Arena

The arena consists of two zones:

Zone A

The obstacles will be placed in this zone. The obstacles will be circular balls or cones. The total length of the obstacle course is 10 m. At the end of the obstacle course, there will be the shooting line.

Zone B

1. This zone is divided further into different regions having different points when the ball makes its first contact with it.
• a. Region 1: 0.5 m to 1.5 m from shooting line.
• b. Region 2: 1.5 m to 2.5 m from shooting line.
• c. Region 3: Beyond 2.5 m from shooting line.
• d. Goal: 3.5 m from shooting line.
2. The balls given to the participants that will have to be thrown will be of plastic. They will have a maximum diameter of 6.5 cm and will weigh around 60 grams.
   Refer to the track diagram for detailed information.
3. The event will be conducted in swimming pool of IIT Bombay and there might be disturbances on the water surface so do take these factors into consideration while fabrication of your machine.

Dimensions and Fabrication

1. The machine must fit within an area of dimensions 300 mm X 300 mm at the beginning of the game.
   Note: There is no restriction on the vertical height of the machine.
2. The external remote control is not included in this size constraint.
3. The onboard power on the machine must fit within the aforementioned box.
4. During the game, the machine cannot detach itself into multiple parts nor damage the arena in any way. The judges hold the right to subjectively determine if the machine violates this clause.
5. The machine cannot be constructed using readymade lego kits or any readymade mechanism. But you can make use of readymade gear assemblies. Violating this clause will lead to the disqualification of the machine.

Power Supply and Propulsion

1. In case of using electric energy for propulsion and drive, the potential difference between any two points of the machine should not exceed 24 Volts, at any time.
2. Use of air compressors is not allowed. However, the power supply must be non-polluting and must satisfy the safety constraints determined by the judges.
3. In case the machine is using a non-electric power supply, kindly get it approved from the organizers beforehand via email. Organizers are not responsible for inconvenience if approval is not sought.

Controls

1. The machine can be both wired as well as wireless. However those bringing a wireless machine will be given extra points on completing the task atleast once.
2. The participants building a wireless machine have to bring 2 remote controls of distinct frequencies or a dual-frequency remote control, which can be switched to either frequency just before the start of the run. This is done to avoid frequency interference with competing machines.
3. Wired bots should have the wire of length greater than 10 m and the wire should remain slack during the complete run.

Launcher

The launcher can be designed in any manner as desired if it satisfies the above mentioned criterions.

Game Procedure

1. The participant will be given a time limit of 3 minutes for the entire game.
2. The time will begin when the machine begins its run for the first time from the starting line.
3. The obstacle course has to be crossed by passing adjacent obstacles from opposite sides.
   Example: If obstacle 1 is crossed from the left then obstacle 2 should be crossed from the right or vice-versa. Failing to clear the obstacle course will lead to a penalty of points.
   If the obstacle course is not cleared completely then the machine will have to restart from the starting line i.e. if obstacle 1 is crossed from the right then atleast one of the remaining obstacles should be crossed from the left.
4. After the obstacle course has been cleared the participant can then take a shot from the shooting line specified in the track. See fig in arena specifications.
5. After taking the shot the participant has to return back to the starting line to reload the next ball and has to clear the obstacle course to take another shot. It is not compulsory to return back through the obstacle course, a straight path can also be taken to reload as quickly as possible.

Rounds

There will be two rounds for the competition.

1. Round 1 will proceed in the format specified above. Top teams with a maximum score will go into the second round.
2. In Round 2, participants have to take shoots from a minimum distance of 3 m from goal in a period of 3 minutes. The team with the maximum goals will win the competition. The obstacle course will not be present on this round. Incase of a tie the team with maximum points in Round 1 will be declared as the winner.

Scoring and Penalty

For each obstacle missed there will be a penalty of 3 points corresponding to it.

1. The points allocated for different zones are as follows:
   • a. Zone 1: 15 points
   • b. Zone 2: 25 points
   • c. Zone 3: 35 points
     Note: The goal post is included in this zone.
   • d. Goal: 50 points
   • If the ball is thrown out of the pool no points will be awarded to that shot.

For those bringing a wireless machine an additional 25 points will be awarded to them on the completion of atleast one successful throw in one of the regions.

Rules

1. The participant can reload his machine any number of times within 3 minutes.
2. If during the run the ball placed on the machine falls inside the pool then the participant will have to load another ball and start once again. The time however will not stop during this interval.
3. The zone in which the ball touches the surface of the water for the first time will be considered for the points.
4. The mechanism used for the launcher cannot be changed completely. Only a part of it can be replaced while reloading.
5. During the shot the entire body of the machine including the throwing mechanism should lie behind the shooting line till the ball is in contact with the launcher. Taking a shot from beyond the shooting line would result in cancelling of that shot and hence forfeiting the points of that shot.
6. The machine should have an on board supply of power.
7. If the ball falls on the line of any zone then the points corresponding to the previous zone will be awarded to the team.

General Rules

1. The teams must adhere to the spirit of healthy competition. The teams must not damage the opponent's machine in any way. Judges reserve the right to disqualify any team indulging in misbehaviour.
2. Any team that is not ready at the time specified will be disqualified from the competition automatically.
3. The machine would be checked for its safety before the race and would be discarded if found unsafe for other teams and spectators.
4. Decision of the judges shall be treated as final and binding on all.

Team Specification

A team must consist of 3 or less participants. Students from different educational institutes can form a team.
