What the car must do
- Reach the green tile with your S-Curve program — no counted turns.
- Keep a list called route: add R for every right turn and L for every left turn.
- At the end, show the list on the hub. The staircase should read RLRL.

Maze size
| Along the route | Whole maze |
|---|---|
| 2 → 2 → 2 → 2 → 2 lane widths | about 7.3 × 5.3 lane widths |
With a 30 cm lane width the maze is about 219 × 159 cm. Lane spacing is one lane width plus a wall.
Success looks like
- All four corners are found by sensing.
- The hub shows RLRL.
- Run the mirrored staircase: the hub now shows LRLR — proof that the car senses.
