Robot Specifications and Rules

1. The robot must confirm to the maximum dimensions of 20cm width, 30cm length and 20cm height with all the sensors included and arms included and extended.

2. ONLY Arduino based controllers are allowed.

3. Robot must be self-navigating; no remote controlling is allowed.

4. The robot must be wheeled or tracked. Airborne platforms are not allowed.

5. The robot must be designed and built only by the participants. Off the shelf kits are not allowed other than the following. a. Drive gear (wheels, gear box. motor)

b. Sensor module (IR, Sonar, etc.)

c. Processing Development Boards and microcontrollers.

6. The maximum allowed voltage is 40V which should not be exceeded. 7. The robot must include a power on switch and a start switch. Once the start switch is activated no human

interaction is allowed. The participants should introduce the start switch to the judge board at the beginning. 8. The robot should be able work in the ambient light condition in the playing field. 9. Each team gets three rounds. At the beginning of each round a calibration time of 30 seconds is granted. The

participants can calibrate or make changes to the code at the presence of the judge board. 10. “Hard coding” to the robot is not allowed and all the codes must be provided to the judge board for review.

Playing field and the general description. • At the beginning of each round the robot should be placed on the starting square. With signal of the judge board

the START switch should be activated.

• Then the robot should follow the black line on the white background. The black line has a width of 2cm and the background is white.

• A Y-junction is ahead and the robot can take whichever path it can. This does not affect the race time as both the paths have the same distances.

• Then the robot meets a cube of 5cmx5cmx5cm blocking the road. The box can be RED or GREEN. The judge board will swap the colors randomly.

• The robot should detect the box and pick it up without damaging the box. Then it has to read the color of the box.

• After picking the box and reading the color, the robot then moves forward until it meets the unloading area intersection.

• The robot should place the cube on the left or right unloading areas according to the color. If the robot picked up a RED box it should place the box on the Right unloading area and if GREEN the cube should be placed on the left unloading area. The rail gate opens only if the correct color box is placed on the unloading area.

• Accidents with the rail gate can cause to end the round.

• After the rail gate there is ramp that the robot should climb and descend. The black line(path) is continued on the ramp too.

• The black line has the same width throughout the whole path. There are sharp 90 degree turns and acute angle turns.

• At the end the robot should come to a stop automatically at the end circle.

• The team that completes the round in the shortest time wins. Additionally, appreciations will be awarded to smartly engineered designs.

• In the trial session the participants can calibrate their color sensors and the line sensors with the test field.

• The decision of the judge board will be the final decision.
