According to sources, at the recent Robotaxi conference, tesla used artificial intelligence to remotely control some functions of its 'Optimus Prime' robot prototype to boost investors' enthusiasm for this upcoming product.

Unnamed sources requested that at the 'We, Robot' conference held near Los Angeles last week, employees from other locations were responsible for supervising many interactions between the humanoid robot and attendees. Sources said the 'Optimus Prime' prototype can indeed walk via artificial intelligence without external control.

Some attendees later expressed on social media that the robot received assistance. At least one video from the event site claimed a 'Optimus Prime' bartender acknowledged receiving 'human help.' Tesla CEO Elon Musk did not mention this in a recent webcast.

The use of human input has raised doubts about the robot's capabilities and market readiness. Musk stated last week that he expects this robot to become 'the biggest product ever.' He told everyone that the robot can handle many household tasks and may eventually be sold to consumers for between $20,000 and $30,000 each.

While Tesla had previously showcased the prototype of the 'Optimus Prime' robot, last week was the first time non-employees had the opportunity to interact directly with the robot. They served drinks to attendees, high-fived, and even played rock-paper-scissors.

The performance of this robot has long been closely watched by investors, although the product's release date is still uncertain. Observers noted that in 2022, early prototypes had to be carried onto the stage by people. Tesla also released updates showing the robot's ability to sort blocks and dance.

Sources said tesla had not originally planned for the 'Optimus Prime' robot to appear at the Robotaxi conference, but Musk requested their inclusion about three weeks ago. This source mentioned that the last-minute notice meant there was not enough time for software upgrades, so remote operation was necessary.
