IRC SCHOOL LEAGUE: SEASON 9
MIDDLE LEVEL PROBLEM STATEMENT


Problem Statement

To build one Autonomous and two Manual Robots that can carry out the task of diffusing and disposing Mines placed by the enemies in domestic waters.

Problem Description

A navy or maritime force is a fleet of waterborne military vessels (watercraft) and its associated naval aviation, both sea-based and land-based. It is the branch of a nation's armed forces principally designated for naval and amphibious warfare: namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions.

Bot Information

Your team will be tasked to develop an autonomous (Bot: Seeker) and two remote-controlled Robots that can detect naval mines {placed by the enemies} (Bot: Diffuser). On detection, these mines need to be taken away to a dispose location (Bot: Disposer).

All three robots can run simultaneously.

Seeker
Seeker is first, an autonomous bot, that has been tasked to detect naval mines placed in its path and give a signal (by some sort of indication/mechanism attached with robot) to Diffuser and Disposer robot. The base of the robot should not exceed the size 21 cm x 21 cm.

Diffuser
Diffuser is second, a remote-controlled bot, that has been tasked to ensure that on the signal of Seeker it has to diffuse the mine, by picking it up from its location and pass it to Disposer. The base of the robot should not exceed the size 21 cm x 21 cm.

Disposer
Disposer is third, a remote-controlled bot, essentially a rope car robot that has been tasked to ensure that the diffused mine dropped in its carriage is disposed off at the designated location. The dimension of the robot should not exceed the size 21 cm x 21 cm x 21 cm.(In its smallest convertible form).
Note: The above mechanisms are mostly suggestive, you can choose to create a design that you deem fit. However, the robot should be able to fit inside the verification prop of the size 21 cm x 21 cm x 6.5 cm (Seeker and Diffuser) and 21 cm x 21 cm x 21 cm (Disposer). Please see this section for more details.
Tip: Try to keep the weight of the Robot as light as possible as a heavy robot will be slower on the Trail and also consider the props dimensions tolerance of 5% while designing.

Other Information

Life during the Run:
Seeker is equipped with 4 lives for the entire duration of the run. After that Seeker will be taken off and rest 2 Bots can continue with their tasks.

Detection of Mines:
Mines placed on arena are basically vertical structures that need to be detected by the Seeker bot. Seeker bot needs to make sure that it detects them without touching. Touching the mine would be considered as loss of life.

Deviation of Seeker:
Seeker needs to always follow the line path. At any point, if it deviates from the line this will be considered as a loss of life and Seeker will have to start its run from beginning(Start Area 1) (No time will be paused in this scenario). Deviation of the robot will be considered when it comes out of the white area which is around the Blackline.

Arena

  • The length & width of the arena is 10 feet x 6 feet.
  • The Arena is placed on the ground within a frame boundary on the Yellow-Black line (made out of EVA sheet).
  • All the props are described in detail next to the arena design.

Arena Tasks

Tasks of Seeker:
  • Seeker will start from Start Area 1.
  • Seeker has to follow the black line and search for all five designated areas for mines on the black line and reach at End area a to complete the run.
  • When mine is detected, it has to give signal in the form of mechanism attached with the robot, “that it has detected a naval mine”, to the diffuser. [This need to happen each time a mine is detected and this indication should stop as soon as the mine is taken by Diffuser].

Tasks of Diffuser:
  • Diffuser needs to wait for the signal from Seeker. Once seeker gets the signal, it needs to reach the target area and diffuse the mine by picking up the naval mine and pass it to Disposer at Start Area 3.

Tasks of Disposer:
  • Disposer also needs to wait for the signal from Seeker. Once seeker gives the signal, it needs to collect the naval mine from the diffuser at its start area 3 only(Mine should not be touching the ground).
  • Once it has the naval mine, it needs to travel to the disposer end and drop it disposing container in designed area.

Note: If in any condition Mine is not disposed properly (inside designated area) then it will be kept back to Start Area 3 and Diffuser will pass it again to disposer. Score will be awarded only once.

Scoring

Mine 1:
Seeker is successfully able to detect first naval mine

Note: This task will be considered complete when Seeker stops just before the naval mine and signal the diffuser and disposer. If seeker touches the mine then it will be considered as a loss of 1 life. Also, there will be no score awarded if there is no indication from Seeker.

