Roboversity - IUCEE challenge: Problem statement for Grand Finals in Bangalore

The Main objective of this competition is to develop a Smart City by advancing from the concepts learned in the Solar and Smart energy workshops.

Apart from coming up with your own innovative ideas in your SMART CITY model, there are some criteria to be completed in order to qualify and get bonus points for the competition. The arena shown above must be a necessary part of the Smart City model to be developed by you.

Basic features of Smart City:

In the arena above A, B, C, D, E, F, G and H are different locations of the city. The other noticeable parts are the LCD display, two traffic light signals and a Smart Street light

Task 1

Vehicles approaching from location A have two roads to reach location G. The primary task is to count the number of vehicles at zone D and zone E which are waiting for traffic signal and analyze the traffic density at both places D and E. Then the traffic density information has to be displayed using LCD display near the zone A itself so that the vehicles can be guided to take the least traffic path and save their time.

Task 2

The limit for the length of a vehicle to cross zones D and E is 20 cm. Lengthier vehicles should pass through zones B and C. If any of the vehicles more than 20 cm length violate the traffic rules, by passing through zones D and E, then a buzzer should ring at the same point on corresponding locations. Also to be considered is the 4cm/s average speed of a vehicle.

Task 3

There should be LED smart street lights placed at zones D and E. These should be working in a Smart way as explained below:

• Whenever sunlight/external light is there, then the Street light should be in OFF condition
• If the traffic density is very less (1 or 2 vehicles) at zones D and E, then the street light should be glowing with less intensity. Whereas, if the traffic density is high (more than 2 vehicles) at these zones, then the street light should be glowing with maximum intensity.
  Hint: This can be done using PWM of microcontrollers

Task 4

LCD display should be showing two status conditions combining points 1 and 2.

• For the first 5 seconds, it should be displaying the traffic density on both zones D and E.
• For the next 5 seconds, it should be displaying the traffic rule saying that the vehicles of more than 20cm length should pass through zones B and C only.
• These two status conditions should be continuously updated and displayed using LCD, in a loop.

Note: There is no need to create real Traffic Lights near Zone D and E as more number of port pins of microcontroller may be wasted to show only that traffic light in all directions. So place just a Dummy Traffic Light at these points.

Final Project

In addition to the successful execution of the primary tasks mentioned above, your Smart City will be judged on the basis of the implementation of more creative ideas that reflect our aim of Energy Conservation and efficient usage of Alternative Energy Sources. There is no limitation for including your creative ideas in Smart city.

Rules Of The Competition

1. Participants must use Skyfi Labs Embedded Development Board , which was given during the workshops for this competition
2. The participants must include the Heart of the Smart City (arena shown above) in the schematic of their final solution.
3. The maximum limitation of power supply given to this smart city can be 12-14V.
4. Additional components can be used by the participants for the implementation of their solution, if required. But, only Skyfi Labs Embedded Development Board can be used as the microcontroller core.

Judging Criteria

1. The execution of all the 4 primary tasks is mandatory for each team's Smart City to be considered for further judging.
2. Innovation and implementation of the creative ideas included in developing the Smart City in addition to the 4 primary tasks will bear maximum weightage
3. Presentation of their Smart City
4. Design and Construction of the City
