kateboarding Humanoid Robot: Japan's ATR, Kyoto University & AIST Develop Next-Gen Robotics

By JapanTalkback Editorial Published Jan 11, 2026 JST Updated Jul 12, 2026 JST 4 min read

A collaborative research team from ATR (Advanced Telecommunications Research Institute International), Kyoto University, and the National Institute of Advanced Industrial Science and Technology (AIST) is developing a humanoid robot capable of freely riding a skateboard. On September 11, 2025, the team unveiled a robot (152 cm tall, about 40 kg) powered by ATR's "Cyborg AI" that performed slalom skateboarding, achieving human-level real-time motion performance. Commissioned by NEDO and running since 2020, the project may prompt a "Why a skateboard?" reaction, but it encapsulates critical technical challenges essential for practical humanoid robot applications.

Why Skateboarding?

Skateboarding is one of the most challenging skills even for humans to master. It requires maintaining balance on an unstable board while controlling direction through weight shifts and responding instantaneously to changes in the road surface. If a robot can accomplish this complex task, it demonstrates breakthroughs in several key areas:

Dynamic Balance Control: Maintaining posture under constantly changing conditions, not just in static states
Predictive Control: The ability to anticipate upcoming changes and respond proactively
Whole-Body Coordination: Complex movements integrating arms, legs, and torso in unison
Environmental Adaptability: Real-time response to changes in surface conditions

Global Humanoid Robot Development Landscape

Boston Dynamics "Atlas"

Boston Dynamics' "Atlas" has amazed the world with its advanced athletic abilities, performing parkour and backflips. In 2024, the company unveiled a fully electric new Atlas, aiming for practical applications in manufacturing and logistics.

Tesla "Optimus"

Tesla, led by Elon Musk, is pushing Optimus toward mass production. As of 2026, it is retooling factory lines for the next-generation model, targeting industrial applications first.

Honda "ASIMO" Legacy

Honda's "ASIMO," introduced in 2000, made a global impact as a pioneer in bipedal walking robots. While the ASIMO project has concluded, its technology continues to influence next-generation mobility development.

Figure AI "Figure 03"

Startup Figure AI, reportedly valued at around $39 billion, ended its OpenAI partnership in February 2025 and switched to its own in-house AI model, "Helix." In October 2025 it unveiled its latest robot, "Figure 03," which is now being deployed on BMW's factory floor.

China's Rapid Advancement

In China, multiple companies including UBTECH and Unitree have entered humanoid robot development, rapidly advancing their technological capabilities with government support. They aim to capture market share with competitively priced products.

Japan's Strengths and the Significance of This Research

Japanese robotics technology has led the world in industrial robots. However, in the humanoid robot sector, the rise of American and Chinese players has been remarkable in recent years.

The ATR, Kyoto University, and AIST collaboration is not merely a "showpiece" but holds significant importance in several ways.

Deepening Fundamental Research

The fundamental research approach unique to universities and research institutions allows tackling root technical challenges without rushing toward commercial results.

Industry-Academia-Government Collaboration Model

The cooperation between different types of organizations, ATR (private research institute), Kyoto University (academic institution), and AIST (national research and development agency), enables a multifaceted approach.

Real-World Application Potential

Technologies developed through skateboarding directly translate to practical applications, such as robots navigating debris at disaster sites or construction robots moving across unstable scaffolding.

Technical Challenges

Developing a skateboard-riding robot presents several technical difficulties.

Sensor Technology

The robot must perceive its own posture, board tilt, and road conditions in real-time. High-precision IMUs (Inertial Measurement Units) and force sensors are key.

Control Algorithms

To handle unpredictable disturbances, hybrid approaches combining Model Predictive Control (MPC) and reinforcement learning with traditional PID control are required. In practice, the Cyborg AI predicts 500 possible next motions, completing what amounts to 28 hours of computation in a single second and continuously selecting the optimal move to keep the robot stable in real time.

Actuator Performance

Actuators capable of delivering large forces instantaneously while also enabling delicate control, similar to human muscles, are essential.

Future Outlook

If this research succeeds, humanoid robot capabilities will advance significantly. Future applications may include:

More natural assistance in nursing and welfare with fluid movements
Off-road mobility for disaster rescue operations
Flexible task handling at construction and manufacturing sites
Applications in sports training and education

Japanese robotics technology may once again lead the world.

What Japan Is Saying

ATR, Kyoto University, and AIST—what an impressive combination. Being able to do this kind of industry-academia-government collaboration for fundamental research is one of Japan's strengths.

Honestly, Japan feels behind compared to Boston Dynamics' Atlas... But I hope this kind of steady research will lead to future breakthroughs.

It's interesting as research, but is it worth spending taxpayer money on this? I'd rather see investment in more practical things.

As an engineer, let me say that skateboarding is an ideal problem setting for dynamic balance control research. It tests the ability to respond to unpredictable disturbances.

If robots can ride skateboards, surfing next? lol Actually, predicting waves would be super difficult.

Japan's robotics tech is world-class in industrial applications, but has low visibility in humanoid robots. I hope research like this helps us catch up!

I work in elder care. If this technology eventually leads to robots that can move reliably even in unstable environments, it would be a huge help.

Ever since ASIMO ended, humanoid research in Japan seemed to quiet down. I'm happy to see it heating up again like this.

Impressive work from Kyoto University researchers. I think this research topic strikes a good balance between academic curiosity and practicality.

Feels like Tesla's Optimus and Chinese robots are overtaking us. Japan needs to speed up development with commercialization in mind.

I'm a university student studying control engineering. I definitely want to read the paper when this research is published. Curious about the MPC and reinforcement learning combination.

Want to see the video! Curious about what level they can actually ride at.

Research like this often ends without technology transfer to companies. I'd like to know the roadmap to practical application.

I work as a robotics engineer, and this kind of fundamental research supports product development 10 years down the line. Please don't just demand short-term results.

AIST might be low-profile, but it's a crucial institution supporting the foundation of Japan's technological capabilities. It deserves more attention.

Will bipedal robots like Gundam really become reality someday? So exciting to think about.

As someone in construction, I'm hopeful. Job sites are full of unstable footing, so without this kind of technology, robots won't be usable.
