How to do an AWS Draw

Post by James »

Posting this so that anyone that is interested/planning on running an event can see the tried and tested method of doing the draw that is used at the AWS. (and most other events)

Before the event (usually the night before) print off a list of the robots that are signed up before the event and cut them up so each robot has its own slip. if any robots do not arrive, or you have extra robots on the day that weren't signed up before then just hand write them on a piece of paper and add them in.

Then when you want to do the draw sort the slips into teams and robot that you actually have, you should have something that looks a bit like this:

(i'm going to do 16 robots as an example but this works for however many robots/teams you have )
(letters are same team, numbers are robots in that team)

Code: Select all

A1    B1    C1    D1    E1    F1    G1
A2    B2    C2    D2    E2
A3    B3    C3
A4
now decide how many ( 2, 4 or 8 ) and which size groups ( 4-16 ) you are going to use
(i'm using 4 groups of 4) (best to use more smaller groups, so 8 groups of 8 instead of 4 groups of 16 is easier to work with)

starting with the teams with 4 robots put one robot from each 4-robot team in to a hat (or box) and pick one out randomly
(i'm going to pick A as it's the only team with 4 robots in this example)

you now need to give each robot in the team you just picked out a group, either by getting the person standing nearest to you but not involved in the draw (or by using a random number generator) to pick a number representing a group

The first robot from the team (the one you picked out of the box) then goes into this group

If the number picked is 1 then robot A1 goes into group1

Code: Select all

Group1    Group2    Group3    Group4
A1
then repeat for the other robots in this team
(making sure you do not put two robots from one team in the same group)

so you end up with one pile of names for each group:

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
now repeat for the 3-robot teams
(B and C)

(I picked B1 out of the hat so I do team B first)

randomly put each robot in that team in a group

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
          B1        B3        B2
then repeat for other 3-robot teams until they are all done
(making sure you have no more robots than spaces in each group)

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
C1        B1        B3        B2
          C2                  C3
same again for 2-robot teams(D and E)

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
C1        B1        B3        B2
D1       C2                  C3
          D2
now group 2 is full so do not put any more robots into that group
(sometimes you do have to move robots around if you are going to end up with two robots from one team in the same group, just be careful not to put two robots from the same team in the same group)

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
C1        B1        B3        B2
D1        C2        E1        C3
          D2                  E2
now put all the single-robot teams into the hat and draw out randomly and fill up the gaps to fill each group

Code: Select all

Group1    Group2    Group3    Group4
A1        A3        A4        A2
C1        B1        B3        B2
D1        C2        E1        C3
G1        D2        F1        E2
once you have the 4 separate groups put all robots in group 1 into the hat and draw out to determine who is fighting who

Group1
A1 Vs G1
D1 Vs C1

write these fights onto the sheets or type into Antlog and then draw the other groups in the same way

Group2
B1 Vs D2
A3 Vs C2

Group3
A4 Vs B3
E1 Vs F1

Group4
A2 Vs B2
C3 Vs E2

And you have a draw that doesn't have any robots fighting other robots in their own team :)

Often the draw is done during the lunch break or while someone else is finishing off the warm up (non-spinner) as it saves some time, but it only takes about 30 mins to do the draw for 60+ robots

It is sometimes easier to have as few people as possible involved in the draw as with any more than 2/3 people it just gets too confusing as there are too many people trying to all do different things at once and something will probably end up going wrong

If you need the double-elimination sheets or a copy of the Antlog spreadsheet they are downloadable from this thread(latest version will be at the end)
