6. Differential Drive Quiz

      

        To make a 2WD differential robot execute a tight Pivot (Tank) Turn to the Left in place, how should the motors be driven?
      

      
A. Left Motor Forward 100%, Right Motor Forward 100%.

      
B. Left Motor Reverse (-100%), Right Motor Forward (+100%).

      
C. Left Motor Stopped (0%), Right Motor Reverse (-100%).

      
D. Both Left and Right Motors set to 0% Duty Cycle.
