On April 19, 2026, the Honor Lightning robot completed a half-marathon in 50 minutes, outperforming human record by 7 minutes. This performance marks a significant leap in robot running efficiency and technology.
The Honor Lightning humanoid robot achieved a remarkable half-marathon time of 50 minutes and 26 seconds on April 19, 2026. This performance surpassed the previous human world record by 7 minutes and improved on the best robot time from 2025 by nearly 2 hours.
The mechanics of running involve alternating phases: the stance phase where the leg pushes against the ground and the aerial phase where the body is airborne. Efficient robots must balance these phases to minimize energy use and maximize speed.
While specific details of the Lightning's motors are not disclosed, an analysis of similar motor sizes indicates that gear ratio plays a critical role in performance. Adjusting gear ratios affects torque production and heat generation, which are crucial for efficient running.
Using a physics model, an optimal gear ratio of 45:1 is identified for running at a speed of 7 meters per second, which corresponds to the Lightning's average speed during the race. This optimal configuration minimizes power consumption and heat generation.
