KAIST’s Humanoid v0.7 Demonstrates Advanced Robotics with ‘Moonwalk’ and Soccer Skills

The Korea Advanced Institute of Science and Technology (KAIST) is pushing the boundaries of robotics with its latest humanoid robot, v0.7. Recent demonstrations showcase the robot’s impressive agility, including a fluid “moonwalk” and accurate soccer shots, highlighting advancements in what KAIST terms “Physical AI.”

Technical Independence and In-House Development

Developed at the Dynamic Robot Control & Design Laboratory (DRCD Lab) under Professor Hae-Won Park, the 75 kg KAIST Humanoid v0.7 is designed to bridge the gap between laboratory agility and real-world utility. A key aspect of the project is a strategy of “technical independence,” with the DRCD Lab choosing to design and manufacture core hardware – including motors, gearboxes, and motor drivers – in-house Humanoidsdaily.com. This system-wide optimization is crucial for achieving the necessary torque-density and power-to-weight ratios for high-speed locomotion.

Physical AI: Merging Brain and Body

KAIST’s approach utilizes Physical AI, a technology that enables machines to perceive, interpret, and execute complex actions in real-world environments InterestingEngineering.com. Unlike traditional AI that primarily “thinks in words,” Physical AI provides robots with a sense of space and timing. This is achieved through a collaborative intelligence initiative led by Young Jae Jang, which trains robots to learn continuously through simulation and real-time feedback, rather than relying solely on large datasets.

Advanced Hardware and Actuation

The robot’s actuation system is based on a Quasi-Direct Drive (QDD) architecture, pairing high-torque motors with low gear ratios for responsiveness and precise control. A custom-designed 3K compound planetary gearbox achieves high gear reduction in a compact, single-stage configuration, resulting in a lighter and more efficient system InterestingEngineering.com. The KAIST Humanoid v0.7 can reportedly run at speeds of up to 10.7 feet per second (approximately 7.3 miles per hour or 12 kilometers per hour) on flat ground InterestingEngineering.com.

South Korea’s National Humanoid Strategy

This project is a central component of South Korea’s national humanoid strategy, aiming to demonstrate the nation’s capability to produce not only impressive demonstrations but also the foundational hardware and control policies needed for industrial-scale deployment Humanoidsdaily.com. Engineers are currently focused on enhancing the robot’s mobile and dexterous capabilities, with the goal of enabling it to perform more complex tasks such as carrying items or operating machinery.

KAIST: A Leading Research Institution

Founded in the early 1970s, KAIST is a leading South Korean university often compared to institutions like MIT Biz.Chosun.com. The university focuses heavily on research in areas including AI, robotics, physics, and engineering.
