Once the stuff of science fiction, long-distance walking robots are now making headlines. The humanoid robot A2, created by Chinese company AgiBot, walked 106.286 km over three days, earning a Guinness World Record for the longest continuous walk by a bipedal robot. The feat showcases impressive technological progress but also raises questions about autonomy, transparency, and the hype surrounding robotics.
A2 Walks 66 Miles Nonstop from Jiangsu to Shanghai
From November 10 to 13, 2025, A2 journeyed 66 miles from Jinji Lake in Jiangsu province to Shanghai’s Bund district. Guinness confirmed that the robot remained powered on throughout, with only its batteries swapped while it kept moving.
Videos show A2 navigating sidewalks, ramps, and various flooring under different lighting conditions. According to AgiBot, the robot used two GPS modules, lidar sensors, infrared depth cameras, and navigation systems capable of handling traffic lights, urban traffic, and environmental changes. Guinness recognized the walk as autonomous.
However, a gray area remains: the video footage is heavily edited and does not clearly show how much human supervision was involved. Even if operators were present to monitor the robot, it wouldn’t necessarily invalidate the test—but there is still no independent verification that A2 acted entirely on its own from start to finish.
China-U.S. Robotics Rivalry Faces Scrutiny
This milestone comes amid a growing rivalry in robotics between China and the United States. Yet history advises caution. Elon Musk, for instance, has released videos of Tesla robots performing complex tasks like folding clothes or serving drinks, which later turned out to be teleoperated—controlled off-screen by humans.
Such demonstrations are common in robotics: they generate excitement but often blur the true level of machine autonomy.
It is possible that A2 completed its journey without direct human control. Technology is advancing quickly, especially in Asia, where significant investment is going into bipedal robots capable of operating outdoors beyond controlled labs. The current challenge isn’t walking itself—it’s sustaining long-distance walking with durable batteries and reliable autonomous systems.
While the record is remarkable, science reporting demands caution: major achievements need verification and transparency.
For more than a century, humans have dreamed of robots serving them. Yet many celebrated milestones were illusions—including well-known “robot” demonstrations that were simply actors in disguise. The takeaway is clear: genuine progress exists, but it must be examined with a critical eye.
Whether under supervision or fully autonomous, A2 has elevated the China–U.S. robotics competition, and this achievement may mark just the beginning of the humanoid era’s long-distance milestones.
