Humanoids dance and thread needles as Japanese robotics developers look to outdo Chinese

TOKYO -- Mechanical hands dexterous enough to thread a needle, childlike dancing robots and adult-sized ones to help with deliveries were on display Thursday as the Humanoids Summit Tokyo opened.

Among the dozens of companies taking part, including well-known players like Boston Dynamics and Toyota Motor Corp., the big stars now were clearly the Chinese.

Chinese newcomers, like Booster Robotics and LimX Dynamics, took the technology initially developed in Japan and the U.S. and fine-tuned it, often for cheaper mass production. It’s a repeat of what happened in other Japanese industries, from consumer electronics to cellphones and electric vehicles. In humanoids, Japan was initially ahead but then failed to produce major commercial solutions.

Tim Hornyuk, author of “Loving the Machine: The Art and Science of Japanese Robots,” who was at the event, categorized it as the so-called “Galapagos syndrome,” referring to how innovative Japanese products evolve in isolation and end up not translating for the international market.

“I really hope that Japan can come up with a Ford Model T-version of humanoid roots. But I think China has already stolen their lunch. It’s a bit too little too late,” he said.

The dancing and wiggling Mini Pi Plus robot from High Torque of China, for instance, still can’t help at an auto plant or do your dishes. But it’s cute. And it doesn’t come with an eye-popping price tag, starting at $5,500.

One telling example of Chinese robotics use in Japan was GMO, a Tokyo-based AI and robotics company working on a humanoid with camera eyes that will help with Japan Airlines cargo and other chores at an airport.

The key is to have the robot do the work in the same way as people so they would be interchangeable, an initiative meant to tackle the labor shortage problem that is increasingly serious in Japan.

The inner robotics workings were all courtesy of Unitree, a Chinese outfit, which is also working on a four-legged dog-like “stellar explorer.”

Experts say Japan, with its finesse in manufacturing, proved a good breeding ground for robotics development. The sociological backdrop of a public receptive to robotics also helped.

A recent Pew global survey showed that people in Japan are highly aware of AI but are less anxious about it, at about 28%, than people in the U.S. at 50%.

Japanese automaker Honda Motor Co., a leader in robotics with its walking humanoid Asimo, first shown in 2000, was demonstrating a motorized four-fingered robotic hand that could screw on and off tiny bolts, or thread a needle.

It didn’t seem to bother Keisuke Tsuta, assistant chief engineer, that similar mechanical hands were on display galore near his booth, many of them from Chinese makers.

The technology Honda had developed is more durable and powerful than rival offerings, and the Japanese have historically shown they can excel at quality mass production, according to Tsuta.

The looming threat of a Chinese robotics domination didn’t seem to phase Osaka University Professor Hiroshi Ishiguro, who has worked on humanoids for decades, including one that’s his clone.

“What’s significant is that Japan has a culture that’s receptive to robotics. If we’re going to really start using robots in society, Japan is the ideal place,” he said, stressing that Japanese don’t discriminate against robots.

His robotic counterpart, dressed all in black like the professor, did as good a job, if not better, of answering a key existentialist question on the meaning of robots.

“I think robots will coexist with people. Robots are the mirror of human beings,” the robot replied in a slightly monotonous but human-like voice.

Earlier, the professor had answered a similar question, but a bit differently.

“No one is interested in me. All everyone cares about is my robot,” he said, sitting next to his twin-like humanoid.

“As long as people identify with what I have produced, I am a success,” he added.
