" It's how the smooth take the rough."

Range Rover

Ever thought of making a ride so smooth that not even a drop spills from your drink when you pass over hurdles? Well now is your chance to start. Robotix 2012 invites you to this first-of-its-kind, unique event, where your robot needs to balance a flask of liquid and traverse through uncharted and rough terrain. Only the best can survive.. !

 

 


Build a robot that balances a vessel filled with liquid while traversing over irregular terrains. The robot has to prevent the liquid from spilling.

  1. The inner container will contain water and will be open.
  2. The outer container will be sealed with a lid before the event commences.
  3. The inner container is attached to the outer container at its base and the two containers behave as a single entity.
  4. The outer container is provided so that water spilled from the container containing water can be collected in the outer container.
  5. The outer container shown has a base diameter of 20 cm and height 25 cm.
  6. The inner container has a base diameter of 10 cm and height 20 cm.
  7. The weight of the container as a whole, without liquid, is 400 gm.
  8. The weight of the container as a whole with the inner container filled with liquid, is 2100 gm.

    WEDGE

    1. The width of the path is 0.75 m.
    2. The length of the path is 1.5 m.
    3. The slope has a maximum angle of 25 degrees.
    4. The maximum height from the ground is 42 cm.

    1. The width of the path is 50 cm.
    2. The length of the path is approximately 2 m.
    3. The height of the walls along the path is 50 cm.
    4. Turns comprise of curves of turning radius upto 90 degrees.

    1. Each team should consist of a maximum of 4 members.
    2. No two teams can have any participant common.
    3. The team members can independently be from different institutes.
    4. A professional conduct of participation is expected from the participants.
    5. The decision of team ROBOTIX will be final and binding.

    1. The robot may be powered on-board as well as off-board.
    2. All circuitry and sensory equipment should be placed on the robot adhering to the robot specifications as mentioned.
    3. Participants will have to bring their own programmers, cables and soft-wares. No programmers will be supplied.
    4. LEGO kits or its spare parts or pre-made mechanical parts are not allowed.
    5. Readymade gearboxes, sensors, development boards can be used but no other part of the robot should contain any readymade components. Simple car bases with no extra features may be used.
    6. The robot should not disorient the arena in any way. If it does so, a penalty will be imposed on the team.
    7. Any damage to the container provided to the participant would result in a penalty.

    1. A white line of 3 cm width will be provided on the arena (black) for autonomous line following robots.
    2. Participants are allowed to manually fix the container on the robot. A time of 1 minute duration would be provided for this purpose before the commencement of each run.
    3. The inner container would be refilled at the beginning of each run.
    4. Amount of water left in the inner container will be used to calculate the score which will be judged by calibrations present on the inner container.
    5. The maximum time allowed for each run will change from round to round.
    6. If the bot malfunctions the participant may ask for a "Time Out". In that case the timer will be stopped, the scoring will be done taking into account the time elapsed till then and a penalty will be imposed on the team. Maximum of 3 Time Outs are allowed for each run.
    7. At the starting of each run, the bot will be placed at the Starting line.
    8. In case the bot completely loses the trail of the track or it encounters some internal problem, the team has an option of restarting their run. A maximum of 2 restarts are allowed for the main round and a maximum of 3 restarts for the final round.
    9. All the dimensions are to be considered with a tolerance of 10% .

    1. The robot may be manual or autonomous.
    2. The base of the robot must completely fit inside a square of side 35 cm.However, there is no restriction on the maximum height of the robot. No part/mechanism of/on the robot should exceed the given dimensions before the commencement of the event run.
    3. The robot may exceed the given dimensions after the event commences.
    4. The autonomous robot should be on board processing robot, i.e., the robot cannot be controlled by a remotely kept computer.

  • Penalty for restart=500 points
  •   Penalty for timeout=250 points
  •   Points for water left in the inner tumbler will be calculated using this formula: W=(13 - x )* (12 - x)* (25 - 2x) where x = y/80 where y is the volume of liquid(measured in ml)in the outer tumbler.If liquid in outer tumbler is greater in volume than 880ml then W=0.
  • A 20% bonus will be added to the score if the robot is completely autonomous.
  • A 15% bonus will be added to the score if the navigation is manual and everything else including the balancing is autonomous.
  • T = Run Time
  • Score for a Run(S1): T1 + T2 + T3 + T4 + T5 + T6 + T7 + W - Penalty for Restarts - Penalty For Timeouts - 3 * Run Time  
  • Scoring Formula:S1 + S2 + S3
