A robot is placed in a 5x5 grid. The robot's starting position is shown in the grid below by the arrow symbol ▼ at Row 2, Column 2, which indicates it is initially facing South (Down).
Squares containing an [Obstacle] cannot be moved into. The outer boundary of the grid also acts as an obstacle that cannot be moved into (i.e. ObjectAhead() evaluates to true if the robot is facing the edge of the grid).

Determine the sequential path of coordinates the robot visits from start to finish. Specify each step in order using the format (Row, Column).
