• MH-2 Wearable Communication Robot

Our friends at IEEE Spectrum continue to cover ICRA 2012, and they’ve scored another scoop on one of the projects we were most excited to see.  The MH-2 (Mini Humanoid) Wearable Communication Robot was presented by Yuichi Tsumaki, Fumiaki Ono, and Taisuke Tsukuda of Yamagata University’s Telerobotics Lab.

The Telerobotics Lab has played with the idea of wearable humanoid robots for the past decade.  Earlier we looked at their T1 Telecommunicator, which featured a very simple humanoid that sat on your shoulder and could wave its arms and look around.  The idea is that the carrier takes the robot avatar (and by proxy, its operator) with them where ever they go, providing them a form of tele-existence.  Others have explored similar ideas, such as ATR’s Elfoid, and MIT’s MeBot, but those are more like a cellphone that you would call than a robot avatar that is constantly on.

The operator of the robot controls its actions through a simple motion-capture set-up (using a Kinect sensor, for example), or through a GUI on a computer.  And the MH-2 is equipped with a stereo camera rig that allows the operator to see the carrier’s surroundings in immersive 3D while carrying on conversations through a microphone and speaker.  Let’s say you want to take a distant or bedridden friend on a tour: they can “jack in” to the robot and experience your surroundings as you show them around.

As you can see in the video, the MH-2 is capable of much more sophisticated movements than comparable robots thanks to its 20 degrees of freedom, allowing for more natural body language to be conveyed through it’s diminutive upper-body.  Each arm has 7 degrees of freedom (including a nifty 3-DOF wrist), 3 in its neck, 2 in its body, and (rather remarkably for a robot) an extra DOF that causes its chest to look as though it is inhaling and exhaling.

Similar to Samsung’s miniature humanoid April, the MH-2 offloads the bulk of its 22 actuators through a bundle of wires.  They lead to a backpack worn by the carrier which looks a bit cumbersome, but seems a bit less so than the T1′s configuration.  Currently the robot relies on a human carrier, but it would be equally at home on its own mobile base.  In that case, the operator would take control of navigation and the robot would function as a standard telepresence robot rather than a wearable one.

China’s First Self-Balancing Unicycle Robot

Back in November 2011 Prof. Xiao-Gang Ruan and six graduate students from the Artificial Intelligence and Robotics Research Institute of the Beijing University of Technogy demonstrated a cute self-balancing unicycle robot at the Beijing museum.  It was one of a handful of student projects on display at the Creative Bazaar during the sixth annual Beijing International Cultural and Creative Industry Expo.  Many of the projects on display, such as single-passenger electric vehicles, emphasized environmental concerns.  Other projects included a saucer-shaped drone aircraft, and art installations.

Although it is not the only self-balancing unicycle robot in the world (see Murata Girl), it is a first for China.  The robot is capable of balancing at a fixed point, can move forward and backward, and can compensate for external disturbances.  Its developers say the robot can also navigate a balance beam, but this feat was not part of its public demonstration.

For now it’s purely an entertainment robot, but it could be used as a guide, to transport goods, or perform security patrols.  The look of the robot was produced in collaboration with Spring Design, a company which produces product designs for multinational corporations like Panasonic (see some conceptual renderings after the break).

Videos: DARwIn-OP Humanoid Application Challenge

The DARwIn-OP Humanoid Application Challenge took place at ICRA 2012 in Minnesota this month.  The goal of the challenge was to promote innovative, open-source projects in the DARwIn-OP community.  More than 13,000 students participated but only nine teams made it to the finals.  Projects were judged by Professor Dennis Hong (Virginia Tech), Professor Daniel Lee (University of Pennsylvania), and peer review among the finalists.

The winning team hails from The University of Manitoba’s Autonomous Agents Laboratory, who’s hockey-playing DARwIn-OP (nicknamed Jennifer) was able to “skate” on ice and rollerblades and shoot a puck with a pint-sized hockey stick.  As might be expected, the project quickly made headlines and appeared in broadcast news segments across Canada earlier this year.

