DESCRIPTION

            Line follower bot is basically a line following competition. A track of black line on white background will be laid out and an autonomous robot has to follow that line. There will be two rounds, Elimination round and Ecotrack round. Elimination round will be a ‘LOOP TEST’. In Ecotrack round bot has to follow the ‘Globe’ like track and has to find the maximum numbers of nodes. Number of nodes identified, time taken to cover these nodes will decide final points earned by robot.




RULES

       The teams will have to submit their bot to the organizers before the start of each round. Only those teams which submit their bots will be allowed to participate. The bot will be handed back to the team during the time of their run. They will be given 2 minutes to do any hardware changes and calibration of the bot if they wish. If the teams are found to alter their code after depositing their bots, they will be disqualified.

  1. At the start of the task, the bot will be placed at the starting point. Only 1 member from the team is allowed to be near the arena while starting the bot.
  2. Timer will start when the organizer gives the signal to start.
  3. Rules about Restarts:
    • A maximum of 3 restarts will be given to the team during the match. After 3 restarts penalty will be there.
    • In a restart, the timer will not be set back to zero and will not be paused.
    • During a restart, a contestant does not allow to update the program. However, contestants are allowed to adjust sensors (gain, position etc.) and make repairs. A contestant must not alter a bot in any manner that alters its predefined specifications.
    • In a restart, bot will start from last checkpoints crossed. Participants can choose any previous checkpoints including start of the game. For Ecotrack round only Return zone will be restart point.
  4. Bot must blink the LED for 3 times at each node point. The LED should be strictly of high intensity and visible to naked eye.
  5. The bot should not scratch, damage or destroy the track or accompanying parts of arena. Bots which are found damaging the arena leads to disqualification.
  6. Each contesting bot is allotted 4 minutes run for every round.
  7. Each contesting bot is allotted 4 minutes for Elimination round and 6 minutes for Ecotrack round.

ROUNDS

    Round 1: Elimination round

    1. An elimination round will be held prior to the Ecotrack round.
    2. Elimination round will consist only passing the checkpoints and tracing the line. After completing Elimination round bot must stop on platform called Return zone by climbing ramp.
    3. The teams will be ranked according to their points.
    4. Top teams will qualify for the finals. Other than this, the performance in the elimination round is of no significance to the contest.

    Round 2: Ecotrack round

    1. In Ecotrack round bot has to follow the ‘Globe’ like track and has to find the maximum numbers of nodes.
    2. The one who identify the maximum numbers of nodes will be the winner.

    Rules for Ecotrack round:

  • The bot has to start from the starting point and move through any one of the path having a white surface and black lines to reach the ‘Globe’ .
  • After reaching the Globe, bot has to travel the Globe and identify the nodes.
  • LED should have to blink for 3 times as soon as bot detects a node.
  • If bot fails to blink the LED will not count as a node.
  • Negative markings will be there in case of blinking the LED for the same node which was previously identified.
  • After identifying all the nodes bot has to come back to the return zone marked in arena images.
  • The one who identify the maximum numbers of nodes will be the Winner.
  • In case of tie, the points that earned while travelling the elimination zone will be the factor for deciding the winner.
