The company has entered four robots across roughly 40 events of the WHRG, all running on its Huisi Kaiwu operation platform, which sets "higher and faster" as the track target and "better at working" in the scenario events, the company said.

　　Similar contests began two days earlier. On Sunday, humanoid robot competitors "checked in" at the Beijing Continental Grand Hotel. Given 30 minutes, each robot had to wheel guests" luggage to an assigned room, restock towels, slippers and bottled water, then clear the dirty linen and make the bed, according to a post on the official WeChat account of the WHRG.

　　The scoring shows what the organizers are after. Li Ziye, who runs the hotel event, said that finishing within the time limit does not by itself earn a high score: neatness is marked, and an autonomous run is weighted at 1 against 0.5 under teleoperation. The household event applies the same discount, said the post.

　　Li listed what a working building throws at a machine: unstructured space, soft goods that change shape, a loaded trolley that is hard to balance, and a task chain long enough to expose any instability. Zhang Yizhuo, from a joint Renmin University and X-Humanoid team, put it plainly: the corridors were narrow, making luggage handling a test of manoeuvring in tight space, the post said.

　　A library shelving event was held on the same day. Inside a working library, robots had 30 minutes to collect returns, shelve books and correct misplacements — a test of precision, visual recognition and reasoning, said another post by the WHRG on Tuesday.

　　One competing team said that the scenario events were close to reality and amounted to an examination of how far humanoid robots have come — preparation, along with industrial validation, for the day robots become genuinely useful, according to the post.
