GAME DESCRIPTION

The robots participating in the competition must remove the trash from a place and reach the destination by decoding the bits drawn in the path. Trash of weight less than 50 gm will be placed in the start zone and the robot must remove the trash and start to decode the path. Robots will be allowed to pass from a dark box with one door open. Robot should get out of the box with door open. Robot reaching to end zone with maximum points will be considered as a winner.

Two robots are allowed to operate in two identical platforms. The robot should complete the objectives listed below.

Objectives

STAGE I: Robot should find and remove the trash kept in a platform and start to decode the path.
STAGE II: Bit patterns are drawn in the track to indicate the direction. A bit is represented by a white or a black box drawn in the path. Robot should decode bit pattern and move accordingly. Also, Robot need to indicate the bit pattern by the LED. (For example, when it detects black the LED should glow.)
STAGE III: The robot is allowed to enter the cave. There are two doors in the cave. Robots are allowed to pass from a door which will be closed after the robot enters the cave. Robot should come out of the cave from a door which is open. (following the light passing from the door is recommended)
STAGE IV: The robot should enter in the end zone and drop the gem in the end zone.

Judging Criteria

Robot must remove the trash and reach to the end zone decoding the bit patterns and passing through the cave.

• The robot is allowed to start over from the nearest check point if the robot goes out of the track.
• The robot should indicate the bit patterns.
• Game is based on the pointing system as follows:
• • • Removing the trash adds 25 points to the team.
  • If the robot completes the task faster than the opponent, 50 points will be added.
  • The operator can skip the trash and continue without if the attempt of removing the trash fails within 60 seconds.
  • Correct Bit pattern indication adds 15 points to the team whereas deduce 20 points if failed to do so.
  • Skipping the Checkpoint deduces 25
  • Getting out from the cave adds 25
  • Robot can skip the cave, but skipping the cave deduces 25

Specifications

A. Robot

• One robot per team of 4 members.
• On board power supply must be used.
• The minimum length and width of bot is 10 cm×10 cm×10 cm and maximum should be determined according to the dimensions of platform.
• The robot should have 4 Led at the top to indicate the 4-bit pattern.

B. Platform

• B.1 GEM ZONE
• • The diameter of Trash Zone is 100 cm
  • It has white background with black border of 2.5 cm width.
  • It has a movable arc which is black in color which connects Gem Zone to path.
  • When obstacle is picked by robot, the arc opens and connects Gem Zone to path with continuous white background.

  • B.2 Path
  • • The width of path is 30 cm including black border of 2.5 cm each in both sides
    • It contains 4 patterns indicating 4 bits.
    • The first two bits are variable and next two bits indicate the direction of path.
    • All bits are at different distance from the wall of height 40 cm and width 35 cm present opposite to the path where direction is needed.
    • When 3rd bit is 1 and 4th is 0, The bot should turn Left and when 3rd is 0 and 4th is 1 it should turn Right. i.e. When B3=1 and B4=0: Turn Left When B3=0 and B4=1: Turn Right

    • B.2 End Zone
    • • The end zone is indicated by a rectangle in a path with black in color and at a distance of 30 cm from the wall opposite to the end zone. The end zone is equivalent to last two black bits.

      • B.2 Trash
      • • Trash is a cube of dimension 15cm*15cm*15cm (l*b*h).
        • The weight of trash is not more than 50g.
        • The color of trash is White in color.

        • Checkpoint
        • • Each stage has at least a checkpoint and will be notified before the game.
          • B.2 Gem
          • • The minimum dimension of Cave is 100 cm×100 cm×60 cm (l×b×h).
            • The cave has two doors one is entrance and another is exit door.
            • Entrance door will be closed as the robot goes inside the cave.
            • The light is allowed to pass into the cave from the exit game so that the robot can track the light and get out of the cave (Tracking the light is not compulsory).

            • Robot should complete all the objectives specified.
            • Robot should cross a checkpoint within 3 attempts. Unable to do so, Robot must skip the checkpoint. However, Robot can skip upon the decision of team leader.
            • Robot should not destroy any part of the platform.
            • Judge’s decision is considered final decision.
            • Only one member from a team can operate the robot.
            • Robot verification must be done before every game.
            Note

            • The platform may be drawn either in Flex (As in Figure 9 except Cave, Gem and Wall) or may be made by Plywood (As in Figure 8) and will be notified before 3 weeks of Game.
