Humanoid Robot processing postal letters.

Another jump in the postal mail

A synthetic workforce capable of reading, separating and dispatching thousands of letters and packages per hour without needing a break, Chinese automation has just reached one of the most traditional pillars of public infrastructure, the postal service. In June 2026, China Post placed humanoid robos to work in one of the country's largest mail processing centers.

The state-owned China Post Group decided to integrate humanoid robots into a gigantic logistics center responsible for processing nearly 6.5 million packages per day. In that environment, new synthetic workers operate alongside autonomous forklifts and traditional robotic arms, forming an automation chain that operates virtually seamlessly. The details disclosed by the state press reveal the autonomy of the machines chosen for this mission.

The model used is the Shin Down L7, developed by the Robot Era company. Although the platform could receive legs in the future, engineers opted for a fixed configuration by installing the robos on pedestals along the sorting belts. The focus is not on mobility, but on precision. To locate each package, L7 uses a 360º vision system based on three-dimensional border sensors, this spatial perception feeds arms with 7 degrees of freedom and hands equipped with 12 independent joints, prioritizing finger dexterity and fine manipulation capacity.

The justification for introducing these machines into the postal system is operational consistency. According to data released by People's Daily, groups of robots working together manage to maintain a stable rate of approximately 122 packages per hour. Unlike humans, metal does not suffer from muscle fatigue or injuries caused by repetitive movements during long night shifts. But the engineering reality is still far from perfection. Despite the marketing campaign around robots, pure speed remains a territory where humans maintain an advantage.

A comparative test carried out by Figar AI in the United States revealed that an ordinary human intern, even interrupting work for breaks and meals, managed to separate 192 more packages than a humanoid during a full 10-hour shift. This shows that artificial intelligence wins in perseverance and endurance, but still does not reach the capacity for instant reaction and adaptation of the human brain. Even so, the presence of these humanoids within the Chinese postal infrastructure reveals something much greater. For the first time, governments are demonstrating enough confidence to hand over critical parts of essential services to machines.
