Figure AI Demonstrates Continuous Nine Day Humanoid Endurance Test

Robotics startup Figure AI recently put its latest humanoid machine through an intense physical endurance trial. According to posts on X by company founder Brett Adcock, the robot walked continuously on a treadmill for over nine days, logging nearly 350 miles and more than 1.2 million steps without stopping.

Demonstrations like this mark a crucial step toward moving robots from controlled laboratory environments into practical everyday settings. For automated machines to be genuinely useful in warehouses, factories, or home care, their physical joints, motors, and power systems must survive thousands of hours of constant friction and wear without suffering mechanical breakdowns.

However, walking in a straight line on a smooth treadmill is vastly simpler than navigating unpredictable real world terrain. It remains unclear how well these physical components will hold up when exposed to sudden bumps, heavy lifting, or awkward steps, leaving open the question of whether continuous endurance in a lab easily translates into real world reliability.
