Connect the Intelligent Brick to computer with the USB cable

It seems obvious and intuitive how to connect the robot and the computer. We must cover that part, so that we are sure you can download our programs to the robot later on.

Different jacks

The bigger jack of the USB cable goes into the computer and the small jack goes into the robot.
Upon successful connection you can see an icon on the top left corner of the display of the EV3 brick.

Fragile EV3 port

Be careful with the small USB port. Over time it wears off and the central plastic peace may break.


We've developed our program for moving forward and now we must download it on the robot. For this we'll use the USB cable. You can see that the jack at the ends of the USB cable are in different forms, in different shapes. This one is used for the computer and this one is used for the robot. We connect one end of the USB cable to the robot like this. You must be careful here not to break the port. It's not very easy to break it but it's also not that hard. So we first connect the cable to the brick again. Then we connect the other end of the cable to the computer. Now my computer is on my right so you can't see it on the camera but we just connected the USB cable to the computer. After we connect it on the brick screen there is an icon, you can see the icon right here at the top. And this icon tells you that you've successfully connected the brick to the computer.
