I want to get one EV3 large motor to copy the other. So if I move one half a rotation the other copies.

    Hi Nixtoo, can you share what programming language you're using and what you've already tried? It will help to get better answers. – MindS1 Feb 24 '19 at 20:33

I would make a own block (turquoise) and move motor a and b in that block. You can make two parameters for speed and revolutions

EDIT: Now you can control that motor-couple by using that turquoise block.

  • Hi Sadap! I have interpreted the question as if the first motor should be passively accepting any rotations, and the EV3 should play these rotations back on the second motor in real time. If Nixtoo sees this, they can decide whether this reflects their original intent or not and give appropriate feedback. – zovits supports GoFundMonica Apr 15 '19 at 19:45
