The provided image shows a block-based programming interface. Describe the sequence of actions being programmed.

The program is designed to repeat a sequence of actions 4 times. Inside the repetition block, the following actions are performed:

• The robot moves right (`move_right`).
• The robot moves down (`move_down`).
• The current cell is filled (`fill_cell`).
• The robot moves left (`move_left`).
• The current cell is filled (`fill_cell`).
• The robot moves left (`move_left`).
• The robot moves up (`move_up`).
• The robot moves up (`move_up`).

After the repetition block, there is a conditional statement:

• If the current cell is clean (`cell_is_clean`), then perform the following actions:
• The robot moves down (`move_down`).
• The current cell is filled (`fill_cell`).
• The robot moves left (`move_left`).
• The current cell is filled (`fill_cell`).
