The goal of the city racer competition is to design a challenging and interesting environment for U14 and U19 students. Students develop a robot that can track a line, manipulate small objects, and traverse uneven terrain.

City Racer - Laws of the Game

The following laws describe the specifics of the city racer event. For general specifications relevant to all FIRA Youth events (e.g., robot dimensions, playing field and lighting, responsibility of the referees) please refer to General - HuroCup Laws of the Game.

[CR-1]: Field of Play

[CR-1.1]: The city racer competition is played on a field with a minimum dimension of 3.5 m by 1.5 m. See Fig. City Racer Field.

The sports field (court) will be composed of 9 pieces 600 mm square white foaming board and 10 mm high, the black line will be 18mm wide, might be arranged as the picture above. The arrangements could be changed by the referees. The field will have different kinds of material ex: woods, plastic…etc, and will be colored for a different mission.

[CR-1.2]: The field divided into 9 areas. B and F area are the required missions area, included T1, T2 , T3 color cards (T1, T3 are for directions and T2 is for the number of laps, the referees will announce the details. For example, a red card on T1 may mean turn right at the next intersection or yellow on T2 may mean three laps in total, whereas red on T2 may mean 1 lap only). Area C is the area for weight lifting. robots are required to lift the barbell and put it in the target position. Area D and area E are for the track field event. (The referees will announce the meaning of the T2 cards - how many laps the robot must follow around the track). Areas G and G1 are for football. The card T4 indicates the target area for the shot. A ping pong ball will be used as ball and placed on penalty marker; G1 is the goal area with three different directions. Area H is the jumping pit. Area I is the goal.

[CR-1.3]: The width of all lines is approximate $L

[CR-2]: The Lifting Bar and the Weights

[CR-2.1]: BarbellD:\0_個人文\robot\2017細部規則草案\IMG_4219.JPG

The barbell is a bolt (about 9 mm, made from iron, length: 40 cm, weight: 270 grams) plus two screw nuts and two plates, total weight: 370 grams. Weight: CD-R*2 (Diameter: 12 cm, 1.2 mm thickness, 17 grams). Barbell’s base: the base will use 1.2 cm width tape (diameters: 7.6 cm) then put it horizontally on each side ( as the picture above). The barbell has 3 different level weight:

  1. Feather level: each side with two CDs, taped with blue tag
  2. Light level: each side with four CDs, taped with orange tag
  3. Heavyweight level: each side with six CDs, taped with red tag

[CR-2.2]: The lifting bar is a wooden, metal, or plastic bar with a width between 8 mm to 15 mm. Two stops are used to mount the weights. The distance between the inner stops is at least 40 cm. The total length of the lifting bar is between 50 cm to 80 cm.

[CR-2.3]: ] The “weights'' used in the competition are standard 5 1/4 inch CDs or DVDs that must be lifted by the robot as seen in Figure Lifting Bar.

Barbell description

[CR-2.4]: Lifting height level: $WLH. The lifting bar must be put on a target location $WLD in front of the middle of the barbell.



Figure 3: Weight lifting target location for U14 (Left) and U19 (Right). The locations have a diameter of approximately 6 cm (Packing tape).

[CR-3]: Track and field

The track and field event uses colored cards with the following colors: red, yellow, or green. T1 and T2 will put at the intersection’s right side. The color of the card indicates the direction at T1 and T3. For example, color1 may mean turn right. The referees will announce the exact color and its meaning before the competition. T2 uses one of three colors to indicate the number of laps.


Track and field

[CR-4]: Shoot football(ping pong ball) and field

The referees will announce T4 card’s color which is for the shooting direction. The gate is made from 10 aluminum cans (330 ml). Ping Pong ball will be put on the bottle top (3.2 cm*1.2 cm), ping pong’s size is 4 cm.


[CR-5]: Jumping pit

The field’s size: 300 mm*400 mm, made from PVC board (thickness of 2 mm), surrounded by phone wiring duct type 3. The jumping pit will be filled with 3 mm to 8 mm plastic balls (200 g to 600 g, measure by the size and weight of balls, the referee will decide)

H area will put aluminum cans each side, the referees will announce the quantity.


Except the starting and the goal area, others will be white. The venue’s black trajectories’ have a width of $L.

The robot must cross the jumping pit from one side to the other. It is only allowed to enter and leave the field from the 40cm wide side lines

[CR-6]: Number of Robots

[CR-6.1]: A single robot competes in a match.

[CR-7]: The Players

[CR-7.1]: The robot in its maximum extension must fit into a cube of size $RL by $RL by $RL.

[CR-10.1]: Sports Items

  1. The robots start from A area, any part of the robot cannot cross this area before the referee has started the trial by blowing the whistle. The robot must be placed completely in the starting area.
  2. B area: the required missions’ area, T1 is for the sports, T2 is for number of laps.
  3. C area is for lifting. Robots are required to lift the barbell and put it in the certain position. Different age classes have different target height.
  4. D and E area are for the track and the field; follow the direction from L1 to L5.
  5. F area: the required missions’ area, follow T3 card’s instruction.
  6. G and G1 area for football, T4 card is for shooting direction.
  7. H area is the jumping pit.
  8. The robots should be stopped at I area (red zone).
  9. The referees will announce all the colored cards’ content.

Different groups’ sports item detail will be announced by the referees. The sports item will be announced before the assemble time and will announce the colored cards color and position before each round.

[CR-10.2]: The maximum time for one trial is 5 minutes.

[CR-11]: Method of Scoring

Scoring: Sport items points and time points; the referees will score each performance of the robots.

[CR-11.1]: The field will divide into 9 major squares, after pass each part will have one score. The robots need to finish the sports items by order.

[CR-11.2]: A area: started from here, will get 50 points after getting in the B area.

[CR-11.3]: B area: the referees will announce T1 and T2 colored card, the robots should complete the T1’s instruction can get 50 points.

[CR-11.4]: C area: If the robot successfully lifts the weight bar off the ground, it will receive 20 points.
