Tesla is pitching Optimus as the next major breakthrough, but a recent onstage mishap has lawmakers and investors rethinking just how autonomous the robot truly is.
At an event in Miami labeled Autonomy Visualized, a humanoid robot handing out water bottles tumbled backward after its arms moved toward its head, a moment captured on a Reddit video. The clip surfaced soon after Russia unveiled its first AI-powered robot, which also took a nosedive onstage. The Tesla demonstration was intended to showcase both Autopilot technology and Optimus, according to Electrek.
The tumble happened when the robot knocked several water bottles off a desk while demonstrating its movement. To many online observers, the incident resembled a human reaction, fueling speculation about whether the robot was wearing a VR headset or experiencing some other kind of malfunction. Tesla did not respond to Fortune’s request for comment.
This moment stands out because Tesla has previously staged events with hands-on Optimus demonstrations. In last year’s robotaxi unveiling, attendees could interact with Optimus robots in person, with demonstrations ranging from playing rock-paper-scissors to pouring drinks and posing for photos. It later emerged that some of those bots were remotely controlled by humans, though Tesla did not advertise this practice. At least one Optimus unit admitted, in a different report, that it was “assisted by a human; not yet fully autonomous.” The Los Angeles Times noted that human operation may have been a workaround tied to Musk’s last‑minute event requests.
Tesla has long trained its robots using workers outfitted with motion‑capture suits and VR headsets, a setup that fed into public demonstrations. While the company has leaned on human operators for some show moments, Elon Musk has repeatedly asserted that Optimus can operate autonomously in other contexts.
On social media, Musk has defended the robot’s autonomy. He pointed to moments where Optimus appeared to perform tasks—such as martial arts demonstrations—without real-time human control. He even cited appearances alongside actors (for example, at the Tron premiere) where the robot’s movements were described as AI-driven, not tele-operated, noting that many spectators mistook the robot for a living person.
Despite Musk’s assurances, it remains unclear how much of Optimus’s behavior relies on human assistance versus autonomous AI. Yet the executive team has positioned Optimus as central to Tesla’s future, calling it “the biggest product of any kind, ever.” He has even framed Optimus as a potential driver of substantial company value, suggesting that a production line capable of manufacturing up to 1 million Optimus units annually could be in place next year.
Fortune will continue to follow how these claims evolve as Tesla scales production and as investors weigh the implications for autonomy, safety, and long-term profitability.
