This robot looks a bit weird. Can you guess why? The motors are placed in opposite directions. One of the motors is facing "forward" while the other one is facing "backwards". This means that if you tell both motors to rotate forward the robot will just rotate! To make the robot move forward, you will need to make one of the motors rotate forward and the other one - 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 and this needs to be accounted for during programming.
