Before we begin#
Tip
To ensure that your streets will last long, make sure to follow these steps:
Clean the tiles with a mixture of water and soap, or alcohol, and let them dry completely before attaching tapes.
Place the yellow tape on the tile and cut out pieces rather than pre-cutting them. This ensures proper adhesion by preventing loss of glue.
Straight Roads#
Each straight road segment has:
Solid white markings on the outer sides of the lanes (right of the direction of travel).
Dashed yellow markings at the center.
Each lane is 21 cm wide (from the end of the white to the beginning of the yellow).
Assembly#
Place the yellow tape in the middle of the tile as shown in
fig:tile_instruction_straight_1.Ensure the yellow tape is properly centered, with a distance of 27.25 cm from the tape’s edge to the tile’s edge, as in
fig:tile_instruction_straight_2.Cut the yellow tape into 2.5 cm pieces, starting 5 cm from the tile’s outer edge.
Add white lane markings at the outer parts of the tile, 21 cm from the yellow tape, as in Fig. 37.

Curved Roads#
Each curved road segment has:
Solid white markings on the outer sides of the lanes (right of the direction of travel).
Dashed yellow markings at the center.
Each lane is 21 cm wide (from the end of the white to the beginning of the yellow).
Assembly#
If you have a laser cutter, use the provided file Duckietown Curve Tile Construction template. Without a laser cutter, mark a quarter-circle path for the yellow tape using a string. Follow the guidelines for tape placement and lane width measurements in Fig. 38.

Intersections#
Each intersection (3- or 4-way) has:
Solid white markings on the outer sides of the lanes.
Dashed yellow markings at the center.
Solid red markings for stop signs.
Each lane is 21 cm wide.
Assembly of 4-Way Intersection#
Place four yellow tape strips, centered and extending 6 cm from the tile’s edge.
Align red tape horizontally with the edge and cut it to 21 cm, as shown in
fig:tile_instruction_4way_3.Cut yellow markings into 5 cm pieces and add white tape at the corners.

Assembly of 3-Way Intersection#
3-way intersections follow the same process, except one edge uses white tape instead of red and yellow. The result can be seen in Fig. 40.

Troubleshooting#
Troubleshooting
SYMPTOM
My tape tends to detach from the tiles. The glue is no good.
RESOLUTION
Follow these steps:
Clean tiles with a water and alcohol solution to remove residual oils, and dry them completely.
Apply tape directly to the tiles and cut on-site to maintain glue strength.
Use a heat source (e.g., a hair dryer) to warm the tape after application, softening the glue for better adhesion.
