This document outlines the structure and rules for a robotics competition with three stages: prelims, knockout, and showdown. In the prelims, robots must shoot balls through rings of different diameters within a time limit to score points. In the knockout, robots must knock blocks and pigs off a structure within a time limit by shooting balls to advance to the showdown. The showdown challenges robots to remove all pigs from a structure while saving eggs within a time limit for the highest ranking. Robots are subject to size, power, weight and operation restrictions and teams may have up to four members.

7. knockout
Game field and objects
1) Game field consists of a rectangular shooting zone and a structure in front of it.
2) Game structure is bounded by two thin transparent walls separated by a distance of 300mm.
3) Structure is placed at a distance of 800mm from the manual robot shooting zone , height of structure
is 100cm. Breadth of structure is 110mm.
4) Structure consists of two kind of blocks:
-Brown block : it represents wood and is lighter.
-Grey block : it represents stone and is heavier.

the structure.

8. Gameplay
2)ROBOT must shoot constrained to the shooting zone only.
2) Each team will be given 5 minutes to shoot 15 balls .
3) Only one ball is to be projected at one time.
4) Objective of the game is to kill all the pigs using given number of balls.
5) Pigs will be considered dead once they fall off from the structure.
6) Points will be awarded for 1) killing each pig 2) for each block that falls down and 3)
for each unused ball from the given 15 balls if you have completed the game objective.
-10 points for each brown block.
-20 points for each grey block.
-100 points for killing each pig.
-50 points for each unused ball only if a team has completed the objective.

9. 7) Game will be considered to be END when all the pigs are killed.
8) Top FIVE teams will be selected for the final showdown on following basis :
-Teams completing the given objective (i.e. to kill all the pigs) will be given first priority.
-For teams with a tie on above criteria, ranking will be decided on basis of total points
scored.
-For teams having a tie with above two criteria, ranking will be decided on the basis of
time taken for killing the last pig. The team having lesser time will be given higher
ranking.
-If teams completing the given objective is less than 5, then remaining teams will be
selected on the basis of total points scored.
