Build a manually controlled robot capable of traversing a broken pipe and repairing it on the way, in this case, popping corks plugged in the pipe.

  • Traverse a broken pipe (helix) with the help of a central rod.
  • Cross the checkpoints (green colored flags) marked in the helix while avoiding certain forbidden areas (red colored flags).
  • Pop out the corks plugged in the holes.

Arena Components:

 

Helix Specifications:

  • Span of the helix (Outer main Pipe) would be 220 degrees.
  • The diameter of the helix will be 60 cms.
  • The Helix will be divided into multiple sections, each of length 1 m.
  • The first round has 3 sections, while the second round has 4 sections.
  • The Helix also has an inner concentric rod running all through its length which can be used for traversal.

 

Inner Rod:

  • A metal (subject to change) rod which can be used while traversal, would be present at the center of the helix.
  • The diameter of the rod will be 9 cms.
  • Stands supporting this rod on either end are detachable to enable the insertion of the robot around the rod.


Helix and Inner Rod

 

Checkpoints:

  • These will be indicated by green flags of height 8 cm and width 4 cm.
  • In the first round, there will be 6 checkpoints.
  • In the second round, there will be 8 checkpoints.


 

Checkpoint

 

Forbidden Areas:

  • These will be indicated by red flags of height 8 cm and width 4 cm.
  • There are no forbidden zones in the first round.
  • There are 4 forbidden zones in second round.


Forbidden Area

 

Crossing A Checkpoint/ Forbidden Area:

A checkpoint/forbidden area is said to be crossed when it is completely folded as shown in the picture below. This checkpoint/forbidden area will fold completely on the exertion of a slight pushing force by the robot as it is spring loaded.

Cork:

  • Wooden cork pieces of diameter 4 cm and height 2 cm would be present in the arena.
  • A simple pushing/popping mechanism can be used for popping the corks.
  • A cork is said to be pushed when none of its portion is in contact with the broken pipe (helix)

Round 1:


Round 1: Side view


Round 1: Axial view

 

Arena Description:

  • The arena would consist of 3 sections each of length 1 m.
  • There would be a total of 6 checkpoints in the arena, 2 in each section.
  • There would be 3 corks present in the arena, 1 in each section.

     

Task:

  • The robot has to traverse the helix (all the 3 sections) while crossing over the checkpoints and pushing the corks off the plugs.

 

Round Rules:

  • Maximum Time alloted- 3 minutes
  • Number of Sections- 3
  • Number of Checkpoints- 6
  • Number of Corks- 3
  • Maximum Timeouts allowed - 2 (1 min each)
  • Maximum number Restarts allowed - 1

 

Scoring :

  • Crossing the Checkpoint - 100 points
  • Popping the corks-150 points
  • Time bonus - Time left (in seconds)
  • Timeout - Penalty of 50 points
  • Restart - Penalty of 100 points
  • Robot falls off the arena (helix or central rod) - Penalty of 100 points

 

Scoring Formula :    100 * (No. of checkpoints crossed) + 150 * (Number of corks Popped) + TimeBonus - 50 * (Number of timeouts) - 100 * (Restart) -  100 * (No. of times robot falls off the arena)

Round 2:


Round 2: Side View

 

Round 2: Axial View


 

Arena Description:

  • The arena would consist of 4 sections each of length 1 m.
  • There would be a total of 8 checkpoints in the arena, 2 in each section.
  • There would be 4 forbidden areas across the helix, 1 in each section.
  • There would be 4 corks present in the arena, 1 in each section.

 

Task:

  • The robot has to traverse the complete helix while crossing over the checkpoints and avoiding the forbidden areas.
  • The robot has to pop the corks by pushing them out of the holes present in the helix.

Round Rules:

  • Maximum Time Alloted - 4 minutes
  • Number of Sections - 4
  • Number of Checkpoints - 8
  • Number of Forbidden Areas - 4
  • Number of Corks - 4
  • Maximum Time-outs allowed - 2 (1 min each)
  • Maximum Restarts allowed - 1

 

Scoring Formula:

  • Crossing the Checkpoint - 100 points
  • Popping the corks - 150 points
  • Time bonus - Time left (in seconds)
  • Crossing the Forbidden area - Penalty of 75 points
  • Timeout - Penalty of 50 points
  • Restart - Penalty of 100 points
  • Robot falls off the arena (helix or central rod) - Penalty of 100 points


Scoring Formula :    100 * (No. of checkpoints crossed) + 150 * (Number of corks Popped) + TimeBonus - 75 * (Number of Forbidden areas crossed) - 50 * (Number of timeouts) - 100 * (Restart) -  100 * (No. of times robot falls off the arena)

3-D Arena

Round Three

  • The task and arena of the third round will be disclosed at the time of the event.
  • However, no extra mechanisms will be required on the part of the robot.

General Rules:

  • The maximum number of participants allowed per team: 4 people.
  • The participants will be provided with 220 Volts, 50 Hz standard AC supply.
  • Participants will have to themselves arrange for any other power supply required for their robot.
  • Teams qualifying the first round will go into the second round and those qualifying the second round participate in the third round.
  • Teams cannot tinker with their bots during the run.
  • LEGO kits or its spare parts or pre-made mechanical parts are not allowed. (http://en.wikipedia.org/wiki/Lego_Mindstorms)
  • The decision of the Team Robotix will be final and binding.
  • The rules are subject to change.

Event Rules:

  • The robot will start the run from the start zone.
  • The robot is free to use either the central rod or the helix or a combination of both for traversal.
  • Participants will be allowed to manually clasp the robot to the rod at the starting zone before the start of the run. 
  • In the first round, the robot will traverse the helix from one end to the other running over the green flags(checkpoints) and popping the corks by pushing them out of the holes.
  • In the second round, the robot has to traverse the arena from one end to the other avoiding the forbidden zones, running over the green checkpoints and popping the corks out of the holes.
  • Points will be awarded for popping the corks.
  • Points will be awarded for crossing the checkpoints.
  • Points will be deducted for running over (defined in the same way as crossing a checkpoint) the red flags (or forbidden zones).

 

Robot Specifications:

  • Robot should fit into a box of dimensions 65*50*50 cm3. No part/mechanism of/on the bot should exceed the given dimensions at the  commencement of the event. However the dimensions can change during the course of the run.
  • Dimensions of the arena are to be considered with a maximum tolerance of 10 %. However the robot should strictly adhere to the mentioned dimensions.

SCORING:

  • 100 points -Crossing the Checkpoint
  • 150 points - Pushing the corks off the holes
  • Time Bonus - Time left in seconds

 

PENALTY:

  • -75 points - Crossing the forbidden area
  • -50 points -  per Timeout
  • -100 points - per Restart
  • -100 points - Robot falling off the arena (Helix or Central rod)

The helix, more commonly called the spiral, is a beautiful thing. With its majestic symmetry and fluidity, it can ignite the imagination of those who appreciate it. And for the robotics enthusiast, there would be something distinctly enthralling in the design, creation and control of a robot that could actually traverse a helix smoothly and effectively. InspiralOn, a manual event of ROBOTIX 2014, looks to bring out that excitement in its participants, whose robots have to move along the spiral structure, making repairs where they are required, and with only a central rod for assistance. The spiral is ready. Are you?
