Andy,
This won't happen if the Device_ID to Device_Friendly_Name mapping is as
generic as "motor1", "motor2", "light1", "lightsensor1", "irdar1",
"rotationsensor1", "rotationsensor2" and so on...
Then, the *specific* Device_Friendly_Name to Robot_Device_Location mapping
should be done at the source code level (as it is done now, when I say the
the LEFT_ELBOW = OUT_1).
Today, you have to pay attention to which motor/sensor is connected to which
port so everything goes ok with your robot.
With the system we are talking about, you should pay attention to what
devices are where in the robot, and not to what port are connected.
Just by looking at the "friendly name" written by you on the device instead
of looking at the port letter/number.

This is fine for computer systems that change
infrequently, but for
lego that is intended to change often, it's not
ideal. There is a linkage between the programming
and the specific motors or sensors. If you take
your machine apart and then rebuild it later, the
same devices must be used in the same locations;
switching the original drive motor for an arm
would have serious functionality issues!

| Marco, Yes, I agree that logical mappings will help the problem. But consider this example: You have motors with the friendly names of motor1.. motor20 You write a program and specify the associations: left arm = motor1, right=motor2, etc. I believe (...)
