A new video surfacing from a Tesla demonstration in Miami this weekend shows the Optimus humanoid robot taking a nasty fall. But it’s not the fall itself that is raising eyebrows, it’s the specific hand movements the robot made on its way down, which strongly suggest it was mimicking a remote operator frantically removing a VR headset.

Humanoid robots are all the hype right now. Billions in investments are pouring in, and Elon Musk claims it will be a trillion-dollar product for Tesla, justifying its insane valuation.

The idea has been that with the advent of AI, robots in human form could use the new generalized artificial intelligence to replace humans in an increasingly larger number of tasks.

However, there are still many serious concerns about the effort, both at the ethical and technological levels.

Technologically, most humanoid robot demonstrations have relied on remote control by human operators – pointing to a remaining gap between the software and hardware.

We discussed how the robots at the “We, Robot” event were heavily teleoperated, despite Tesla not explicitly disclosing that fact to the public.

That was more than a year ago, and despite claims that Tesla has made “AI demos” of Optimus since, it appears the company still relies on teleoperation to control them during demonstrations.

The Tesla Optimus Miami Incident

This weekend, Tesla held an event called ‘Autonomy Visualized’ at its store in Miami. The goal was to showcase Tesla’s “Autopilot technology and Optimus.”

However, there was nothing “autonomous” at Tesla’s “autonomy” event.

Many Tesla fans were seen posting videos of a Tesla Optimus robot handing out bottles of water at the event. It was also seen posing for pictures and dancing.

On Reddit, someone posted a different video of the demonstration:

As you can see, Tesla Optimus moved its hands too quickly, causing some water bottles to drop to the ground. It then loses its balance and begins to fall backward.

But the most interesting part is that just before falling backward, both of its hands immediately shoot up to its “face” in a distinct grasping motion, as if pulling an object off its head.

The robot, of course, is not wearing anything on its head.

The motion is instantly recognizable to anyone who has used VR or watched teleoperation setups. It appears the human operator, likely located backstage or in a remote facility, removed their headset in the middle of operating the robot for unknown reasons.

Optimus faithfully replicated the motion of removing a non-existent headset as it crashed to the floor.

Here’s a look at how Tesla trained Pptimus with VR headsets in its lab:

Electrek’s Take

This is embarrassing, but not just because the robot fell. Robots fall; that’s part of the R&D process. Boston Dynamics blooper reels are legendary, and they never really eroded the company’s credibility.

The problem here is the “Wizard of Oz” moment.

The specific motion of removing the “phantom headset” destroys the illusion of autonomy Tesla tries so hard to curate.

Even recently, Musk fought back against the notion that Tesla relies on teleoperation for its Optimus demonstration. He specified that a new demo of Optimus doing kung-fu was “AI, not tele-operated”:

Musk said again during Tesla’s last earnings call in October:

“Optimus was at the Tron premiere doing kung fu, just up in the open, with Jared Leto. Nobody was controlling it. It was just doing kung fu with Jared Leto at the Tron Premier. You can see the videos online. The funny thing is, a lot of people walked past it thinking it was just a person.”

Musk keeps telling shareholders that Optimus will be the biggest product in history and that millions of units will be working in factories soon. But if they are still relying on 1:1 teleoperation to hand out water bottles right now, it feels like we are still far away from a useful generalized Optimus robot.
