Wang Tingting observes a robot writing in Changchun, northeast China's Jilin Province, April 21, 2026. Inside the training ground of a bionic robot innovation center, robot engineer Wang Tingting, wearing motion-capture equipment, guided bionic robots through tasks such as grasping, walking and laying. The robots undergo stages including action demonstration, data collection, precise calibration, and repeated error correction.

What appears to be a simple sorting action requires Wang Tingting to repeat it hundreds of times to ensure the robots operate accurately, stably, and safely in real environments. (Xinhua/Zhang Nan)
