How much is the difference in terms of the total power output, when I connect
all the four motors to the same port, vs. if I distribute them in pairs into two
separate ports?
When two motors are connected together, they end up synchronize with each
others, i.e., turning one causes the other to turn too. As the result, two
motors connected to the same port will turn in about the same rate.
So maybe this is a simple way to make a differential-steered vehicle that goes
straight: Connect both motors to the same port. To turn in place, use the second
port to flip a polarity switch to reverse the direction of one of the two
motors.
Cheers,

| (...) A single RCX can drive two 71427 motors at full power, but the built-in 500 mA current limitation (and probably thermal protection after that) will be triggered if you use more than 2 motors at significant load. For more details, see (URL) (...) (21 years ago, 3-Mar-04, to lugnet.robotics)
