Which ports are generally used for which sensors/motors on the Vex IQ?
Welcome to the forum. You can use any port for any sensor or motor.
Since internally ports are grouped in triplets, for high power drain operations it might be a good idea to connect motors to different groups (1-3, 4-6, 7-9, 10-12)
If you want to use the built in controller program you should use the ports that are documented in the manual (1&7 for the left motor, 6&12 for the right motor etc…)
Thanks, Jetro, that is nice to know that ports are grouped like that. So, do motors used to drive the wheels take more power than do those who do lifting? Does substituting Omni wheels on the front of the chassis reduce the drag when turning enough to lower the drain on the battery through the brain?
Drive vs lifting: I don’t think you can easily say which draws more current/power. There MAY be commands in RobotC that let you monitor the current used by the motor. That would be good to look into.
Things like omni wheels do reduce the drag when turning, and lower the current consumption. How much, again depends on many factors. Sort of like asking if driving slower improves gas mileage. Maybe, but how much depends on the type of car you’re driving.
