India, Nov. 15 -- A Chinese firm has released a nightmarish video showing hundreds of humanoid robots marching in unison, in what it describes as the "first mass delivery" of its machines.

The video, shared by Shenzhen-based UBTECH Robotics, shows the industrial robots standing in neat lines before walking together in precision. The video, sleek and almost cinematic, was made to promote the launch of the company's second-generation model.

According to a report by the South China Morning Post, UBTECH said the mass delivery marks the start of production for its Walker S2 model, which it calls the world's first humanoid robot capable of swapping its own batteries. The company announced that deliveries would begin in mid-November.
