Figure’s Humanoid Has Walked 348 Miles on a Treadmill—and It’s Still Going

Key Takeaways

• Brett Adcock says a Figure 03 has logged nine straight days of treadmill walking, covering 348 miles and 1.2 million steps.
• The test began as a side project to expose failures, and was still running when he posted the update.
• The result concerns walking endurance; the post does not establish battery runtime or reliability across other tasks.

Figure 03 has been putting in the miles. In an October 19 update on X, Figure founder Brett Adcock said the humanoid had passed nine straight days of walking on a treadmill, accumulating 348 miles—about 560 kilometers—and 1.2 million steps.

“Started as a side project to stress the robot for any failures,” Adcock wrote. “Let's see how long it can go.”

The brief update puts the focus on a practical question for humanoid manufacturers: how well their hardware holds up under repeated use. A treadmill gives engineers a controlled way to repeat the walking cycle and look for problems that might not emerge during a short demonstration.

Adcock did not provide a detailed test protocol, power arrangement, or maintenance and intervention log. The nine-day figure should therefore be read as the reported duration of the walking test, rather than time on a single charge or a measure of performance across an entire working shift.

Another endurance test for Figure 03

The test follows Figure’s 200-hour autonomous package-sorting run earlier this year. Adcock reported no hardware failures during that demonstration, which used robots rotating between work and charging. The new treadmill update examines a different activity: sustained locomotion.

Durability also matters as production grows. In July, Figure announced it had manufactured its 1,000th Figure 03. Producing more machines and keeping them working reliably are separate engineering challenges; long-duration tests help address the latter, although results from a controlled setup do not automatically translate to customer environments.

Adcock also leads Hark, whose Hark Pro service offers AI assistance with tasks such as research and bookings. This latest Figure update is a more physical progress report: a robot still walking, with no announced finish line.
