Dr. Guero’s Amazing Tightrope Walking Robot (Video)

Tightrope Walking Robot

Remember Dr. Guero, the robot builder that stunned everyone last year with his bicycle riding Primer-V2 humanoid robot? He's back with another astonishing robot feat. This time his Primer-V4 robot is a full fledged tightrope walker!

Pretty darn amazing, especially considering that just a few short years ago many of the hobby level humanoid robot builders were lucky to keep their robots balanced and upright while walking for an extended period or boxing in the ROBO-ONE ring.

The tightrope used for this feat was a 4mm diameter cable suspended 1 meter above the floor. The technical challenges were significant and considerably different from normal humanoid robot walking. When a bipedal robot walks on the ground the standard approach is to apply gyro sensor feedback corrections primarily to the leg servos to shift the center of gravity. The arms don't play a significant role.

With tightrope walking the arms and upper body play a much more critical role in shifting the robots center of gravity to keep it balanced and avoid crashing to the floor. Dr. Guero's blog doesn't mention the use of any safety net, but I'm sure he had to catch the robot quite a few times before he got it working perfectly.

The robot's feet have a small slot for the tightrope, which is fair enough.  A human tightrope walker in the circus would cup their feet and use their toes in the same fashion.

King Kizer Can Knock Your Block Off – Literally (Video)

king kizer

Nao Maru's ROBO-ONE champion robot, Great King Kizer, caused a real stir after it earned the Best of Show award at RoboGames 2012 last April. Ever since he brought home the Gold Medal, Maru has received endless questions about his design and competition strategies.

One of the most frequently asked questions, especially from the foreign press, was, "How hard can King Kizer actually punch?* Never one to duck a challenge, Maru decided to King Kizer's power is just as strong as human karate fighters several times his height and weight.

ROBO-ONE 21 Humanoid Robot Competition Rules Released

robo-one rules

The rules for the next ROBO-ONE Humanoid Robot competition have been released. There are no substantial changes to the rules, though the latest revision includes a new provision prohibiting the use of 'hooks'.

In other words, builders can't design robot appendages that would deliberately hook behind their opponents or get entangled in opponents wiring cables.  This does not rule out the use of grippers or techniques that involve grabbing or hugging opponents.

For most builders this doesn't represent much of a problem, though it may be a challenge to some aggressive competitors. I'm not sure how the new rule will apply to robots like King Kizer that have unique arm/hand designs.

The ROBO-ONE 21 competition is scheduled for September 1st/2nd, but the venue hasn't been announced yet.

ROBO-ONE Light 4 Humanoid Robot Competition – Pit Area

The ROBO-ONE Light series of competitions was developed to encourage novice humanoid robot builders to participate in the ROBO-ONE initiative. In other words, the ROBO-ONE organizers wanted to attract "new blood" and revitalize the movement.

All of the robots have to be based on robot kits from a list of authorized manufacturers and models. However, many of the builders have heavily modified the hardware and software to give them a bigger competitive advantage in the ring.

King Kizer: ROBO-ONE Champion Robot headed for RoboGames (Video)

I'm happy to announce that King Kizer, the awesome ROBO-ONE Champion robot created by Nao Maru, has signed up as part of the Robot Japan team for their 2012 U.S. Tour with an exclusive engagement at RoboGames, April 20th-22nd in San Mateo, California.

King Kizer took humanoid robot competition to a totally new level and inspired Japanese robot builders to ramp up their humanoid bots while accomplishing feats of speed, agility, and flexibility that was thought by experts to be impossible just a few years ago. As impressive as it seems, the video below can't begin to communicate how compellingly powerful, fast, and responsive King Kizer is in the ring.

ROBO-ONE Light: My Personal Favorite Image

120324 ROBO ONE Light 1

Of all the photos I took at the ROBO-ONE Light competition in Kawasaki last Saturday, and I took over 400+, this particular image is my hands down favorite.

That might seem a little strange, especially since there aren't any battling bots in view. There are several reasons why it speaks to me so deeply and completely. First, it shows two different generations, separated by several decades, yet sharing the same pure pleasure and concentration, connected by their love of the sport and the sense of accomplishment that comes from competing at this level.

Second, the gentleman smiling with intense pleasure behind the table is Terukazu Nishimura, the founder of the ROBO-ONE humanoid robot entertainment movement.

Over ten years ago he had a dream. That, in itself, isn't unusual. Everyone has dreams and aspirations. But Nishimura took it on himself to make his dream a reality. It didn't come easy. He had to take a lot of personal and financial risks, and he put his own personal credibility on the line as he convinced, cajoled, and encouraged everyone from major companies like Bandai and Sunrise, to smaller companies including Kondo and Futaba, plus a raft of hobbyists to get involved.

Of course it took the hard work and dedication of over a hundred volunteers and participants over the past decade to make the ROBO-ONE movement the success it is today.

Without Nishimura, without his dream, and without his unflagging focus and commitment, none of this would have happened. The lives of so many robot fans and builders, not just in Japan but all over the world, would be less enriched and a little sadder. His gift, his dream, has already blessed and inspired several generations.

So, when I see this photo, when I see the broad, happy, engrossed smile on Nishimura's face, I know, and I'm sure he knows, that it's all been worthwhile. I hope he understands the debt of gratitude and appreciation that all of us owe to him.

GAROO Retains ROBO-ONE Championship in the Final Match (Video)

120325 ROBO ONE 1

There have been many ROBO-ONE Champions since the well-known humanoid robot competition first started 10 years ago, but I'm sure that back in 2002 no one ever imagined that the same builder would win the title twice in a row, and that the competitor that did would be a woman.

That's exactly what happened this afternoon when GAROO, the reigning ROBO-ONE 19 champion, went head to head in the ring against Gargoyle Mini for the ROBO-ONE 20 championship, a huge trophy, and a cash prize worth approximately $12,000.
