Hyundai Motor Group and Boston Dynamics have announced that they are conducting a soccer training project to advance the movements of the humanoid robot 'Atlas'. Drawing industry attention, this goes beyond simple sports learning and is part of the next-generation robot technology development process to implement natural, human-like movements.

[Overcoming a Robotics Challenge with 'Soccer'] In the field of robotics, implementing natural movements is considered one of the most difficult challenges. Humans simultaneously utilize balance, timing, muscle control, and environmental perception when walking, running, and changing direction, but there are significant technological barriers for robots to implement these complex movements.

To solve this, Hyundai Motor Group and Boston Dynamics selected 'soccer' as a training tool, which requires balance, physical coordination, precise timing control, and instantaneous situational judgment. Researchers are collecting movement patterns based on the biomechanical data of human soccer players and applying them to Atlas's motion algorithm.

[Virtual to Reality... Motor Skills Enhanced by Implementing the 'Rabona Kick'] Atlas first undergoes repetitive training in a virtual simulation environment and then goes through the process of reproducing the same movements in the real world. Researchers are improving the robot's balance and whole-body control capabilities, starting with the basic motion of kicking a ball and gradually increasing the difficulty.

In particular, the implementation of the 'Rabona Kick', a high-level soccer technique, is drawing attention from the industry. The Rabona kick is a technique of kicking the ball by crossing one leg behind the other, requiring rotational movement, weight transfer, and precise balance simultaneously, making it a highly demanding motion for a humanoid robot.

Researchers film human movements, convert them to fit the robot's kinematic structure, and use Artificial Intelligence (AI) to train the robot to perform the action. Afterwards, the method involves applying it to actual hardware for repeated verification.

[Expansion to Industrial Sites... Competition in the Physical AI Era Begins in Earnest] The industry explains that such research does not simply stop at creating a robot that is good at soccer. The series of processes itself—recognizing the ball's position, moving to it, and kicking it with the exact force and direction—is directly linked to the core capabilities required in the future in complex industrial sites, logistics environments, and disaster response scenes. This is because adaptability to respond to unpredictable environmental changes is essential for humanoid robots to be deployed in actual living spaces.

Recently, with the advent of the 'Physical AI' era driven by advancements in AI technology, the competition to develop robots that implement human-like movements is becoming even fiercer. Hyundai Motor Group is accelerating its efforts to secure competitiveness in next-generation humanoid technology through its partnership with Boston Dynamics, fostering robotics and AI as key future growth drivers.

An industry official analyzed, "Soccer is a sport that condenses human physical abilities," adding, "If humanoid robots acquire motor skills capable of playing soccer, their scope of utilization in future industrial sites and daily life can be significantly expanded."