Another fun project came courtesy of a team from Drexel University’s Autonomous Systems Lab, who programmed the robot to drive a Roomba using a simplified steering column, acceleration, and brakes.  The robot’s vision system was able to track a black line, which informed it when to turn left and right.

Book Review: Loving The Machine

Loving The Machine examines Japan’s unique relationship with robots. Author Tim Hornyak begins with a lesson on Japanese puppets and karakuri ningyo, which like Western clockwork automata can be considered the ancestors of modern robots. They’re not so far apart; Toyota’s wire-based robot and band are really nothing more than the modern expression of these traditions.

When, in the early 1920s, Japanese theaters produced Karl Capek’s R.U.R., it didn’t set audiences on fire.  But its robots, and those in movies like Fritz Lang’s Metropolis proved universally popular, inspiring people around the world to write science fiction novels starring mechanical men or create animatronic statues.  Japan was no exception, though many early “robots” (more works of art than robots in the true sense of the word) have been lost and have had to be reproduced based on photographs and precious diagrams.

Post-war interest in robotics was given a shot in the arm through popular comics and animated tv shows like Astro Boy and Gundam. A summary of the most popular series examines how the genre has evolved over the years from relatively simple beginnings to complex character studies. In this way, the first seventy odd pages establishes the context in which Japan was able to embrace (rather than fear) robots in all their forms. Of particular note is Japan’s rapid adoption of industrial robots, which were invented in the United States.

Guest Interview: Anthrobotic x Cybernetic Zoo

This week we’re hosting our first guest post ever.  It comes to us courtesy of the sometimes snarky but always entertaining Reno J. Tibke, the owner and operator of  This is his interview with Reuben Hoggett, the author of, a huge archive of robot-related projects from the 20th century.  Enjoy!

anthrobotic: Hello, Mr. Hoggett. Let’s jump right in: what exactly is

The site is intended to be a resource on 20th century cybernetic machines, humanoid robots, and walking machines. It diverges now and then as some earlier interests rekindle themselves to the point of starting a new category, e.g., pneumatics in robots.

anthrobotic: And you occasionally dip into into the 21st century as well, yeah?

Yes, mainly if there are minimal items and the original idea has been re-born, e.g., exoskeletons, walking rickshaws, human-powered walking machines, and the like. Not modern humanoids such as ASIMO, they’re too numerous for the time it would take, and they are adequately covered by many others out there.

anthrobotic: Your site is an excellent resource, no doubt, but it’s pretty obscure. I found you through a very specific keyword and image query, and aside from search indexing or backlinking from the sites you’re sharing, email appears to be the only way to connect. Any desire to promote or gain wider exposure?

Most people who have contacted me via the site have been amazed by the researched material presented. I have helped several thesis students. Unfortunately, I’m not a website expert and some good info gets buried. But it is a treasure find for those who do scroll beyond the opening page. My only regret with a much larger audience would be my inability re: lack of available time to respond adequately to their questions, assuming they want to contact me.

anthrobotic: Okay, if not for money or fame, why did you build it?

My interest in all things robots is a lifetime one. Since a boy I had scrapbooks of robots, computers, rockets, flying saucers, medical science advances, telescopes, and other popular science topics. I think I reached a point where I asked myself what was I going to do with all this material, and I had a sense of, whilst it was a personal collection, it was potentially unique, and the last thing I wanted was for a lifetime’s effort to be trashed when I eventually pass away.

I first started sending articles about Edward Ihnatowicz and his cybernetic sculptures to Alex Zivanovic who has a wonderful site on the Senster. I also looked around for a similar site for my material, and that started the wonderful and ongoing relationship with David Buckley and his website on Robot History Makers.

I need to digress slightly. One of my other passions in life is classic Italian sports motorcycles, and noticing that some of the key engineers of the era were dying off, e.g., Taglioni of Ducati, Tonti of Moto Guzzi, etc., it occurred to me that possibly no one was recording the life of these unique individuals. Naturally, it also occurred to me that no one was recording the stories of the pioneers of cybernetic machines (e.g., Grey Walter) and robot artists (e.g., Bruce Lacey).

