铁憨憨 (tiě hān hān) — Iron Dummy — affectionate nickname for robots

Example Usage

那个送餐机器人卡在门口转圈，真是个铁憨憨。

That food delivery robot got stuck spinning in the doorway — what an iron dummy.

Cultural Context

铁 means iron/steel; 憨憨 means lovable fool. The term captures Chinese internet culture's fondness for robots that try their best but fail visibly. As Meituan, JD, and other companies deploy delivery robots in Chinese cities, 铁憨憨 moments — shared widely on Bilibili — have become a minor genre of viral content.
