1. Multiple robots are allowed.
2. Each robot should be a manually controlled vehicle with at least one robot having the required mechanism to pick up and hold the blocks and place them at the appropriate positions.
3. The dimensions of the robot (in case of only one bot) should not exceed 35 cm (l) * 35 cm (b) * 50 cm (h). If the participant is using more than one robot, then the initial orientation of all the robots at the time of the start should fit completely within the prescribed dimensions and once all the robots have been placed in this orientation, no manual contact with them is allowed.
4. The robot should be remotely controlled and the connections (the wires, for instance) between the control unit and the robot should be slag at all times.
   
5. No lego kits or complete car bases are allowed.

1. The arena is a simple 5m * 2m polished plywood base enclosed by a boundary wall (height 10 cm).
2. The arena will be divided into two parts each of 2.5m * 2m. Every participant has to operate her/his bot(s) in her/his part of the arena.
3. The blocks will be placed within a demarcated region of the arena. [Zone B]
4. A 50 cm * 50 cm region would be marked in the arena. This would be the starting area of the robot(s). [Zone A]
5. The arena will be marked with another 50 cm * 50 cm square where the structure has to be built. Within this square, there would be pre-specified demarcations for placing the blocks. [Zone C]

Blocks of the following specified dimensions would be used in the first three rounds. However their dimensions may vary by 10% of the mentioned values.

1. Cuboid of sides 13cm * 3cm* 10cm. (l*b*h) Weight: Less than 120 gms.
2. Sphere of diameter 7 cm . Weight: Less than 150 gms.
3. Disk of diameter 17 cm with a thickness of 0.6 cm. The disk would have a cylindrical protrusion of diameter 2.5 cm and height 9 cm, coming out from its centre. Weight: Less than 190 gms.
4. Cylinder of internal diameter 4.8 cm, external diameter 6 cm and height 10cm. Weight: Less than 90 gms.

Round 1:

The sphere has to be placed in between the two cuboids as shown in the figure below.

For this structure to be built, the following boundaries would be present in zone C.

The cuboids must completely lie in the demarcated area and must not be placed over the boundaries. The contact point of the sphere may lie anywhere on the circular patch as shown.

Round 2:

A sphere has to be kept between two cuboids and a disc over this structure. The disc has cylindrical protrusion at its centre for the ease of gripping.

For this structure to be built, the following boundaries would be present in zone C.


The sphere may lie anywhere between in the two cuboids and the disc has to be supported on the cuboids as shown, but it need not be located exactly symmetrically.

Round 3

A cylinder with a cylindrical cavity of internal diameter 1.3 cm larger than the diameter of the protrusion of the disc has to be placed over the disc. For this structure to be built, the boundaries present in zone C would be same as those for round 2.
A detailed view of the cylinder is shown below.

1. The robot(s) has/have to make a start from the Zone A. If there are more than one robot, then their initial orientation in the starting square should fit in the specified dimensions and no physical contact with the robots is allowed once they are placed in the arena.
2. The bot(s) has/have to pick up the blocks from zone B and place them in the required configuration in zone C.
3. The structure to be constructed for rounds one, two and three are provided. The structures for subsequent rounds would be provided at the time of the event.
4. The position for placing each block in zone C would be marked with boundaries made of white paper strips, stuck on the arena. There would be some relief space given inside the boundaries. For example, to place a block of dimension 13cm (l) * 3cm(b), the area inside the corresponding boundary would be, say, 15cm(l)*5cm(b). A block which touches the white boundary line will be awarded only half of the block-points for that block, hence the block must be placed completely within the boundaries.
5. Sliding of block on the arena is allowed.
   
6. Blocks would be numbered. However, they can be arranged in any order.
7. Time Out: In case a team wants to restart with a block (for example in a case when a block falls down in the midway or if a block topples down during arranging), the team can ask for a time-out. They can do so by calling out the corresponding block number and then 'Time Out' (for example: Block no 2 Time Out). Then the timer would be paused and this particular block would be placed at its initial position in the zone B. After the time-out, the robots would resume from their previous positions and the time would continue from where it was paused.
8. In case a team wants to restart with more than one block, the participant has to call out the number of all those blocks before calling out 'Time Out'. This will be counted as a single timeout.
9. Number of time-outs would be restricted to 1, 2 and 3 in the first, the second and the third rounds respectively for each team.
10. Touching a block on the arena, even during a time-out, would straightaway disqualify the team.
11. The maximum permitted time for the first, the second and the third rounds are 6, 7 and 10 minutes respectively.
12. If a robot gets into the other half of the arena (the other participant's half of the arena), it'll be awarded with a penalty of 10% of the final score, each time it does that.
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 rules are subject to minor changes.
15. Each team can consist of a maximum of 4 members.
16. The team members can be from different institutes or colleges.
17. Each team should have unique participants i.e. no two teams can have even a single participant in common.
18. The decision of the ROBOTIX team will be final and binding.

1. To qualify for the second round, the task in the first round has to be completed fully, without any errors. Moving on to the second round will be completely time dependent.
2. Second round onwards, the score would be given by :
   
   10*(sum of points corresponding to the correctly placed blocks) – (time taken in seconds) – (number of time-outs taken)*30
   
   


3. The time taken will be counted till the task of the particular round is completed.
4. Specific points would be awarded for correct placement of each individual block. These points would be updated soon.
5. Qualification for third and further rounds shall depend on the score. In case, any two teams have the same score, the team completing the task in lesser amount of time shall be given preference.
