Tesla used humans to remotely control some capabilities of its Optimus robot prototypes at a recent event designed to generate investor enthusiasm for forthcoming products, according to people familiar with the matter.

Employees stationed elsewhere oversaw many of the interactions between the humanoid machines and attendees of last week’s “We, Robot” showcase near Los Angeles, said the people, who asked not to be identified discussing company operations. The Optimus prototypes were able to walk without external control using artificial intelligence, the people said.
