You need to give us more information. How exactly is your robot configured? Do you have a holonomic drive system (omni or mecanum wheels)? If you do not, there is no way to "move" left or right. Do you mean "turn" instead? What code do you have so far? Have you taken a look at the relevant lessons on this page:
