Strange Bot - LEGO Robot with two motors in reverse direction

This LEGO Mindstorms robot is strange. Can you guess what is strange about it?... The motors are placed in a reverse direction. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you make the robot move forward with a Tank Block in the EV3-G software it will just rotate. To make the robot move forward, you will have to make one of the motors rotate forward and the other one - rotate backwards.

The goal of this robot is to teach students that motors could be placed in many different ways. It is not always the case that the two motors face the same direction. Also, it is quite fun.
