Event Introduction

The classic Robot Wars comes to Engineer, but with a twist. Can you build the most cruel opponent cruncher, using only wooden parts? This time at Engineer, that’s what we want you to do! TIMBER!!!

Event Format

The event will be held over 2 rounds

The first round is an elimination round. This round is a point based round. Bots should push weights off the arena to qualify for the next round.

The second round is the one-on-one fight! The second round will be a knockout tournament.

Rules and Regulations

1. This is a point based round.

2. Bots should push off the arena as many weights as possible in a fixed time of 4 min.

3. Each team gets 2 trials. The best of 2 trials is considered as the points scored.

4. The points gained by pushing heavier weights, progressively increases.

5. A new weight will be added to the arena only when the previous weight has been successfully pushed off the arena.

6. Once a weight is pushed off the arena, the next weight will be placed at the middle of the arena.

7. The mass of the weights are: 750gm, 1kg, 2kg, 3kg

8. The point scoring system is:

Points scored = ((Total weight pushed off the arena in Kg) * 10.)/(time taken to push of all weights in minutes)

9. The teams can choose the order in which they want to push the weights. The default order of weights is 750gm, 1kg, 2kg and 3kg.

10. Teams can also opt to push a combination of weights off the arena in a single trial.

a. for eg: a team may choose to push the weights in the following order: 3 kg and 3.75kg or they can also choose to push 6.75 kg in a single trial

11. The dimensions of the weight box is 15 cm x 15 cm x 15 cm.

12. If a team opts for a combination of weights, the combination will be placed in the box itself.

13. Each weight can be pushed off the arena only ONCE.

14. The total points scored in this round is used as a basis to qualify teams to the second round.
