Notes

Initialize the step counter
stepsTaken = 0

// Step 1: Stand up
stand
stepsTaken = stepsTaken + 1 // Increment step count for standing up

// Step 2: Walk forward until it senses a wall
WHILE NOT at wall DO
step // Take a step forward
stepsTaken = stepsTaken + 1 // Increment step count
END WHILE

// Step 3: Turn around
turn // Turn 90 degrees to the right

// Step 4: Walk back to the chair
WHILE NOT at chair DO // We assume 'at chair' condition will be checked after walking
step // Take a step back towards the chair
stepsTaken = stepsTaken + 1 // Increment step count
END WHILE

// Step 5: Sit down in its original starting position
sit
stepsTaken = stepsTaken + 1 // Increment step count for sitting down

// Output the total number of steps taken
OUTPUT "Total steps taken: ", stepsTaken
