Advance mechanically with a sequence of four strides: left, right, left, right.
Move ahead robot-like in four steps following the pattern: left, right, left, right.
Take four robotic steps forward in the order: left, right, left, right.
Proceed forward with robotic precision, stepping four times as left, right, left, right.
March ahead with robotic rhythm, repeating the left, right, left, right step pattern four times.
