4-0 Rules

4.1 Game Rules

NOTE - The teams will have to submit their maze solving robot before the start of the competition. Only those teams which submit their maze solving robot will be allowed to participate. 

The maze solving robot will be handed back to the team during the time of their run. They’ll be given 2 minutes to do any hardware changes if they wish. Under no
circumstances will they be allowed to make changes in their code.

1. The maximum time given for completing the task is 6 minutes. Only one run will be given to a team. Before the start of the run, a dry run of 5 minutes will be given to the maze solving robot. During this run the maze solving robot can explore the entire maze to find the position of
   the nodes and the bridges. The bot should give a visual/audio signal at the end of dry run. If the time for the dry run exceeds 5 minutes, then the extra time taken for dry run will be deducted from the allotted run time of 6 minutes. No advantage will be given if the dry run ends before 5 minutes. At the end of dry run the robot will be placed at the starting point.
2. Type B block has to be deposited in the block deposit zone which is at the centre of the maze. Type A blocks have to be deposited in the block deposit zones in the corners.

NOTE – No penalty will be awarded during a dry run if the bot crosses a node.
 
4-1-1 Starting Procedure

1. The starting procedure of the bot should be simple and should not involve giving robot any manual force or impulse in any direction.
2. Teams can have a separate onboard switch for restart. This switch will have to be shown before the run to the organisers.
3. The manual robot should not deliver/collect the robot/blocks beyond the central part, i.e. at any point of time, the top projection of the manual bot must lie in the central zone.
4. If any part of the block is in contact with the autonomous robot, the autonomous robot is said to carry that block. During the run, every robot can carry only one block.
5. During the run if any block gets displaced from its original location and lies somewhere else in the grid or central zone, it will be picked up and put back to any other random grid point. If the block gets displaced in the maze then, it’ll be placed anywhere on the check line 1 as per the convenience of the participant.
6. The maze solving robot must strictly use the principle of line following. 
7. Throughout the run, the manual robot should lie on the uneven terrain. This means that the point of contact of the manual bot with the arena must lie on the uneven terrain. It is however allowed to expand even beyond it in the central zone.

4-1-2 Checkpoint

1. There will be two checkpoints during the run.
                          First checkpoint - Once the robot touches the second block or crosses the check line 1 after depositing the first block, it will be counted as first   checkpoint.
                          Second checkpoint - Once the bot touches the third block or crosses the check line 1 after depositing the second block, it will be counted as second checkpoint.

4-1-3 Restarts

1. The teams are given 3 restarts each for every autonomous robot and the manual robot. However, there are no restrictions on the number of restarts for the dry run.
2. For every restart for the manual robot, the manual bot has to be put back on the  uneven terrain. If the teams opt for a restart for the manual robot which carries the block, then the robot has to be put back on the ramp and the block will be placed back randomly on the grid. In a restart, the timer will not be set back to zero.
3. During a restart for a grid solving autonomous robot, the robot will have to be restarted by putting it back in the grid starting point. In a restart, the timer will not be set back to zero. During a restart for a maze solving autonomous robot, the robot will have to be restarted by putting it back in the maze starting point. In a restart, the timer will not be set back to zero.
4. During restarts for autonomous bot(s), a contestant cannot feed information about the grid to the bot. However, contestants are allowed to: Adjust sensors (Gain, Position etc.), make repairs. However, a contestant may not alter a robot in a manner that alters its weight (e.g. removal of a bulky sensor array or switching to lighter batteries to get better speed). The organisers shall arbitrate. 
5. All restarts for autonomous robot(s) and the manual robot require the approval of the organisers before the robot(s) can be removed from the arena. If the robots were handled within the arena without approval, the run will be terminated.
6. A block is said to be deposited if any part of the block is in contact with the block deposit zone. Note that the robot should deposit all the three blocks in the three different zones.
7. If after the checkpoint, a team opts for a restart, the blocks that have been deposited
   before the checkpoint(s) won’t be placed back on the check line 1.

4-2 General Rules

1. Team members will not be allowed to handle the blocks. Only organisers are allowed to handle the blocks in any situation.
2. The team will be disqualified if the blocks were handled within the arena without approval of the presiding organisers.
3. The robot is not allowed to leave anything behind while traversing the grid. It should not make any marks on the floor of the arena. Any robot found damaging the arena will be immediately disqualified. Only two members of the team are allowed to handle the robots.
4. Participants are not allowed to keep anything inside the arena other than the manual tobot and autonomous robots. 
5. Laptops/personal computers are not allowed near the arena. Other Wi-Fi, Bluetooth, etc. devices must be switched off. The organisers hold the right to check for these devices and their usage.
6. The organisers may stop any robot at any time if they feel that it is performing, or is about to perform, any action that is dangerous or hazardous to people or equipment.
7. No robot is allowed to use any flammable, combustible, explosive orpotentially dangerous processes.
8. The time measured by the organisers will be final and will be used for scoring the teams. Time measured by any contestant by any other means is not acceptable for scoring.
9. In case of any disputes/discrepancies, the organisers' decision will be final and binding.
10. The organisers reserve the rights to change any or all of the above rules as they deem fit. Change in rules, if any will be highlighted on the website and notified to the registered teams.
