★★★★★Build the maze
- Lane width: measure the tightest U-turn your car can make, add 10 cm, and use that as one lane width. Every maze is drawn in lane widths, so any size works.
- Walls: books, boxes or cardboard, 10 cm+ tall and solid.
- Green tile: a flat, matte green square one lane wide (paper, felt or tape) at the end of every maze.
- Line mazes (Missions 6–7): black tape about 2 cm wide on a white sheet or floor.
Tip: tune one number at a time — steering angle, roll distance, then the sensor limits.
