My team’s robot utilizes 9 motors, but strangely enough ports 1, 2, 3, 4, 5, 6, 7, 8, and 10 are occupied and port 9 is empty. I always assumed that you could just switch around the motors in their ports and reconfigure them in the robot’s programs.
My question: does it make a difference in which port a motor, or a sensor, is plugged into the Cortex?
I don’t fully remember how we found it out, but it wasn’t anything quantitative. I think we had both two wire ports on one side of the drive and it curved to that side, and upon flipping the ports it curved to the other side. We also noticed something with the motor on it’s own in a 2-wire versus 3-wire port, but it was all just qualitative observations.
It was nothing major, but somehow we managed to notice it and it had an effect. I don’t think it really will matter, but I still try to keep the different ports on separate systems. Anyways, I’ve always wondered why the Cortex has the two 2-wire ports instead of all 3-wire?
Edit: Oh, and there is a speaker port labelled SPK at the bottom of the sensor ports, it’s not for a sensor, and the only place you plug the speaker in! I felt really stupid last year when I always read about some speaker port and couldn’t find it while staring straight at it…
