Robosavvy was invited by Robotis to join the Korean Robot Games Festival this year so I (Pedro) was elected for the job.
I got here on the 3rd and I was with Robotis attheir office on the 4th and 5th on sessions about servo maintenance and also Roboplus.
One the 6th we moved to the hotel near the place where KRGF is being held and that's were all teams finally met.
The games are from Aug 7th until Aug 9th.
I appologise for not posting sooner but I've had really busy days with the guys from Robotis.
Robotis also invited other teams, and the teams that are here with the Robotis delegation are:
- Me (Pedro) from Robosavvy who entered the Amateur Fighting competition and also participated with Mireia from Robotica in Humanoid Soccer (I didn't really do very well in either....)
- Clarence from AMainObjectives (Singapore) with two students who entered the Humanoid Soccer competition
- The Farrels with their humanoids (more on this later as I got to see some cool stuff).
They have participated in the Opening Demo, Professional Fighting and also Humanoid Soccer (I think the decision to have them play there was a bit last minute but nevertheless they did very well).
- We also have the Giga Dynamizer from Japan, a really tall humanoid bbuilt using Robotis EX 106 servo (106 kgf not yet available in Europe) that entered the professional fighting competition.
- We have another team from Hong Kong who also entered Humanoid Soccer.
- There was also a team from the US who entered the autonomous mission.
I am am not completely of all the competitions the teams participated as we were in the backstage with our robots and there was a big crowd: 200 teams for Amateur Fighting, 100 teams for Soccer and some 50~100 more for Professional Fighting and Autonomous missions.
On top of this there was also a competition for Battle Robots which had another 40 teams I believe.
As you can see it is a really big event and this was only day 1.
About the competitions:
- The Humanoid Soccer competition is a competition with 2 humanoid robots per team that are Remote Controlled. This is not autonomous soccer.
- Amateur Fighting is really, well, amateur fighting. Most of the robots present were Kits (Bioloid, Robobuilder and one called Rocky) with some form of modification or custom assembly.
- Professional Fighting was made of custom built robots, most of them built using Dynamixel Servos.
Professional is divided into middle weight and heavy weight.
This year there was a change in weight where middle weight is only 2kg (it was 3 last year) so the Farrels had to go up against a 5kg robot and couldn't really make it to the finals....
I must say Robotis is really popular here.
A great number (if not almost all) of the custom designed robots that entered the Professional Fighting competition were built using Dynamixel Servos.
We also saw a great number of Bioloids Comprehensive as well as Bioloid Premium which apparently are being distributed in a small number in Korea at specific events.
I'll be organizing the pics and videos in the next few days as well as additional information.
You can find some of day 1 there which I believe can give you a good idea of the feeling and the competition.
As I mentioned I should be adding more and organizing them properly with tags etc in the next few days.
As I had mentioned none of the International teams invited by Robotis qualified for finals so the only thing left for u to participate was Robot Rumble. (Where all Robots go on the arena and wins the last robot standing in the arena).
The Farrels entered the competition as well as the Giga Dynamizer but the winner was actually another robot.
Robot Rumble is held just for fun at the end of the games.
We also saw the finals for junior league where most of the robots used are OLLO. This is something I believe I did not mention yesterday:
. Day 1 was all about humanoids and there were also Battle Robots.
. Day 2 was the junior league where they have some very fun and pedagogical competitions. OLLO Bug / OLLO Education (not yet available outside Korea) was present in mass scale.
It was amazing to see so many OLLO bugs in one place.
. Day 3 was for the finals.
I'll detail day 2 in my next post as I have tons of pictures that I wanted to upload.
In essence most of the competitions are remote controlled (like driving the bug to take 3 balls to the opponent field) but there are also line following competitions and also line following with obstacles where OLLO bots use a gripper to get obstacles out of the way.
Very advanced for kids in such a small age (under 10) but I guess if they can do it, so can we
With regards to the finals:
- The final for Autonomous Mission was really poor compared to our Robocup.
Autonomous mission consists of driving the robot to find a yellow cilinder and pick it up.
They do it in pairs of 2 robots so the one who gets it first wins.
The robots were cluncky, missed the target or lost it, fell down on each other..... very poor performances.
- The final for Amateur fighting was really good. The robots that got to the final were similar suggesting it's a robot kit.
The kits used Dynamixel AX 12 I believe but the frames were made of aluminum, were smaller than the Bioloid and much faster and well programmed.
They also had an amazing move where they grab the body of the oponent and tilt it. I also have a video on that to post.
(unfortunately I can't upload to youtube from Korea due to some Korean government restriction so I'll have to wait until get back on Tuesday.)
- The final for Professional Fighting was also interesting although it was basically an average sized humanoid against one which was 80~90cm tall.
It was built with Robotis EX 106 just like the giga dynamizer.
Apparently Robotis distributed quite a few of these 106 to some key developpers/testers because I saw 3 teams with these (The giga dynamixel, the farrels on their baseball playing humanoids, and the winner of Professional Fighting).
- Another fun moment was a fight between the winner of professional fighting and amateur fighting.
It was really all fun because the Amateur Robot is really small and made no harm to the giant.
- There were also the finals for Junior League with many OLLOs, the finals for Humanoid Soccer and the finals for Battle Robots.
The final for Battle Robots was really amazing and exciting because the robots managed to recover over and over form really tough situations.
To kick off the posting of pics and videos, here is the video from Day 1, when I was participating with Mireia from Ro-botics in the Humanoid Soccer competition and we were eliminated (this was game 2):
I didn't really work on programming these Bioloids but the motions were really slow and thus the performance was not that great.
I believe they were using standard/stock soccer movements that come in the beta versions of Bioloid Premium (not sure if/how it will be in the final version).
I'll continue to post more details within the next days.
The day before the competition, when all invited teams met:
You follow the links to the Youtube page, you can see the full description of the videos.
Both the Giga Dynamizer and the Baseball Robot from the Farrels are using the new EX 106 servos from Robotis.
One thing I've learned form them is that when the humanoid is not making movements with the arms or other extremities, they set up the parameters on the servos for greater elasticity.
This way if the robot falls, the gears are protected.

Day 2 was dedicated to the competitions of the younger ones.
We saw a huge number of OLLO Bugs.
Ollo is meant for schools to introduce kids, before they move on to LEGO.
The CM-100 controller uses Roboplus as well and can be used for activities like line following, obstacle avoidance, remote controller, etc.
This is one of the competitions where OLLO was quite popular. If you visit this video on youtube you can find further information on this competition.
This was a competition where the robots, assembled as spiders, had to go all the way up to the balloon and pop it. The first one to do it wins.
Bioloid based Spiders were also very popular for this competition.
Day 3 was only the finals so you can see a lot less people in the backstage pictures.
This was a fight between the winner of the Amateur Fighting and the Winner of Professional fighting (they made it just for fun).
The big one is using EX 106 servos.
The small one is from the winner form the Amateur category. You can see the difference in size!
The small one also looks like a kit because I saw more of these with the same set of pre programmed motions (a very good one BTW) which seems based on AX 12s as well. However I was unable to find more info about it.
This video is for the TinyWeb robot, developped by the creator of GigaDynamizer.
It sues AX 12 servos but are tweaked to work in an amazingly fast and precise way.
The tweaks are just around the stabdard AX 12 servo parameters available on any standard AX 12.
The Robot is really just for competition is it currently does not feature any sensors.
On the other hand the programming software is really advanced with Inverse Kinematics and things like interruption of gaits (for example you can set it up to interrupt a walking gait and indicate what to do to have the robot stop the gait but remain steady and transition to the other gait quickly).