So in 2009 I planned a trip to Europe, including the UK, to at least catch up with those I was particularly interested in and whose contact information I could get. The trip included a visit with David Buckley, who eventually asked if he could join me. After that, I knew David didn’t have the time to publish more of my material, and that some of my interests were outside his main theme. I bit the bullet and started my own website.

Boston Dynamics Breaks Speed Record for Legged Robots

A number of quadrupeds are in various stages of development for DARPA’s Maximum Mobility and Manipulation (M3) program.  In the past few months both Boston Dynamics and MIT’s Biomimetic Robotics Lab have published video footage of their robots in action.

Boston Dynamics is the program’s frontrunner.  It’s old news by now, but their nearly complete prototype has broken the land speed record for legged robots at 28.9 kph (18 mph). The previous record was set by the MIT Leg Lab’s pogo stick-like Planar Biped robot back in 1989.  It too was co-created by Marc Raibert, and bounded at a speed of 21 kph (13.1 mph).

Cheetah is still tethered to an external power source and uses a boom to keep it centered on its treadmill, but the company says it will test an “unplugged” version later this year. If that doesn’t get you excited, Raibert has speculated that, with some improvements, the robot could achieve speeds of 64.3 kph (40 mph). Even if it eventually runs that fast it would still be slower than its flesh-and-blood inspiration, which has a top speed of 120 kph [75 mph]).

• Xianxingzhe

NUDT’s prototype biped robot

Waseda University’s humanoid and bipedal walking robots seen at the Expo ’85 world fair in Tsukuba inspired researchers from the Chinese National University of Defense Technology to build one of their own.  Having previously built an amphibious snake-like robot and some insect-like hexapods, a humanoid seemed like a suitable challenge.  In 1987 the researchers had managed to get a simple bipedal robot to walk, and in 1989 they began work on the upper body.  Finally on October 29th, 2000 they were ready to unveil the completed Xianxingzhe (先行者), which translates as “forerunner” or “pioneer”.

The final robot was able to walk at a rate of 2 steps per second, stood 140 cm (4’7″) tall, and weighed 20 kg (44 lbs).   It was controlled by an embedded PC and had a total of 17 degrees of freedom (head x1, 2 arms x2, 2 legs x6) powered by 100W motors.  The shoulder joint and elbow joint moved synchronously.  The lights in its eyes would blink, it was able to walk, turn, ascend stairs and step over small obstacles measuring about 4 cm (1.5 inches).  Interestingly the ears are actually speakers, not microphones!  The researchers believed that this technology could find practical use in limb rehabilitation, or perform work in toxic or radioactive areas.

As the first walking humanoid robot built in China it was a major technological breakthrough for the country, but its gangly appearance and simple (some might say cute) smiley face made it an easy target.

The victim of unfortunate timing, it was revealed the same year as Honda’s ASIMO, prompting a Japanese website to make direct comparisons between the two.  That Xianxingzhe was developed for a fraction of the cost made little difference to the average netizen, and the page satirizing the robot quickly grew in popularity.  Because the robot was built by a university of “defense technology”, the page claimed the cylindrical motors in its hips were actually a secret weapon: a crotch cannon.  A second page included humorous animated .gifs that showed how the robot would charge up its energy by rapidly squatting before letting loose a massive attack with a mighty pelvic thrust.

Video: Dr. GIY’s Dancing Robot Maid

Dr. GIY (a prominent member of the Japanese ROBO-ONE community) has designed and built a new custom robot.  At 52 cm (20.4 inches) tall Pre-maid Me won’t be doing the housework any time soon, but with a total of 27 degrees of freedom is capable of some pretty fancy footwork!  As is typical of most Japanese do-it-yourself robots, this one was built and programmed using Kondo servo and software (available in kit form as the Kondo KHR-3HV).

According to Dr. GIY, the robot’s dance routine is still a bit rough around the edges.  Once finished, we can expect something similar to his excellent choreography with this catty Manoi AT01.
