Problem Statement
Make an autonomous robot which is able to traverse through the given track in the minimum time.

Introduction

Conquering speed has always been an addiction for man, for it means pushing back a boundary and fighting against limits of mankind. So for all you speed lovers the time has come to design an autonomous robot which races on a given path of black line with different thickness in the minimum possible time. Let your masterpiece race against time at Epiphany 08


Arena
1. The arena would consist of a white chart paper on which racing tracks would be made by black electric tape of varying thickness.
2. The thickness is as follows:
(I) AB=IJ=KL=MN=3cm
(II)CD=EF=GH=1.5cm
3. The paper would be placed on a plane surface. Do not worry about irregularities on surface. We will take care of it.
4. The light in the room would be normal and the arena would be placed inside a closed room so if you are using a sensor which is affected by visible light (e.g. led ldr pair) then please cover your robot properly so that it is not affected by room light.
5. There would be 3 small arena’s provided to you so that you can do testing and troubleshooting before the start of main event.
6. Also a computer would be provided for burning your program. Do bring your software and hardware to burn. Also bring your software on CD and not on any PEN DRIVE.
7. Regarding power supply, we will just provide 220V AC power supply.
Batteries, extension cords, solder and all other material related to robot must be brought by the participants.

Specifications
1. The Robot should be able to fit inside a cube of 30 * 30 * 30cm at the start of game
2. The Robot is not allowed to expand during the game play
3. There is no restriction on microprocessor and programming code used.
4. Lego kits are not allowed. However readymade gear assemblies and microcontroller kits are allowed.
5. There should be no use of any technology which harms the arena in any way. The robot should also not leave anything behind. Organizers reserve right to disqualify any robot on basis of harming the arena.

Rules
1. The robot should be able to move by itself on a given track, that is, it should be completely AUTONOMOUS.
(The total time to traverse the course is 150 seconds. Scheduled Time is 15 seconds per checkpoint.
2. Team Size: A team may be of maximum 4 participants. Participants from different institutions can form a team. Team member should have valid educational institute ID card.
3. There will be a trial run given to the participants before the start of the event. An extra time for calibrating values for sensors would also be given.
4. Once the timer clock of the main event starts you are not allowed to touch or control your robot.
5. Adapters/batteries should not exceed the ratings of 12V and 24W.
6. If your robot runs out of the track then you will be given another chance to fix your
Robot, but this fixation time cannot exceed 2 minutes. After 2 minutes if the team is unable to get back to arena, it would be marked disqualified. This second chance would be considered final and no further chances would be given.
7. In case of any dispute, the decision of organizers would be considered final.

Marking Scheme
1. The marking scheme is divided into two heads MARKS (A) and MARKS (B).
Total marks would be sum of MARKS (A) and MARKS (B)
Flags
Total Marks(A)
Checkpoint 1
25 marks
Checkpoint 2
25+50 = 75 marks
Checkpoint 3
75 + 100 = 175 marks
Special Checkpoint
250+75 = 325 marks
Checkpoint 4
175 + 200 = 375 marks
Checkpoint 5 (end)
375 + 250=625 marks (Checkpoint 3)
Checkpoint 5 (end)
325 + 200+250=775 marks (Special Checkpoint)

NOTE: In the race you have to travel either “special checkpoint” or “checkpoint 3”.Also for securing marks in higher checkpoint (e.g. Checkpoint 2) you have to traverse through the lower checkpoint (e.g. Checkpoint 1)

2. Now for securing maximum MARKS (B) you have to cover the track in minimum time.
Formula for Marks (B) = (Scheduled Time – Time Taken)*10{TO BE CALCULATED PER CHECKPOINT}

If you are unable to complete the track then you will get marks B according to time taken and scheduled time according to checkpoints you have covered.

For example your robot is unable to move after check point 2 and you took 15 seconds(5 for 1st checkpoint and 10 for 2nd checkpoint) to reach a distance up to checkpoint 2. Then your marks in marks (b) head are [(15-5)*10 + (15-10)*10] =150
3. The team with highest marks is the winner
