Look out, there's a robot just waiting to take over your job

They are cheaper, don't get tired, won't strike, and they might be better than you. Yan Yiqi reports.

In a restaurant newly opened in Chengdu, capital city of Sichuan province, four robots are busy waiting tables.

The robots, 1.3 meters tall and capable of lifting up to 3 kilograms, can deliver dishes, collect empty plates and communicate with customers in simple sentences.
