To make a mechanically controlled robot to assemble freight cars and join them to form a train.

The arena will have freight cars in different parts of the arena containing obstacles. The robot has to guide each one of them, one at a time, and align them back to back to form a train in a specified corner of the arena. Or the robot can form a train by collecting the freights together and then reach its destination. The participating robot should be able to hook itself to the freight and guide it to the previous freight. It should have a mechanical design to hook itself with the freight. Magnets/electromagnets are not allowed onboard in any form to guide the freights.

1. The robot should be a manually controlled car with required mechanical setup to hook to freight and guide it to its destination.
2. No Lego kits or complete car bases allowed.
3. The dimension of the robot should not exceed 20 cm X 20 cm X 30 cm.
4. The robot can have multiple hooking mechanisms in it. The participant can hook the freights from any side of its robot.
5. The participant's robot should not contain magnetic material on its periphery and the hook should also be non-magnetic.

1. Freights will be made of plywood. The dimensions of the freights are indicated in the diagram below.
2. The freights will have three freewheels, two at the rear end and one in front.
3. The front face (breadth X height) of the freight cars having the hook will be magnetic in nature. This faces will help in the back to back alignment of the freights.
4. The rear face (breadth X height) of the freight cars will have metal strips attached to it.
5. The ring is U-shaped. The inner radii of the ring are 0.5cm and 1.5 cm.
6. The figure indicated below is a sample of the freight. the dotted box inside the main box indicates the hollow portion. The colored bars at the front and rear of box indicate magnets. The ring shown in the sample may change.
7. The hook is located 60mm above ground (including wheels).
8. The maximum weight of the freight is 370g (empty freight).

1. The participant cannot push or pull the freight without hooking it. He/She may push the freight in the destination area while forming train. Besides this, if the freight is moved without hooking intentionally, then the participant has to undergo restart penalty.
2. There will be three freights in the initial stages of elimination or preliminary round in each half of the arena. The Q/F, S/F, Finals match will be one on one matches. There will be eight freights, four in each half, out of which two sets of three freights will have priority number on them which will be assigned to each team. The rest two freights will be common to both teams, so the team with maximum freights attached or best time wins.
3. The freights should be aligned according to their preference no. mentioned in a definite manner on the top of the cart to the magnetic part of the arena. Lowest number indicates highest priority and has to be hooked last while forming the train; similarly lowest priority freight is to be attached first and directly to the magnetic wall. This rule is valid for all the rounds including preliminary rounds.
4. In the Q/F, S/F and finals, the bot has to first complete the train consisting of the freights with the priority order mentioned on them and attach it to the magnetic wall in the same order as mentioned above (that is freight with lowest priority attached to the wall and one with the highest priority attached last). Only then can is it free to go and tow the fourth freight which has to be attached to the existing train. In doing so the bot cannot disturb the position of any other freight.
5. In the preliminary rounds, the bot can move only in one part of the arena. If the bot does wander off into the other half, it will be penalised an extra 30 seconds. In subsequent rounds, the bot can go to the other half only if it has completed towing and forming the train with freights on its side.
6. If in the game, freight gets toppled due to participant’s fault of controlling the robot, either he can restart the game for that freight from its initial position or if the robot has the capability of restoring the freight's orientation, the participant can continue from that position. In case of robot having the capability of restoring, there won't be any penalty but the stopwatch will continue its operation during these activities. But in case of restart, restart penalty factor will come into play. Restart penalty factor is discussed in scoring section.
7. The freights will be loaded with weights in the subsequent matches after preliminary round. The details of the weight will be notified shortly.
8. Following of priority in attaching the freights is most important. Not following the order may result in awarding one fourth of the points for each wrong freight.
9. A maximum of two restarts is allowed. Each time a restart penalty factor will come into consideration as discussed in scoring section.
10. The wire should remain slack all the time during the event. Any objection by the inspector of the game will lead to a penalty of a factor corresponding to 30 seconds, with disqualification on the third warning. This is on the discretion of the inspector and cannot be challenged.
11. The robots participating should not have any part which is magnetic in nature. This means the robot has to hook up the freights and their magnet cannot be used to stick it to the participating robot.
12. Test run for the robots is only allowed before the commencement of the events and between the event rounds.
13. The participant team is required to bring their extension cord and multipoint plug. We will provide power point with 220 V 50 Hz supply.
14. The Robotix Team is not responsible for any power cut during the commencement of the round, and the participant needs to start off fresh.
15. The details for the final rounds will be declared at the time of event only.
16. Arena and freight specification will remain same for all the rounds.

1. The maximum time of a game is 7 min.
2. Scoring will be done according to the following system in the preliminary round :
   1. Time efficiency (t) = [(420 – time in seconds)/10]
   2. Restart penalty factor(p) = [(no of restarts)*(30 seconds)/10]
   3. Freight Bonus Points(g) = [4(1^st freight completed)+ 6(2^nd freight completed)+ 8(3^rd freight completed)].
   4. Final Score = t + g - p
3. Scoring will be done according to the following system in the Subsequent rounds :
   1. Time efficiency (t) = [(420 – time in seconds)/10]
   2. Restart penalty factor(p) = [(no of restarts)*(30 seconds)/10]
   3. Freight Bonus Points(g) = [4(1^st freight completed) + 6(2^nd freight completed) + 8(3^rd freight completed) + 10(4^th freight completed) + 12(5^th freight completed)].
   4. Final Score = t + g - p
4. After preliminary round, 16 teams will be qualified for the next round, and so on.

1. Each team can consist of a maximum of 4 members.
2. The team members can be from different institutes or colleges.
3. The right spirit of participation is expected form the participants.
4. The decision of the ROBOTIX team will be final and binding.
