THE LINE CRAWLER


ABOUT THE EVENT

Design and construct an autonomous robot which is capable of traversing the arena by following a line in a particular manner and avoid the obstacle that it might encounter. The participants are required to build a line following bot which is capable of detecting an obstacle in front of it and sense the presence of colour on the floor in front of it.
Traverse the area from the START point to the STOP point by following a black line laid throughout the white area. But the task is not that simple. The bot should be capable of following a particular pattern as mentioned further in this problem statement. The bot should work on the principle of advance line follower to give utmost efficiency on the arena. During its operation, the bot will encounter the various obstacle which it needs to understand and take action accordingly. Performing every task smoothly will result in full point and violating it will result in penalties.....

EVENT STRUCTURE

ARENA DESIGN & SPECIFICATION
• Arena will be absolutely flat and leveled out so additional power is not required to run the bot. Although participants can vary the speed of their robot to give maximum efficiency in following the line.
• The Surface of the arena will be painted white and the bot is required to follow a black line of thickness 2 centimeters.
• The Arena will contain various checkpoints, completing which will result in addition points. After any checkpoint if the bot deviates from its path, then the bot will start its journey from the last check point.
• The contestant will need to program their bot so that it is capable turning clockwise or counter-clockwise at exactly at the angle required at each key points of the arena. Failing which will result in negative marking.




KEY POINTS
There are some key points of the arena that the participants need to keep in mind while programming their bot to gain maximum points and avoid deviation from the required path.
At some point in the area, the black line will not be continuous and there will be a gap of not more than 5 centimeters. There will also be a sharp turn after some gaps. So the participants should program their bot in such a way that it does not malfunction at these given points.
As the image suggests, at some point of the arena the line shift suddenly to either the right or left by not more than 1 centimetre. The participant needs to program their bot in such a manner that it could understand the shift and traverse the path according to the blue line shown in the image.
At some points of the arena, the lines will have sharp turns but the edges of the turn will be removed as you can see in the image beside. So the participant needs to program their bot in such a way that it does not malfunction in this part.
At some points of the arena, the path could have a turn with an angle of at most 45 degrees. So the participants will have to program their bot accordingly. If the bot leaves the path, it will have to restart from the last checkpoint and penalties will be imposed for every such action.
Some part of the arena will constitute curved dotted lines with gaps of maximum 1 centimetre. The line will not bend with a very sharp turn but will almost look like a straight line. So the contestant need not worry so much about this part as they will easily be able to traverse with a minor change in the program.
COLOUR SENSING
There will be points in the arena where the line will divert into two paths at 90 degrees. At this point, there will a rectangular patch of red colour laid on the floor 3 cm ahead of the turning point as shown in the diagram. The participant needs to construct their bot and program it in such a manner that it should be able to detect this colour in front of the line and take 90 degrees turn to the right side. Taking a left turn in this point and following the path will result in negative points. If the right path is traversed, the team will gain points in their favour.
When patches of blue colour will be present on the floor in front of the line the bot should take a 90 degrees turn to the left side and follow the path and taking a right turn will result in negative marking. Skipping the blue patch and following the wrong path will result in negative marking. If the right path is traversed, the team will gain points in their favour.
ROBOT SPECIFICATIONS
• Robot must not contain any ready made kits or Lego kits or any such assembly.
• However ready made micro-controller boards, sensors, chassis, gears and shafts may be used.
• The voltage difference between any two points on bot must not exceed 24 volts.
• The robot dimension must be limited by 20cm x 20cm x 20cm.
• The robot must be completely autonomous. - It should not receive any input from outside the arena.
• The robot should not contain more than 6 IR sensors for fair competition.
• Motor RPM should not exceed 200.
TECHNICAL DETAILS
• Team members will not be allowed to touch any part of arena, only organizers are allowed to handle the arena in any situation, the team will be disqualified whose member is found touching the arena.
• Teams will not be allowed to change robots mechanism and parts once the game starts.
• Participants are not allowed to keep anything inside arena other than the bot.
• During the run, the bot should not damage the arena in anyway. It is not allowed to leave anything behind or make any marks while traversing. All machines found damaging the arena will be immediately disqualified. The final decision is at the discretion of the organizer.
• The time measured by organizers will be final and will be used for scoring.
• Time measured by participants is not acceptable for scoring.
• Organizing team will not be responsible for any kind of damage to your bot.
• Organizers decision will be final and binding in case of any dispute.
• Organizers reserve the right to change any of the above rules they deem to be fit.
• The participants will be provided with 220 Volts, 50Hz standard AC supply if required but it is advised to construct a bot containing a self-powering mechanism.
• Participants will have to themselves arrange for any other power supply required for their robot.
• There may be slight variation in dimension of the arena.
• The arena & colour pattern may be different from the picture shown above....


RULES & REGULATIONS

TEAM RULES
• This event is restricted to students currently studying in any recognized Educational institute.
• A maximum of four participants are allowed per team.
• Students from different colleges can be a part of same team.
• An individual cannot be part of more than one team. Participants must bring a valid identity card of their institute and KIITFEST ID.
PRELIMS
• Prelims will contain only some key points of the problem statement and the participant ability of building a perfect line follower will be tested. This will a qualifying round in which contestant will compete each other to qualify for the finals and get yourself one step closer to the winning prize!!
• Two dry run of 8 minutes will be given followed by one final run of 5 minutes. The dry run will help the participant anticipate any change in the program that they might need to do to make their bot more perfect (Any change in the construction is not allowed). But they cannot take more than 5 minutes or leave the arena during their dry and final run, otherwise the team will be disqualified.
• The score of only final run will decide if the participant qualifies in the next round or not. And only one final run will be made and the scoring will be final under every circumstances.
• If the bot deviates from the path, it will have to start again from the last checkpoint. Three such restart will be allowed, after that negative mark will be imposed on them.
• For completion of every checkpoint there will be positive marking.
• Completing the whole path of the prelim will result in additional points other than the checkpoint.
• Skipping is not allowed in the prelims. FINALS
• Finals will contain all the key points of the problem statement. This is where it will get really interesting. The Actual coding skill and teamwork of the participant will be tested and the challenges will not be as easy as the prelims.
• Similarly like the prelims, two dry run of 10 minutes and one final run of 8 minutes will be allowed.
• The score of only final run will decide winner. And only one final run will be made and the scoring will be final under every circumstances.
• If the bot deviates from the path, it will have to start again from the last checkpoint. Three such restart will be allowed, after that negative mark will be imposed on them.
• For completion of every checkpoint there will be positive making.
• Completing the whole path of the prelim will result in additional points other than the checkpoint.
• Any team can skip a checkpoint after 3 deviation but not directly. A maximum of 2 skips will be allowed with heavy negative marking.......
