I spent a day at a robot “carnival” in Shanghai. Here’s what I saw.

A robot carnival near Shanghai gave families a close look at China’s rapidly expanding robotics industry. Entertaining displays highlighted the country’s progress in humanoid robots, as well as the safety, cost, and battery-life problems that continue to limit the technology.

上海附近的一场机器人嘉年华让许多家庭近距离了解中国快速发展的机器人产业。精彩的展示既体现了中国在人形机器人领域取得的进展，也突显出安全、成本和电池续航等仍在限制这项技术的问题。
