New ROBO-ONE Weight Classifications May Change The Competition

The entry window for ROBO-ONE 11 closed a few days ago, so we decided to take a close look at the field to get a feel for how the competition is likely to play out. In total, there were 186 official entries. If this competition follows along the same lines as the previous events, quite a few - somewhere between 10 to 30 percent - of them will either drop out before the morning of first day (March 24th), or will fail to pass the preliminary screening test.

That will leave us with somewhere around 150 robots challenging the initial two minute demonstration judging. Needless to say, it's going to be a long, grueling, yet very exciting day. Out of all those entries, only the top 32 will earn the right to return the following day to fight in the ring. And, to make things even more challenging, this year the winners of some other robot competitions, like Robo-Fight in Osaka and the Wonderful Robot Carnival in Tokyo, have earned a pre-qualification right, so there will be less than 32 slots left for the other robots to contend for.

And, this time around, the ROBO-ONE organizing committee has combined the ROBO-ONE J class into the regular competition, and split the entries into different weight classifications. Of course the actual number of robots that battle on the final day in each classification is hard to predict at this point, but at least we can analyze the characteristics of the unscreened entries.

It's important to understand that the ROBO-ONE entry database depends on the 'honor system' and isn't the official, audited record. The weights, heights, and track records for each robot shown in the database at this point were entered by the teams themselves.  So, there are a few obvious, unintended mistakes in the data. For example, a few of the robot weights and/or heights are shown as '0'. Of course, the robots will be officially weighed and measured when they check in the morning of the first day.

Setting aside the 10 entries with 0 height and/or weight, the height versus weight distribution for the robots looks like this:


One robot's entry shows a height of 90 cm, and weighs 11 kg.! We're not sure if this was a mistake, or if this monster will actual put in an appearance. It will definitely be impressive, if it does. There are 26 robots weighing 3 kg and over; 144 that are equal to or greater than 1 kg, but less than 3 kg; and 6 that are under 1 kg.

While we definitely applaud and support the new weight classes, in someways they will be a little disappointing. For example, we've been looking forward to watching OniMaru go head to head with King Kizer for a long time. But, since OniMaru tips the scales at over 5 kg, and King Kizer just squeezes in under the 3 kg. cutoff, it looks like they won't have the opportunity to fight each other - at least not as a part of the ROBO-ONE battles.

  1. Since they are taking the top 16 in each weight class, that’s roughly 10% of the lighter weight class and 60% of the heavier class. From this we can predict the following:

    1) Some builders will be adding weights to their robots to get them just over the weight limit, since it will be so much easier to qualify for the fighting that way.

    2) Assuming they keep the same cutoffs as a long term strategy, people will start building larger robots.

    I am very curious to see how they adjust to deal with the large entry counts. The ability to use so many very nice kits as a base will continue to make the desired entry count go up.

    Thanks for the research!

  2. Derek,

    I think we’ll have to wait and see. There seems to be some confusion among the players here on how the rules will be interpreted. Keep in mind that some of the slots are already taken by the players that one some of the associated competitions.

    There is also a rumor/leak going around that ROBO-ONE is going to switch to only once a year (it has been twice a year so far). Apparently Tsukumo, who is one of the founding sponsors, let it slip in a promotional email they sent out a couple days ago, even though there has been nothing official released about it yet.

  3. Changing to once a year would be a pity, I didn’t realize the the interest of the organizers was declining to that extent. Seems to me like the abilities of the robots are just starting to get interesting!

    Oh well, nothing lasts forever I suppose.

  4. Oh, and keep your ears open at the upcoming event for any news! Thanks!

  5. I don’t think their interest has declined at all, they just want to encourage a lot more events, like Robo-Fight, Robo-Gong, Wonderful Robot Carnival, and others, that will feed into ROBO-ONE. Maybe they want to position it like the World Series.
