If to the right of the robot there is no wall, it needs to take a step to the right. Otherwise, it should stay in the initial cell.

This is a programming task. The goal is to instruct a robot based on its environment. Here are the available commands and their descriptions:

• move_left(): Take a step to the left.
• move_right(): Take a step to the right.
• move_up(): Take a step up.
• move_down(): Take a step down.
• fill_cell(): Fill the current cell.
• free_from_up(): Check if the cell above is free.

Task Breakdown:

1. Check the right side: The robot needs to determine if there's a wall to its right. This likely involves a function like is_wall_to_the_right() (though not explicitly listed, it's implied by the task).
2. Conditional Action:
   • IF there is no wall to the right, the robot should execute move_right().
   • ELSE (if there is a wall), the robot should do nothing (stay in the initial cell).

Example Pseudocode:

IF NOT is_wall_to_the_right():
    move_right()
ELSE:
    // Do nothing, stay in the current cell
END IF
