On August 18th, as reported by media outlets, the 4x100m relay race at the 2025 World Humanoid Robot Games has concluded successfully. The Unitree Robotics team secured the championship with a commanding performance, finishing in 1 minute and 48.78 seconds. Beijing Teyun team and Walker Taishan team followed, taking the second and third place with times of 2 minutes and 22.79 seconds, and 2 minutes and 37.68 seconds, respectively.
The unique challenge of the relay race lies in the baton exchange, which demands a high degree of precision. According to the rules, the receiving robot can initiate its start at any position within the designated exchange zone. A successful handover is officially recognized when the passing robot and the receiving robot make physical contact within this zone, meaning any overlap or intersection of their bodies. Teams that fail to complete a valid exchange within the specified area will incur time penalties.
An operator from the Unitree Robotics team commented post-race, “The relay segment is the most difficult part of the competition. It requires two robots to precisely exchange the baton within the same lane and exchange zone. Furthermore, the passing robot must ‘overtake’ the receiving robot, meaning its body must extend past its teammate’s position.”
However, the limited width of the track significantly amplifies the operational complexity. Any minute deviation in coordination, especially at high speeds, can easily lead to collisions and subsequent falls. Consequently, the entire process necessitates extremely careful and precise control from the operators.