Middle Level Rules and Regulations

  • Before the arena run team, needs to show the indication mechanism to referee.
  • Indication is a process which shows us the detection of mine and it should be there only when mine is in front of the robot. Overruling this can fetch you no points for detection of mine.
  • Also, this indication should stop once the mine has been picked up by the diffuser. If indication continues even after mine has been picked up or before reaching the mine, it will be considered as loss of life.
  • The duration of the run will be 6 minutes and there won't be any trial time provided for the run on the event day.
  • If disposer drops the mine outside drop area, referee will keep mine at Start Area 3 and diffuser need to pick it again (For every task scores will be awarded only once).
  • When Disposer has dropped or placed the mine in container i.e. drop area, Referee will take out that mine from the container and keep it outside.
  • Only Avishkaar kits are allowed to build these robots.
  • A power source of 7.4 Volts and 2200 MAH current is allowed in the bots.
  • Participants can touch the robots only when they are in the start areas and nowhere else.
  • Participant can repair their robots only at the start area in case of any problem or damage to the robot. However, the timer will not stop during this repair..
  • If any of the robot goes out of the arena, the referee would bring it back to the respective Start Area and the arena props (if they were attached to the robot in some manner) to their respective start locations and no points would be awarded for them.
  • If a team is able to finish all its tasks before time, all the props will be refurbished on the arena and the team can start scoring points again. The timer would stop when the refurbishing is taking place.
  • If any student touches any of the props intentionally/unintentionally, it will be considered as a loss of life.
  • If seeker touches the mine then it will be considered as a loss of 1 life.
  • During the Arena run if by any means the Arena/Props got damaged then referee can disqualify the team.
  • Participants can call for a Loss of Life at any time if they found any dead end in the run and robots will start again from the Start areas.

Interpretation

  • Problem statement text means exactly and only what it says, so take it literally whenever possible.
  • Do not interpret text based on your assumption about intent, or on how a situation might be in “real life”.
  • If a detail isn’t mentioned, then it doesn’t matter.
  • There are no hidden requirements or restrictions. If you’ve read everything, then you know everything.

Examples

  • If a task requirement is to collect the prop, it means the prop should be in control and attached with the robot.
  • If a mission requirement is to place the prop at the designated location, it means the prop should be completely inside the designed area. Points will not be awarded if it is partially inside or on the line.
  • You’re encouraged to think this way - Please learn the requirements and constraints very well, tasks needs to be done as explained in the task description only.

Variability

As you build and program, keep in mind that our suppliers, mentors, and volunteers try very hard to make all arena correct and identical, but you should always expect some variability (i.e. tolerance of 5%), such as:

  • Flaws in the arrangement of border walls i.e. boundary mats.
  • Variety in lighting conditions, from hour to hour, and/or arena to arena.
  • Texture/bumps under the mat, due to imperfections, seams, or props.
  • Presence or absence of tape at the edges of the Arena/Props.
  • Waviness in the arena - at many competitions, it’s impossible for the arena to be rolled out in time to lose their waviness. Location and severity of waviness varies.
  • Two important building techniques you can use to limit the effects of variability are:

    1. Use Caster wheels while building your Robot to avoid bumps in Arena.
    2. Cover your sensors from surrounding light.

The Scoring Process

  • END-OF-MATCH SCORING - Most of your score depends on the conditions at the exact time the match ends.
  • The Arena/Props is the evidence of most of your score. When the run ends, PLEASE DON’T TOUCH ANYTHING! The referee first needs time to record the condition of the arena on a score sheet and come to agreement with you (students only) about what points were scored or missed and why.
  • Points are not given to the particular task, which is destroyed at the end.
  • If you agree with the score, you will have to sign the scoring sheet, and the scores will be final.
  • If you don’t agree, tell the referee politely. If the referee has missed out something and it is brought to their notice, they will consider the same.
  • After a short discussion, if the referee is not sure about the score, the head referee makes the final decision.
  • MID-MATCH SCORING - Sometimes part of your score is permanently determined during the match instead of at the end.

    - EXAMPLE: When a mission is required to be achieved through a specific method, but is achieved by some other method, it is marked scoreless. Please don’t try to show video to the referees.
    - EXAMPLE: If the robot puts Model A into a scoring condition by destroying Model B, the Model B mission is marked scoreless.
    - EXAMPLE: If the robot is required to drive over something in the middle of the match, the referee will mark the score for that when it happens, since no lingering evidence will be visible.

Verification of Robots

Note: The design shown in image is a graphical image and no design reference must be drawn from this. For your design, please refer to the exact size details of the verification prop.
Note: Bot should sit comfortably on the floor while verification. Any part of the bot in air would be liable for rejection.
