Humanoid Walks 560km in Nine-Day Durability Test

In an experiment to put its hardware to the test, Figure AI’s latest humanoid has walked 560 km on a treadmill in nine days, logging 1.2 million steps. 

Brett Adcock, CEO and founder of Figure, gave an update on the findings when Figure 03 was still walking. “Started as a side project to stress the robot for any failures,” he wrote on X. “Let’s see how long it can go.” 

Putting Robot Durability to the Test 

A treadmill is one way to put a robot through its paces. It gives engineers a chance to spot weaknesses under sustained movement that would elude them in a brief trial. One must factor in durability for commercial purposes given the toll walking takes on a humanoid’s joints and motors. 

Figure has not released a statement on whether there was any intervention by engineers during the nine days or what the power situation was; no maintenance records or testing protocols have been disclosed by the company.  

The reported duration therefore does not mean Figure 03 operated for nine days on a single battery charge. 

Building Robots for Longer Operations 

This isn’t the first time Figure’s humanoids have gone through endurance experiments. Earlier in 2026, the company had robots at work and then charging for a 200-hour autonomous package-sorting demo, more concerned with getting logistics done. 

This test was done to see if the robot can stand up to a lot of walking. 

Figure is also ramping up on its third generation of the humanoid. At the BotQ facility in July, Adcock announced that the company had manufactured its 1,000th Figure 03. With more coming out to work in industry, reliability of the hardware is key. 

What the Test Still Needs to Prove 

Then again, a treadmill is no substitute for the rigors of a factory or warehouse where one has to contend with changing surfaces, unexpected obstacles, frequent stops and different physical tasks.  

There are no independently verified results from Figure to show how well the robot’s performance on the treadmill will hold up in the long run in such conditions. But it is still a way that provides an opportunity to examine how humanoid hardware holds up under repeated use.  

For Figure, the next challenge is to show that kind of durability in the course of everyday work and not just in a controlled setting.
